Localized Testing (Spot Testing). Pontiac Sun Runner - 4WD (Canada) 1998

For 1990-2009 cars

Important: Pinpoint the leak area before you make any repair. Random repair may only temporarily restrict water entry, and make future diagnosis and repair more difficult. Continue localized testing in the same general area in order to confirm that all the leaks are located.

You may perform the localized test using either water or air. Begin the test at the base of the suspected area and continue up slowly until you locate the leak.
