coolant, then install it on the pressure tester.
RADIATOR
CAP
2. Apply a pressure of 93- 123 kPa (0.95- 1.25 kgf/cm2,
14-18 psi).
3. Check for a drop in pressure.
4. If the pressure drops, replace the cap.
1. Wait until the engine is cool, then carefully remove
the radiator cap and fill the radiator with engine
coolant to the top of the filler neck.
2. Attach the pressure tester to the radiator and apply
a pressure of 93-123 kPa (0.95 - 1.25 kgf/cm2, 14 -
18
psi).
