Cooling System Inspection / Water Pump

LC-37prose procedure

CHECKING HOSES

Check water hoses for proper attachment, leaks, cracks, damage, loose connections, chafing and deterioration.

To check radiator cap, apply pressure to cap with a tester.

Specification	Value
Radiator cap relief pressure	78 - 98 kPa (0.78 - 0.98 bar, 0.8 - 1.0 kg/cm2, 11 - 14 psi)

Radiator cap relief pressure

78 - 98 kPa (0.78 - 0.98 bar, 0.8 - 1.0 kg/cm2, 11 - 14 psi)

Pull the negative pressure valve to open it. Check that it closes completely when released.

To check for leakage, apply pressure to the cooling system with a tester.

Specification	Value
Testing pressure	157 kPa (1.57 bar, 1.6 kg/cm2, 23 psi)

Testing pressure

157 kPa (1.57 bar, 1.6 kg/cm2, 23 psi)

CAUTION

Higher than the specified pressure may cause radiator damage.
