TWINS
The Chinese have mastered the technology of cloning well, and in the case of Hover, no gene mutations occurred. The twin of the Japanese "Isuzu-Axiom" turned out to be quite nice and solid. Initially, the car was made only in China, but already in April 2010, assembly was launched in Gzhel, near Moscow. The Russian VIN is located under the hood, on the engine shield on the left, the Chinese one is stamped on the frame, behind the rear right wheel, when registering it is entered simply as the frame number. Our assembly, unfortunately, differs not for the better. Body parts are poorly fitted, and already in the service you have to finish the car, eliminating unacceptably large gaps. There were cases when, due to a hacky assembly, leaks appeared in the cabin through the openings rear doors and trunk lids.
The body color of the Hover is not famous for its high quality, but it also does not have serious flaws. The biggest problem was the appearance of rust under the lining of the fifth door due to the unsuccessful design of the latter. But it was already changed during the first restyling. The metal of the body is not galvanized, but with proper care somehow keeps.
THE QUIETER YOU GO, THE FURTHER YOU'LL GET
Gasoline engines are borrowed from Mitsubishi, they can be found on Pajero and Outlander. On the first "Hovers H2" under the hood even symbols were preserved Japanese manufacturer. All motors are reliable and maintainable. However, when adjusted to modern toxicity standards, they lost in dynamics. Although the Japanese, under the same restrictions, take much more off their engines.
Strange thing, during the first modernization (“Hover H3”), the 2.4 liter engine (4G64 with a capacity of 130 hp), which frankly did not pull, was replaced by an even less powerful 2-liter (4G63, 122 hp). During the second work on the bugs (“Hover H5”), the old displacement returned (4G69, 136 hp), but did not add enthusiasm. To help owners, some services offer flashing the control unit. The service is efficient and very popular.
Contrary to the permission to use the 92nd gasoline, it is recommended not to save and pour the 95th - due to the tendency of the motor to detonate. Fuel consumption can be considered adequate for the displacement of engines and the weight of the car. Don't skimp on oil changes either. Since this year, the manufacturer has reduced the interval between maintenance to 8000 km, and this is quite justified, especially when operating the Hover outside good roads. Most of the faults are supplied by the motor equipment. Most often, the crankshaft sensor and lambda probes fail. In the first case, the problem is in the quality of the node, and in the second, half the battle is in our gasoline. Sometimes there is a malfunction of the idle speed controller, otherwise there are no more defects than those of famous manufacturers.
There are no complaints about diesel engines. A very rare atmospheric volume of 2.8 liters migrated from the Axiom and is found only on pre-styling H2 models. A supercharged 2-liter diesel engine is already a joint German-Chinese development, but it has become available only on the H5. Possessing high reliability, the new diesel engine, unfortunately, is no less lazy than its gasoline brothers. A significant turbo lag releases only after 2000 rpm, which is extremely uncharacteristic for diesel engines. But here, too, flashing will come to the rescue.
DOSED LOAD
The manual transmission is quite reliable. She suffers mainly due to unprofessional tuning. When installing additional protection, its airflow is disturbed, causing overheating, from which the bearings primarily suffer. This is also observed when oil change intervals are not observed. Fortunately, the box is structurally simple and maintainable.
The clutch is not famous for its high reliability. The average life is about 80,000 km, and that is greatly reduced when driving off-road. In the spare parts market you will find reinforced analogues. They will last longer, but the shifts will become tougher. At one time, there was a clutch basket defect on the H5, which is why the gears turned on badly on a warm car. On some "Hovers" a ringing was heard release bearing. For reasons not fully understood, his body touched the petals of the basket. The defect is treated by replacing the assembly with a selective selection of parts. There is a slight adjustment of the pedal travel, but contrary to rumors, this operation does not have a significant effect on the life of the linings.
Aisin automatic transmission is only available on H5 with diesel engine. There are no problems with her.
FULL FORWARD
The transfer case control lever on the H2, when switching to the H3 model, gave way to a button (it is also found on the transitional H2).
On all Hovers front axle is engaged through an electronic clutch that controls the connection of the left wheel shaft to the front differential output shaft. With the clutch disengaged, free rotation of the front right wheel causes free rotation of the differential, as a result, other elements of the transmission do not rotate.
Switch on sensor all-wheel drive most often it becomes the culprit of malfunctions - the inability to connect or spontaneous locking of the coupling.
The mechanical part of the all-wheel drive does not cause problems. Maintenance of the dispenser comes down to timely oil changes. Bridges are reliable and designed for increased load. The main thing here is to follow the maintenance rules. There was a period when there was a factory marriage of internal anthers of CV joints. For no apparent reason, holes appeared into which grease was squeezed out. Timely replacement of covers helped.
There are spare parts on the market for fine-tuning the model: other main pairs, differentials with locks. Some services offer to raise the body. But even without fine-tuning, the off-road capabilities of the Hover meet the expectations of most owners.
DISAPPEARING SPECIES
"Hover" boasts a frame structure and reliable suspension. The only reason for complaints rear shock absorbers on restyled H3 and H5. Owners complain about their excessive rigidity, which is why the rear of the car bounces on bumps. But you can pick up analogues softer. Silent blocks of the front upper arms run 80,000 km, and the lower ones - about 100,000. Balls last about 60,000 km and usually die in pairs. Silent blocks rear suspension live approximately 100,000 km.
The braking system is poorly calculated. Due to the large weight of the car, the pads wear out very quickly: the front pads to 20,000 km, and the rear pads to 35,000. At the same time, the front brake discs are enough for 80,000 km, and the rear ones are rarely changed at all. With heavy use, they turn sour by 20,000 km brake mechanisms. It is worth doing their prevention with each change of pads. Steering malfunctions are found mainly on pre-styling H2. By about the age of five, the power steering pump may fail. The lower steering cardan connecting the angular gear and the rack is also weak. On H3, this design was abandoned. Reiki rarely break, and tie rods and tips are changed separately.
WEATHER IN THE HOUSE
The salon at first almost completely migrated from Axiom. But when upgrading to H3, they introduced their own version. Although sometimes there are transitional H3 with an old interior. The internal electrical equipment has a separate control unit. Because of his abnormal work, the electrician sometimes went crazy. During the recall campaign, this block was reflashed.
The disadvantage of the air conditioning system was the lack cabin filter(until this year) and the location of the lower refrigerant pipe, which suffers from reagents. The stove radiator requires attention - it sometimes flows on old H2.
The rain sensor can cause damage to the wipers. In winter, when the wiper blades stick to the glass, due to its operation, it cuts off the slots on the leashes. In the mechanism, plastic bushings also often break; to replace them, you will have to completely disassemble the trapezoid.
During operation vehicle many motorists notice an oil leak from under oil filter. This problem can be relevant both for owners of fairly old cars with high mileage, and for relatively new ones.
In the first case, oil flows in the area of \u200b\u200bthe oil filter due to the fact that it may not have a pressure reducing valve that does not allow excess pressure in the system. Most often, the problem manifests itself after a cold start in the winter, when the oil thickens in the crankcase. power unit. Thick lubricant simply does not have time to pass through the filter, resulting in oil being squeezed out.
Concerning modern motors, leaks for this reason are normally not allowed, since the presence of an overpressure relief valve in the design of modern systems excludes this possibility. For this reason, oil leakage from under the oil filter housing is a malfunction and becomes a reason for diagnosing the power unit.
In this article, we will talk about the reasons why oil flows from the oil filter, what to do if an oil leak is detected from under the oil filter cover or housing, and how to fix it.
To begin with, the list of reasons why oil is squeezed out in the oil filter area is quite wide. Most often, the culprit is the owner himself, who has not changed the oil filter for a long time.
- Contamination of the oil filter under certain conditions can lead to the fact that the throughput is greatly reduced, the lubricant practically does not pass through the filter media. At the same time, to protect against oil starvation of the engine, the filter design usually has a special bypass valve (allows the oil to bypass the filter element), but it is impossible to exclude the possibility of failures during its operation.
In the event that the purity and "freshness" of the filter is beyond doubt, then errors could have been made during its installation. If a leak appeared immediately after replacing the filter, it is quite possible that the filter itself is not tightened enough or the housing is not twisted (in the case of a collapsible design). This indicates the need for tightening. This procedure is carried out by hand or using a special plastic key-puller.
A prerequisite can be considered the absence of force when twisting, since constriction leads to breaks in the sealing gum and deformation of the sealing ring. If this happens, the filter must be replaced with a new one or the problem solved by replacing the damaged seal.
We add that very often during installation, car owners and mechanics forget to lubricate the above rubber sealing ring on the oil filter housing with engine oil. This leads to the fact that after the filter is twisted, its loose fit is possible, the seal can be deformed or placed skewed.
In any case, the oil filter must be removed, the integrity of the seal checked, the rubber band lubricated and the filter element installed in place, taking into account the features of its installation. It should also be remembered that a defective oil filter may come across on sale. In such a situation, the housing itself may be defective, on which there are cracks, the seal may be made of low-quality rubber, the valve in the filter does not work, etc.
- High engine oil pressure is the second most common cause of oil leaks in the oil filter area. An increase in pressure in the lubrication system can occur for various reasons, ranging from significant thickening lubricant in conjunction with exceeding the oil level and ending with certain mechanical malfunctions.
Let's start with the bypass valve. The specified valve is necessary to relieve oil pressure in case of exceeding the specified value. The valve can be located in the area of the filter holder, as well as on the oil pump itself (depending on the design features). To check, you need to get to the valve and evaluate its performance.
Jamming in the closed position results in the element not working. In this case, the device must be cleaned and washed. For cleaning, gasoline, carburetor flush, kerosene, etc. are suitable. Note that, as practice shows, it is better to replace the wedged valve when possible, especially given its relatively affordable price.
- Another reason for leaks associated with the oil filter is the problem with the threads on the fitting where the filter is screwed on. If the threads are broken or damaged, then the filter housing cannot be properly tightened during installation, as a result, oil will be squeezed out. In such a situation, it is necessary to change the fitting or cut a new thread.
It is also worth highlighting that if, that is, it becomes too liquid or viscous, then leaks often occur in the area of gaskets and seals. The oil filter is no exception. The lubricant should be selected in accordance with the requirements of the vehicle manufacturer, and also take into account the features and operating conditions.
Note that if the driver constantly uses the same type of oil, the filter is not dirty, no significant changes in weather conditions have occurred, and there are no obvious engine malfunctions, then the fact of filling a fake engine oil into the engine. It turns out that poor-quality grease simply does not have the declared properties, as a result of which leaks appear.
The way out in this situation is obvious - an immediate replacement of the filter and lubricant is necessary, and an additional one may also be needed. Finally, we add that the blockage of the pipes of the engine crankcase ventilation system leads to the fact that gases accumulate inside the internal combustion engine, pressure increases inside the engine and the oil is squeezed out through the gaskets and seals. The specified crankcase ventilation system must be checked during the diagnostic process, and also periodically cleaned for preventive purposes.
How to fix an oil filter leak
So, in most cases it is enough to fill in quality oil taking into account the manufacturer's recommendations and seasonality, change or install the oil filter correctly.
With basic skills, it is quite possible to cope with cleaning the crankcase ventilation system. This means that in most cases, practically every driver in a garage can fix an oil leak with his own hands.
As for more complex malfunctions, these include a failed pressure reducing valve and a damaged thread on the fitting for fixing the oil filter. In practice, the problem with the valve is more common, so let's separately focus on checking it.
The main task is to check the valve spring, which is located under the plug. It is she who is responsible for the operation of the device, the overall performance will depend on the state of the spring. The specified spring must be removed from the socket for inspection. The presence of scuffs, creases, bends and other defects is not allowed. Also, the spring should be tight, not loose.
If the spring can be easily stretched by hand, this indicates a weakening of this element. Also, the overall length of the spring should not be increased, indicating stretch. A decrease in length is an indication that part of the spring has broken off. In such a situation, debris must also be removed from the valve seat. Finding any defects in the spring is a reason to replace it.
Summing up
A decrease in compression in the cylinders will indicate a possible breakthrough of gases from the combustion chamber and an increase in pressure in the crankcase. The readings of the liquid pressure gauge will help to quickly determine pressure deviations in the lubrication system, if any.
Finally, we add that if oil is squeezed out from under the oil filter during start-ups or the lubricant is constantly flowing, while the engine is working and the pressure in the lubrication system is normal, and the filter itself is correctly installed and securely fixed, then the reason may be the low quality of the filter itself. In this case, before the in-depth check ICE is better first, change the filter to a proven product from a well-known manufacturer.

Japanese gasoline engines 4G63S4M, 4G64S4M, 4G69S4N, installed on Mitsubishi, have found their application on Hover. Diesel GW4D20 engine own development just like the transmission. The advantages and disadvantages of this machine are quite subjective. "What is good for a German is death for a Russian." For those who are used to riding with a “breeze”, the Hover is clearly not suitable. Well, it does not accelerate, there is not enough power, it is rather weak.
But is this feature a disadvantage? We will look for the answer in the operating and maintenance instructions, where it is indicated that maximum speed for gasoline it is 100 km/h, and for diesel it is 90 km/h. So is it worth saying that it does not pull. Who is warned is armed. frame construction an SUV with an engine capacity of 2.0 and 2.4 does not provide cross-country racing.
The transmission of our own production is designed to work in tandem with the engine. When trying to overclock and ask for more Horse power than it is, the gearbox is under severe stress, which leads to premature wear of both the box itself and the power unit. When commissioning a new Great Wall Hover, it is necessary to observe the break-in regime, which is 1000 km for gasoline 4G63S4M, 4G64S4M, 4G69S4N, and 1500 km for diesel GW4D20. The same requirement applies to engines that have passed overhaul. When all-wheel drive is turned on, the permissible speed is: 4H-40 km/h, 4L-30 km/h. At the same time, the use of 4WD is only allowed on slippery roads and in a straight line. Failure to comply with and ignorance of these rules leads to problems in the box, axles and transfer case.
The resource of the engine and transmission Hover can be increased
To increase the service life and resource, it is necessary to follow the maintenance regulations and operating rules:
- Observe the speed limit.
- Check oil level daily.
- Change the engine oil every 8000 km. run.
- In winter, start driving after warming up.
- Do not exploit diesel engine on the Idling more than 20 minutes, avoid traffic jams.
- Use only high quality fuel.
- After long trips, do not immediately turn off, let cool with the engine running.
- Do not use the machine to carry heavy items.
All rules are written in the user manual. And unfortunately, some of them are simply impossible to fulfill due to subjective and objective reasons.
You can extend the life with the help of RVS Master tribotechnical compositions. By virtue of their properties and the principle of action, which is based on the chemical reaction of substitution of iron atoms for magnesium atoms, they are rightly called repair and restoration compositions. The passage of the reaction is possible only if there is: a cast-iron block - for the engine, from which the Hover is made; ferrous metals used in the manufacture of bearings, gears and transmission shafts. As a result of the application of the RVS-Master tribological composition, a ceramic-metal layer is formed on the friction surfaces that are subject to wear. And this is not a temporary film, as is the case with oil additives. In addition, a permanent presence in the oil is not required. One or two treatments are enough, depending on the degree of wear, to increase the resource up to 120 thousand km. run. Repair and restoration compositions allow:
- Restore compression
- Reduce oil consumption
- Increase power and handling
- Stabilize idling
- Restore the contact patch on the gear teeth
- Protect against wear
- Facilitate cold start
- Reduce noise and vibration levels, both in the engine and in the transmission
- Easy and smooth gear shifting without "kicks" and bumps
The possibilities of tribological compositions are due to the characteristics of the newly formed ceramic-metal layer, which has an abnormally low coefficient of friction, is resistant to shock loads and is plastic, protects against oxidation and corrosion. As the layer wears out, it can be restored by repeated treatments.
For gasoline engines 4G63S4M, 4G64S4M, 4G69S4N, the composition is designed for 4 liters of oil.
For diesel GW4D20 - composition, designed for 6 liters of oil.
Even though the volume transmission oil in the gearbox - 3.0 l., the front axle - 1.8 l., in the rear axle - 2.7 l., we recommend using the above formulations.
Fuel for Great Wall Hover and consumption.
It is recommended to use gasoline not lower than AI-93 and diesel fuel only good quality. Such requirements are specified in technical specifications car. The use of fuel with a low octane and cetane number leads to detonation, the power of already low-torque engines decreases, and consumption increases. In addition, the content of impurities in low-quality fuel accelerates the process of mechanical wear of parts of the power unit. Particularly sensitive is the GW4D20, which is equipped with a common rail injection system.
The use of low-quality diesel fuel leads to incomplete combustion, which in turn makes it difficult to start a diesel engine in cold weather, the formation of carbon deposits in the combustion chamber, on rings and injectors, and as a result, the appearance of black smoke from exhaust pipe. The high sulfur content in diesel fuel, together with condensate, form sulfuric acid, which causes chemical corrosion of the cylinder walls of the Hover engine and pistons. Ultimately, the above reasons leading to the failure of the fuel pump, fittings, and the power unit itself.
For petrol 4G63S4M, 4G64S4M, 4G69S4N
For diesel GW4D20
Their use allows:
- Restore spray pattern
- Normalize idling
- Eliminate dips and twitches during acceleration
- Normalize acceleration dynamics
- Reduce consumption
- Compensate for the lack of lubricants in the fuel
- Clean up the injector
- Restore line pressure
The compositions do not contain chemical solvents and do not lift dirt from the tank, do not change the composition and properties of the fuel.
Gur on Hover H3 and H5
The principle of operation and maintenance is no different from hydraulic boosters of other car brands. But the quality of assembly and seals leaves much to be desired. In the event of leaks and leakage of fluid through seals and seals, which can occur on a new car, it may be enough to cause the whistle and hum of the power steering pump to appear. What to do if in warranty repair refused? Timely use to restore the power steering pump will restore the linear dimensions of the parts, reduce the gaps on the friction pairs, as a result, remove the rumble and howl, and make the steering wheel light.
Repair and restoration compositions - a new technology in repair, reliable protection from wear and increase the resource of units and machines.
