1. Move the tensioner pulley aside by putting the wrench on the pulley center bolt and remove the belt. Lock the tensioner in this position and put on a new belt. Release tensioner.
2.5L and 3.0L engines
2. Remove the airbox and front air intake pipe.
3. Move the tensioner pulley aside by putting the wrench on the pulley center bolt and remove the belt. Put on a new belt and release the tensioner.
Hoses and connections - checking for leaks
Cooling system
1. Check the radiator and heater hoses along their entire length. Replace worn hoses. Check the reliability of the clamps and the condition of the hoses under them.
2. Inspect all components of the cooling system for leaks. A leak in the cooling system is indicated by white or rusty deposits in the area of the leak. Replace related elements or gaskets if necessary.
Supply system
1. Raise the vehicle and inspect the fuel tank and filler hose for punctures, cracks, or other damage. Check connections.
2. Check all rubber hoses and metal pipes coming from the fuel tank. Check the reliability of connections and fastenings.
Engine oil
Inspect the area around the valve cover, cylinder head, oil filter and oil sump for leaks. Replace appropriate gaskets or seals.
Automatic transmission fluid
Inspect the automatic transmission coolant hoses for damage or leaks.
Power Steering System
1. Check the condition of the hoses connecting the hydraulic fluid reservoir, pump and steering gear.
2. Check connections and tightness of clamps.
Air conditioning refrigerant
The air conditioning system is filled with pressurized liquid refrigerant. If a leak is found in the air conditioning system, contact a specialist immediately.
Brake fluid
1. Inspect the area around the brake pipe connections on the brake master cylinder and the base of the brake fluid reservoir for leaks. Check the pipe connections on the ABS hydraulic module.
2. Check the brake calipers and brake pipes under the vehicle.
Manual transmission oil
Inspect the area around the driveshaft oil seal at the rear of the transmission for signs of leakage. Check the oil level and replace the seal if necessary.
Final drive fluid
Inspect the area around the seals and seals of the driveshaft and axle shafts for leakage. Check the oil level and replace the seals if necessary.
Determining the source of the leak and the type of fluid
If the source of the leak and the type of fluid are difficult to determine immediately, leave the vehicle overnight and place a piece of clean cardboard under the suspected leak. In the morning, even a small leak will be noticeable.
Vacuum hoses
Under the influence of high temperatures inside the engine compartment, rubber and plastic hoses gradually harden and destroy, which ensure the operation of various engine components and the exhaust gas toxicity reduction system. You should periodically check the condition of the hoses, the presence of cracks and hardening, loose connections, leaks.
Part of the hoses are attached with clamps. Check the tightness of the clamps, as loosening the fastening leads to a leak. In those places where clamps are not provided, check the reliability of the hose seal on the fittings, loss of elasticity in such connections due to swelling or hardening of the hoses is not allowed, otherwise the tightness of the connection is violated.
Vacuum hoses can be distinguished by their color or by the colored strips glued to them. Vacuum hoses with different wall thicknesses, atmospheric compression resistance and heat resistance are used for different engine systems. When replacing, make sure that the new vacuum hoses exactly match the ones being replaced.
Often the hose can only be checked after it has been removed from the vehicle. If several hoses are being removed, first mark the mating fittings and hoses so as not to disturb their relative position later.
When checking the condition of the vacuum hoses, at the same time inspect the plastic tees. Check for cracks on them, as well as deformation of the hose at the point of contact with the tee fitting, which may be the cause of a leak.
To check for leaks by a characteristic sound, you can use a piece of vacuum hose with an internal diameter of about 6.0 mm. Having attached the end of the hose to the place to be checked, listen through the opposite hole in the hose. characteristic "hiss" indicates a leak.
Fuel hoses
Check the rubber fuel hoses for signs of wear or deterioration. Check hoses especially carefully at kinks and near connections, such as the connection to the fuel filter.
When replacing the fuel line on injection engines, the new line must exactly match the one used in the fuel system of engines of this type.
To fasten the fuel line hoses, spring clamps are usually used, which lose their elasticity over time. When disassembling the connection, such a clamp must be unbent, after which the elasticity is completely lost. Always replace spring clamps with screw clamps when replacing hoses.
Metal tubes
Metal pipes are commonly used in the fuel line to connect the fuel pump to the fuel pressure regulator on the injector rail. Check for deformed tubes (twisted) areas and small incipient cracks.
When replacing, only seamless steel tubes should be installed. Tubes made of copper or aluminum are not suitable, as they cannot withstand vibration loads from the engine.
Check the condition of the metal pipes and fittings of the hydraulic brake system at the junction with the main brake cylinder and dispenser (if provided), cracks and loose connections are not allowed. If any signs of brake fluid leakage are found, immediately carefully check the entire circuit of the brake hydraulic system.
Body anti-corrosion coating
To check the anti-corrosion coating of the bottom and body, you must contact the experts.
Hand brake - check and adjustment
1. Raise the rear of the vehicle and place it on stands.
2. Raise the handbrake lever 6 clicks and check that both rear wheels are locked.
3. If adjustment is necessary, raise the handbrake lever 3 clicks and loosen the adjusting nut on the balancer (arrow).
4. Rotate the brake disc so that the hole in the disc is positioned over the adjusting nut on the brake shield. With a screwdriver inserted into the hole, turn the adjusting nut until the brake pads block the brake disc. Then loosen the nut just enough so that the brake disc can turn again. Perform the same operation on the second wheel.
5. Tighten the adjusting nut on the balancer so that the pads begin to block the brake disc.
6. Check handbrake adjustment.
Checking the front suspension and steering
1. Raise the front of the car and place it on stands.
2. Inspect the boots and boots for cracks or signs of wear.
3. On models with a power steering system, inspect the system hoses and pipes and their connections for leaks.
4. Grab the wheel from above and below and try to shake it. If the free play is too great, ask an assistant to depress the brake pedal and shake the wheel again. If the free play has decreased or disappeared, then the hub bearings must be replaced. If there is still free play, then the connections or suspension mounts are worn out.
5. Grab the side of the wheel and try to shake it. Too much free play can be caused by worn hub bearings or tie rod ball joints.
6. Check up a condition of plugs of fastenings of elements of a suspension bracket.
7. Lower the vehicle to the ground and turn the steering wheel 1/8 turn to either side. If the steering wheel play is too great, check the steering gear joints and connections.
Checking the rear suspension
1. Raise the rear of the vehicle and place it on stands.
2. Check the hub bearings, bushings and rear suspension mountings as described higher for the front suspension.
