Leak Check
WARNING: Never remove the radiator cap when the engine is hot; serious burns could be caused by high pressure fluid escaping from the radiator. Wrap a thick cloth around the cap and carefully remove it by turning it a quarter turn to allow built-up pressure to escape and then turn the cap all the way off.
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 than the specified pressure may cause radiator damage.
