Cooling System: Testing and Inspection

COOLANT LEAK CHECK
1. Loosen the radiator cap.
2. Confirm that the coolant level is up to the filler neck.





3. Install a radiator cap tester to the radiator filler neck and apply 150 kPa (21 psi, 1.53 kg/cm2) pressure. Hold for two minutes in that condition, while checking for leakage from the radiator, hose or connections.

CAUTIONS:
1. Radiator coolant may be extremely hot. Do not open the system while hot, or scalding engine coolant could spray out causing personal injury. Allow vehicle to cool before servicing this system.
2. Be sure to completely clean away any moisture from the places checked.
3. When the tester is removed, be careful not to spill any coolant from it.
4. Be careful, when installing and removing the tester and when testing, not to deform the filler neck of the radiator.

4. If there is leakage, repair or replace the appropriate part.
