Component Tests and General Diagnostics

System Check

WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure 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 CAP





To check radiator cap, apply pressure to cap with a tester.
Radiator cap relief pressure:
Standard 78 - 98 kPa (0.8 - 1.0 kg/cm2, 11 - 14 psi)
Limit 59 - 98 kPa (0.6 - 1.0 kg/cm2, 9 - 14 psi)

CHECKING COOLING SYSTEM FOR LEAKS
To check for leakage, apply pressure to the cooling system with a tester.
Testing pressure: 157 kPa (1.6 kg/cm2, 23 psi)

CAUTION: Higher pressure than specified may cause radiator damage.
