  • This unit received the designation Renault H4M, but it already had a camshaft chain drive. K4M engine belt Renault, like some others, is distinguished by multiple catalog numbers for the same, in essence, part. So the timing belt for teeth for a very common motor has many designations. This does not mean that belts are not interchangeable. When buying a belt, you can limit yourself to one of the articles, for example, Renault and use it to look for an affordable timing belt in the catalogs of trading organizations.

    Or even immediately a repair kit, a partner which can also be found by the belt number. There will be a lot of them too, you can choose the most common variant CR. Cost and choice The price of the original belt will be approximately rubles. Naturally, this is not the best choice. The original packaging always contains a part from one of the well-known manufacturers who supply products not only to the conveyor, but also to the spare parts market. Therefore, armed with the catalog numbers of specialized firms, or as they are also called, crossnumbers or crosses, you can compare prices and choose the best option.

    To date, the choice of timing belts is quite large. Rejecting counterfeits from the lower border of market prices, as well as out-of-the-box cases of the original and there are prices higher than the original ones , you can choose one of the well-known decent brands like Contitech, Bosch or Gates.

    In this case, the optimum will most likely be the Contitech CT The price of this analogue is about rubles. Although someone may be confused by the Mexican origin. For suspicious car owners, there is an alternative replacement - Contitech CT , the same, but of German origin. At a price of rubles. Work to replace the belt on the K4M The main thing to remember when replacing is that this engine does not setting marks gas distribution drive. Therefore, it is important to fix the relative position of the camshaft and crankshaft.

    This is done with special or home-made devices - a crankshaft stopper and a plate inserted into the slots on the side of the camshafts opposite from the belt.

    The slots are closed with plugs that can be damaged if handled carelessly, then they will also have to be replaced with new ones. Together with the belt, the tensioner and support roller are usually replaced. They are included if you buy a repair kit. It is also advisable to replace the crankshaft pulley mounting bolt, or at least install it on the thread lock. The bolt is also found in some repair kits.

    The hole for the crankshaft stopper is located at the end of the engine on the side of the first cylinder the first one here is considered the one on the side of the gearbox.

    The crankshaft turns until it stops in the stopper, and the first attempt is made to insert the plate into the slots of the shafts. If this is not possible, the stopper is removed, the crankshaft is turned half a turn, and after that the plate is installed. The camshafts are correctly locked. After loosening the tensioner, the belt, roller and tensioner are removed, new parts are installed.

    The belt is tensioned by turning the tensioner by the hexagon until its pointer hits the slot. Then the tensioner nut is tightened, the pointer should not go beyond the slot. The correctness of the assembly can be checked for gross errors by gently rotating the crankshaft, while the valves should not come into contact with the pistons. The article is not the only one, but it is quite enough for searching.

    Or any other, having familiarized yourself with the reputation of the manufacturer and comparing prices. The belt replacement technology is almost the same as on the K4M, the engines are similar in design. You also need to set the TDC of the first cylinder from the box side.

    Diesel belt 1,5 K9K The article number of the original belt, by which you can start the search, is It is recommended to buy the original, the price is about rubles. The analogue of Bosch 1 will be slightly more expensive, there are proposals from many other companies. On diesel engines two clamps of the same type are used, which was used for stopping the crankshaft of gasoline engines.

    One of them fixes the crankshaft in a similar way, and the second is used to stop the camshaft he is alone here through the hole in his sprocket. This engine has timing marks on the camshaft sprockets, high pressure fuel pump injection pump and crankshaft. Since the crankshaft and camshaft are fixed, then after removing the old belt and replacing the tensioner, the new belt is placed with the marks on it opposite the corresponding sprockets.

    In this case, the high pressure fuel pump is not fixed, although it must also be correctly installed strictly according to its label. The presence of marks on the new belt should be checked before dismantling the old one, if they are not there, it is necessary to count the distances in the belt teeth between the sprocket marks and apply them to the belt.

    Tighten the belt in the same way. Additional procedures when changing belts In the process of disassembly and assembly operations, the condition of the camshaft and crankshaft oil seals, sprockets, pump, auxiliary belts and their fittings should be checked. It is better to change worn-out parts or those on the verge of a resource immediately, since access is open and this can save money.

    Bolts and nuts must be finally tightened with a torque wrench according to the torque tables. In order to avoid further wear or rupture of the timing belt in Renault Fluence, it is recommended to replace it strictly according to the distance traveled. As a rule, experts advise replacing the timing belt every thousand km.

Replacing the timing belt Renault Fluence 1. But let's not beg the complexity and importance of this procedure, in order to do it, you need to try.

    It is worth considering the fact that an incorrect installation can cause a rupture, and these consequences can be called serious, since, most likely, after that you will have to do overhaul The belt should be replaced in accordance with the regulations. Preparing for replacement First of all, you will need the front front wheel on the right, for which you will have to raise the car with a jack.

    To ensure free access to all nodes, it is better to remove the wheel arch liners. A wooden block is placed under the car, and a jack is used to raise the engine to sign the mechanism. The engine sump jack should be placed as close to the crankshaft pulley as possible.

    Now you need to disconnect the support. Then the fuel supply line is dismantled. After disconnecting it, you need to take it aside to the maximum distance - as far as the tube will allow. All these actions must be done in order to ensure maximum accessibility to all timing units. The engine on Renault Fluence 1. One ensures the functioning of the intake valves, and the other - the exhaust valves. Before starting the replacement, the caps will have to be removed from the shafts.

    Buy new caps before starting work, because the old ones are likely to become unusable, as they will be removed with a screwdriver, which will compromise the integrity of these plastic parts.

    Now we need to ensure that the slots on the shafts are in a horizontal position; for this, the crankshaft must be manually rotated to the desired position of the slots.

    Then we can lock the shafts with a mm plate. The next step is to unscrew the pulley. To do this, take the head at It will be quite simple to do this, since the crankshaft will already be locked, and therefore the pulley will not scroll. Now we remove the timing case. Only 2 casings - metal and made of plastic.

    Power: h. The resource of the K4M engine in practice is more than thousand km. K4M 16 valve engine Lada Largus Cross: general information. This motor is a continuation of the development of the K7M series engine, with a new cylinder head and with 16 valves instead of 8. As already mentioned, K4M is a 16 valve engine with cast-iron monolithic cylinder block.

    The disadvantage of the cast-iron block is the more expensive and somewhat complex work on the overhaul of the motor, which require boring and honing of the cylinder block. Overhaul of a motor with sleeves "in aluminum" is carried out without machining, but spare parts for it are more expensive, plus everything - you will need to spend money on buying sleeves.

    As a result, the total cost of overhaul of the engine for each design is approximately the same. And one more important remark! The level of difficulty working on an engine with an aluminum block reduces the level of skill requirements for auto mechanics! This must be remembered. Cylinder head with two camshafts, the camshafts themselves are light. Ease of camshafts was achieved by pressing cams on a steel pipe previously this approach was the lot of sports cars.

    Reinforced pistons with steel inserts near the upper compression rings similarly reinforced pistons for Mercedes with V-engines. In general, the engine is decent, easy to maintain and repair. He has good reviews about himself from both drivers and minders.

    Yet K4M is endowed with disadvantages. Cons and malfunctions of the K4M motor. The disadvantages of the 16 valve engine K4M can be considered the high cost of spare parts. There are failures in the motor. Due to low-quality gasoline, revolutions float. A few words about the frequent malfunctions of the K4M engine. It is not uncommon for a motor to troit. The problem usually lies in the ignition coil, spark plugs, nozzles.

    The unstable operation of the K4M engine and floating revolutions are usually caused by an ignition coil or a crankshaft position sensor. Also, the cause of floating revolutions of the K4M engine is, no matter how corny it sounds, - poor quality gasoline. When servicing the K4M, it is necessary to monitor the condition of the rollers and the timing belt, as well as the multi-belt attachment belt.

    Replacing the attachment belt, as well as the timing belt, must be done every 60 thousand kilometers. An open timing belt breaks the timing mechanism with all the pop-up consequences. Repairing a gas distribution mechanism will cost a lot more money than the cost of replacing timing belts and rollers. Keep an eye on the K4M engine of your Largus Cross, and he will not let you down.

    Tuning engine Largus Cross K4M 16 valves. Chip tuning the motor, together with the replacement of the exhaust system with a catalystless one, can slightly improve engine performance.

    It is possible to get about hp. The motor modernization can be supplemented by installing shafts: - valve lift 10, phase width The phase is slightly wider than the standard - a few "horses" are added, and the car will ride more fun. For further tuning K4M need something else. For example The compressor on the K4M engine. With great desire, the PK compressor can be added to the K4M motor, which will allow to inflate about hp.

    The compression ratio of standard K4M engines is not too high, so the motor can easily withstand 0. To implement the planned engine tuning, you will need injectors from the Volga, shafts with a phase of , a straight-through exhaust. Well, of course, to configure and control the engine requires a control unit, for example - Abit. Turbine for K4M engine 16 valves. The system is similar to the system with a compressor, but instead of the PK, a TD04 turbine is installed.

    In reality, such engine configurations squeeze out just over hp. The engine does not tolerate 92nd gasoline. The oil service dealer recommends every 15 thousand km. It includes almost 5 liters of 5W or 5W oil. The air filter and candles usually last twice as long. The timing belt with rollers is replaced once every 60 thousand km, the alternator belt is usually changed with it, the water pump runs 2 - 3 replacements.

    Unlike a similar 8-valve motor, the sixteen-valve is much quieter, more economical and does not cause inconvenience with strong vibrations. However, drivers note its imperfect elasticity; at high speeds of traction, it is still not enough for confident overtaking.

    Even the owners are upset by the high cost of spare parts and their meager assortment in stores, compared to older models, as well as the lack of protection: when the timing belt breaks, the valves always bend against the pistons.

    Motorists estimate its resource at about thousand kilometers. Do you like the article? Share her.

    K4M 1. Represents development K7m. Series, with new GBC, already 16 valve. Differences Many: Another head with two camshafts, lung camshafts themselves, other pistons, hydrocomathers, etc. Motors are like a phase management, and without it, the compression ratio varies from 9. In nature, there is a modification of a given motor called K4M RS, on wide shafts, sawdwood, it gives hp. By cons of 16 valve motors, we will take the highning of the spare parts, the timing belt K4M when the flap of the valve turns, therefore, once in 60 thousand km, you need to change the rollers, belt and ridewith a calm soul.

    In addition, there are failures in the work, turns are floating from poor quality fuel. Compared with 8 valve Engine16V works quieter, more economical, no vibrations and many other advantages. In the case of cars more - Duster, Megan, etc.

    It is worth saying about frequently occurring faults, the engine K4M is not rarely troit, the problem is usually in the ignition coil, nozzles, candles, measure compression and proceed already from this. Unstable, floating turns on K4M Logan 1. Chip tuning, engine firmware K4M 1.

    You can supplement it. You can install the drives of the drive 10 phasea little wider than the standard, go a little more fun and gives some more hp. To move on, you need to come up with something else. The degree of compression of standard K4M is not too high, 0. There are no ready-made whales on this motor, but by contacting the manufacturer, you will collect the desired configuration for a specific car. To implement the project, you will use Volgov nozzles, straight-flow exhaust, shafts phaseand to configure all this online, the ABIT motor control unit will be required.

    We put the same thing. In practice, such configurations give a little over hp. It will be difficult to get outstanding dynamic indicators, but the fact that the car will go faster for sure. As for the resource Someone thinks about the resource when it comes to superfluous? What could be common between these models? This machines installed the K4M engine. This power unit has proven itself from a positive side. Many specialists, owners of these machines, characterize it as a reliable, economical motor.

    Renault K4M Tuning

    It is a logical continuation of such a line of engines as K7M, which has received minor constructive changes. What does he represent This power unit serves as a base for several models of machines of various manufacturers.

    As fuel mixes Gasoline is used, installed on recent models Renault, as well as LadalarGus, Nissanalmera. She received two camshafts separately for intake and release valves. This is reported by the inscription 16V on the body of the machine, as well as on the head of the cylinder block. If we consider the design of the cylinder block, the crankshaft, then they are the same for both versions of the motors.

    The Renault Logan 1. The owners note a slight decrease in the noise of the working power unit, this contributes to the hydrocomathers in the gas distribution mechanism of the power unit.

    A few words about the engine design The design of the DVS has four cylinders, the operating cycle consists of four cycles. Works on gasoline, the power system has a block for electronic control of fuel injection, ignition.

    The motor device has an inline arrangement of work cylinders with pistons. Their rotation is carried out in one crankshaft which also transmits rotation to two camshafts.

    The system for cooling the closed type motor has a forced circulation.

    Antifreeze is used as coolant. This must be remembered. The cylinder head has two camshafts, the camshafts themselves are lightweight. The lightness of the camshafts was achieved by pressing the cams onto a steel pipe previously this approach was the lot of sports cars.

    Reinforced pistons with steel inserts near the upper compression rings similarly reinforced pistons for Mercedes with V-shaped engines. In general, the engine is decent, easy to maintain and repair.

    It has good feedback about myself from both drivers and minders. Still, K4M is also endowed with disadvantages. Cons and malfunctions of the K4M motor.

    Disadvantages 16 valve engine K4M can be considered a high cost of spare parts. There are failures in the operation of the motor. Due to low-quality gasoline, the revolutions float. A few words about frequent malfunctions engine K4M. It is not uncommon for a motor to troit. The problem usually lies in the ignition coil, spark plugs, injectors. Unstable work K4M engine and floating speed are usually caused by the ignition coil or the crankshaft position sensor.

    Also, the reason for the floating speed strapi user registration the K4M engine is, no matter how trite it may sound, - poor quality gasoline. When servicing the K4M, it is necessary to monitor the condition of the rollers and the timing belt, as well as the multi-ribbed belt attachments The attachment belt, as well as the timing belt, must be replaced every 60 thousand kilometers.

    If you "drive" the motor further, the ribbed belt begins to delaminate, and may suddenly break, as well as the timing belt. A break in the timing belt causes a breakdown of the gas distribution mechanism with all the pop-up consequences. Repair of the gas distribution mechanism will cost where big money rather than the cost of replacing timing belts and rollers. Keep an eye on your Largus Cross's K4M engine and it won't let you down.

    Largus Cross K4M engine tuning 16 valves. Chip tuning the engine, together with replacing the exhaust system with a catalystless one, can slightly improve the engine performance. It is quite possible to get about hp. You can complement the modernization of the motor by installing shafts: - valve lift 10, phase width The phase is slightly wider than the standard - a few "horses" will be added, and the car will go more fun. For further tuning K4M something else is needed.

    For example Compressor for the K4M engine. With a great desire, a PK compressor can be added to the K4M motor, which will allow to inflate about hp. The compression ratio of standard K4M engines is not too high, so the motor can easily withstand 0. To implement the planned tuning of the engine, you will need injectors from the Volga, shafts with a phase ofdirect-flow exhaust. Well, of course, to configure and control the engine, you need a control unit, for example - Abit.

    The turbine on the K4M engine has 16 valves. The system is similar to the system with a compressor, but a TD04 turbine is installed instead of PK In reality, these engine configurations produce just over hp. Outstanding dynamic performance it will be difficult to get it, but the fact that the car will go faster is for sure.

    Over the years of Renault's existence, the concern's products have been equipped with different engines. Sincethe K4M engine has been installed on the popular models Logan, Sandero, etc. Overview and characteristics The next important point is air filterits condition directly affects the operation of the engine: the worse the air passes through the filter, the stronger engine "Suffocates", loses power, starts to work with failures.

    According to the regulations, the air filter should be changed every two years, or after about 30 thousand mileage. Air filter: If the car is operated in a dusty environment, it should be changed more often.

    The engine is quite sensitive to fuel and does not tolerate 92 brands well, although the manufacturer does not give a direct ban on 92 gasoline.
