1. Loosen 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 160 kPa (23 psi) pressure. Hold for two minutes in
that condition, while checking 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 removed, 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.
4. If there is leakage, repair or replace the appropriate part.
