Component Tests and General Diagnostics

ENGINE COOLANT LEAK CHECK





1. Confirm that the coolant level is up to the filler neck. Install a radiator cap tester and apply 160 kPa (23 psi) pressure, and then check for leakage from the radiator hose or connections.

CAUTION:
- Be sure to completely clean away any moisture from the places checked.
- When the tester is taken out, be careful not to spill any coolant from it.
- Be careful, when installing and removing the tester and when testing, not to deform the filler neck of the radiator.

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