WARNING:
●
Never remove the radiator cap when the engine is hot. Serious burns could occur from high pres-
sure coolant escaping from the radiator.
●
Wrap a thick cloth around the cap. Slowly turn it a quarter turn to allow built-up pressure to
escape. Carefully remove the cap by turning it all the way.
CHECKING COOLING SYSTEM HOSES
Check hoses for improper attachment, leaks, cracks, damage, loose connections, chafing and deterioration.
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator as follows:
CAUTION:
●
Be careful not to bend or damage the radiator fins.
●
When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radi-
ator shroud and horns.
●
Tape the harness connectors to prevent water from entering.
1.
Apply water by hose to the back side of the radiator core vertically downward.
2.
Apply water again to all radiator core surfaces once per minute.
3.
Stop washing when water flows clear coming out from the radiator.
4.
Blow air into the back side of radiator core vertically downward.
●
Use compressed air lower than 490 kPa (5 kg/cm
2
, 71 psi) and keep the air hose end more than 30 cm
(11.8 in) away from the core.
5.
Blow air again into all the radiator core surfaces once per minute until no water blows out and the core is
dry.
CHECKING COOLING SYSTEM FOR LEAKS
●
To check for leakage, apply pressure to the cooling system with
a radiator cap tester.
CAUTION:
Higher pressure than specified may cause radiator damage.
CHECKING RADIATOR CAP
●
To check radiator cap, apply pressure to cap with a radiator cap
tester.
Testing pressure
: 157 kPa (1.6 kg/cm
2
, 23 psi)

CAUTION:
●
When removing water pump assembly, be careful not to get coolant on timing belt.
●
Water pump cannot be disassembled and should be replaced as a unit.
●
After installing water pump, connect hose and clamp securely, then check for leaks using radiator
cap tester.
●
To avoid deforming timing cover, make sure there is adequate clearance between it and the hose
clamp.
