2. INSPECTION

Problem

Possible Cause

Action

Coolant level is 
too low

- Leak from the radiator
- Leak from the coolant auxiliary tank
- Leak from the heater core

- Change the radiator
- Change the coolant auxiliary tank
- Change the heater

- Leak from the coolant hose 
  connections
- Damaged coolant hose

- Reconnect the hose or replace 
  the clamp
- Change the hose

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

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

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

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

- Tighten the bolts to the specified 
  torque
- Change 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 coolant auxiliary tank or 
  tank cap

- Change the thermostat
- Change the water pump
- Change the radiator

1) Coolant Level Check

Park the vehicle on level ground and apply the parking brake. Stop the engine and wait until it is 

cooled down.

The coolant level should be between the MAX and MIN mark on the coolant reservoir.
Check the coolant level. If the level is below the “MIN” mark, immediately add coolant.

1.

2.

Scalding hot coolant and steam could be blown out under pressure, which could cause serious 

injury. Never remove the coolant reservoir cap when the engine and radiator are hot.

Avoid any direct contact of the coolant to the painted body of the vehicle.

2) Leak Test

Release the pressure in the system by 

loosening the pressure cap of the coolant 

reservoir slightly. Then, remove the pressure 

cap completely.

1.

Never open the cap until the coolant 
temperature becomes under 90℃ to 

prevent any burn.

Add the coolant so that the coolant level is 

between MAX and MIN mark on the coolant 

auxiliary tank.

Connect the tester to the tank filler and apply 

pressure (1.4 bar).

Check all the coolant hoses, pipes and 

connections for leaks when the pressure of 

the tester drops, and replace or tighten, if 

necessary.
