Warning
l Never remove the radiator cap while the engine is
hot.
l Wrap a thick cloth around the cap when removing it.
l When removing the radiator cap, loosen it slowly
to the first stop until the pressure in the radiator is
released, and then remove it.

Coolant Level (Engine cold)
1. Verify that the coolant level is near the radiator filler neck.
2. Remove the coolant level gauge and check the coolant level.
Coolant Quality
1. Verify that there is no buildup of rust or scale around the
radiator cap or radiator filler neck.
2. Verify that coolant is free of oil. Replace the coolant if
necessary.
Coolant Leakage
1. Connect a radiator tester (commercially available) and the
SST to the radiator filler neck.
2. Apply
103 kPa (1.05 kg/cm2, 15 psi) pressure to the
system.
3. Verify that the pressure is held.
If not, check for coolant leakage.
