3. LUBRICATION

1)Anti-friction

The oil makes a thin film on the surface of sliding components to reduce the wear due to friction.

2)Cooling

The friction makes the heat on the components. The oil absorbs the heat and radiates it or cools it down.

3) Sealing

The piston ring on the piston seals the cylinder. The oil gets into the clearance in piston ring to secure 

the sealing for compression pressure and combustion gas.

4) Anti-corrosion

The oil generates the thin film on the surface of components to prevent the material from contacting with 

air, water and corrosive gas.

5) Cleaning

The oil transfers the residue of material due to friction, oxidized substance, and carbonized substance 

while circulating in the engine by oil pump.

2. INSPECTION

Possible Cause

Action

Coolant level 
is too low

- Leak from the radiator
- Leak from the auxiliary reservoir
- Leak from the heater core

- Replace the radiator
- Replace the auxiliary reservoir
- Replace the heater

- Leak from the coolant hose connections
- Damaged coolant hose

- Reconnect the hose or replace 
  the clamp
- Replace the hose

- Leak from the water pump gasket
- Leak from the water pump internal seal

- Replace the gasket
- Replace the water pump

- Leak from the water inlet cap
- Leak from the thermostat housing

- Replace the water inlet cap 
  gasket
- Replace the thermostat sealing

- Incorrect tightening torque of the 
  cylinder head bolts
- Damaged cylinder head gasket

- Tighten the bolts to the specified 
  torque
- Replace the cylinder head 
  gasket

Coolant 
temperature is 
too high

- Coolant leakage (Coolant level is low)
- Improper coolant mixture ratio
- Kinked coolant hose

- Add coolant
- Check the coolant concentration 
  (Anti-freeze)
- Repair or replace the hose

- Defective thermostat
- Defective water pump
- Defective radiator
- Defective auxiliary reservoir or tank cap

- Replace the thermostat
- Replace the water pump
- Replace the radiator
- Replace the auxiliary reservoir 
  or tank cap

- Cracks on the cylinder block or cylinder 
  head
- Clogged coolant passages in the 
  cylinder block or cylinder head
