Checking the air filter element
If the air filter element is dirty, the efficiency of the engine will be impaired. Be sure to frequently check and replace with a new element within the time period established by the instructions. It is especially necessary to check and replace this element frequently when driving on a dusty road.
Fuel system check
Check the fuel system as follows:
- Check the integrity and tightness of the fuel line or the area where it connects.
- Check for damage on the surface of the fuel hose
- Check the tightness of the fuel filler cap.
Checking the hose system
Check the engine vacuum hoses, the positive crankcase breather hose, or the carbon filter hose as follows:
- Check that the hose surface is not damaged by heat or machinery.
- Check the hose for hardening, cracks, wear and tightness.
Cleanliness and care
An automobile engine is a combination of many turned, honed, polished and lapped surfaces with tolerances measured in ten-thousandths of a millimeter. When servicing engine parts, cleanliness and care are important. During assembly, a thick layer of engine oil is applied to the rubbing surfaces to protect and lubricate the surfaces during the initial period of operation. Proper cleaning and protection of machined surfaces and friction parts is part of the repair procedure. It is considered standard repair shop practice, even if not specifically stated.
Once the valve train components have been removed for service, they must be maintained in good order. They should be installed in the same places and with the same mating surfaces as before dismantling. Disconnect the battery cables before carrying out major work on the engine. If the cable is not disconnected, cable harnesses or other electrical parts may be damaged.
Maintenance without dismantling from the engine
Attention! Disconnect the negative battery cable before removing or installing any electrical components, or if tools or equipment may come into contact with exposed electrical terminals. Disconnecting the cable will help to avoid injury and mechanical damage to the car. The ignition must be disabled unless otherwise specified.
Note: When removing the air filter, the intake port must be covered. This measure will protect against accidental entry of foreign material that can enter the cylinder through the intake port and cause severe damage when the engine is started.
