Component Tests and General Diagnostics

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

NOTE:
- After testing, clean up all coolant seepage from areas of leakage.
- When the tester is removed, be careful not to spill any coolant.
- During tester usage, do not deform the filler neck of the radiator.

3. If leakage is present, repair or replace the appropriate part.
