Removal, installation and maintenance of the air cleaner filter element
Item Maintenance
The procedure is described in detail in Chapter Settings and ongoing maintenance.
Removal and installation
Attention! Removal
1. Disconnect the electrical wiring from the air flow meter.
2. Release the clamps securing the upper part of the air cleaner housing to the lower part.
3. Loosen the clamps and disconnect the air duct sleeve from the air flow.
4. Remove the top half of the air cleaner housing and take out the filter element.
5. Loosen the mounting nuts and remove the lower half of the air cleaner housing from the vehicle.
Attention! Installation
Installation is carried out in reverse order. After completing the installation of all components, start the engine and check it for air leaks.
Removal and installation the air duct
Removal
1. Loosen the clamps securing the air duct to the air flow meter and throttle body.
2. Loosen the muffler mounting bolt on the cylinder head cover.
3. Mark and disconnect the hoses from the muffler.
4. Remove the air duct assembly with the muffler from the vehicle.
5. If necessary, loosen the clamp and disconnect the air duct hose from the muffler.
Installation
Installation is performed in the reverse order. Make sure that the arrow on the air duct sleeve aligns with the dot mark on the muffler during installation.
Removal and installation the throttle body
Removal
1. Remove the air duct.
2. Disconnect the throttle cable from the linkage on the throttle body.
3. Drain the coolant until its level drops below the throttle body.
4. Disconnect the coolant hoses from the throttle position sensor (TPS) and the idle air switch from the throttle body (the location of the throttle body and associated components is shown in the accompanying illustration).
1 - air tract pressure chamber; 2 - throttle cable; 3 - throttle body; 4 - air duct assembly; 5 - TPS and idle speed switch
6. Disconnect the vacuum hose from the throttle body.
7. Loosen the mounting bolts, remove the throttle body with the gasket from the pressure chamber and remove it from the vehicle.
Installation
Installation is carried out in reverse order.
1. Be sure to thoroughly remove all traces of old gasket material from the mating surfaces of the plenum chamber and throttle body. If traces of carbon deposits are found in the throttle body, remove them with a special carburetor cleaner. Try to avoid getting cleaning fluid on electrical components and the spindle.
2. Before installing the throttle body, make sure the gasket is positioned correctly.
3. Tighten the bolts evenly, in a diagonal order, achieving the required force at the last stage.
4. Add coolant to the cooling system.
5. Check the TPS and adjust it if necessary.
6. Adjust the throttle cable.
7. Start the engine and check for air leaks.
Removal, installation and adjusting the throttle cable
Removal and installation
Attention! Removal
1. Disconnect the cable core from the link on the throttle body.
2. Loosen the adjusting nut and release the cable housing from the bracket.
3. Inside the car, pry the plastic cable sleeve and remove it from the top of the gas pedal lever. Release the cable core from the lever.
4. Loosen the cable bracket mounting bolts.
5. Pull the cable through the engine compartment bulkhead into the vehicle interior.
6. Check the cable and its sheath for signs of wear, pins and other damage. Replace the cable if necessary.
Attention! Installation
Installation is carried out in reverse order.
1. When installing, avoid twisting the cable and do not bend it excessively to avoid the formation of pegs.
2. Make sure that the plastic sleeve of the cable is correctly seated in the gas pedal lever.
Attention! Adjustment
1. Make sure the hand throttle is fully released.
2. Ask an assistant to fully depress the gas pedal.
3. In the engine compartment, turn the adjusting nut until the throttle valve is set to the fully open position. Tighten the adjusting nut securely.
4. Release the gas pedal and make sure that the valve is completely closed and the pedal has a free travel of about 1÷3 mm. The cable core on the throttle body should also have a small slack. Repeat the adjustment if necessary.
