FLOOR PAN INSPECTIONN23FlACA common result of body leaks is a soaked floor mat pad or
carpet, and it’s not unusual to find that the water is getting in
through the floor pan to some other low point in the body. It is
possible however, for water to enter higher up and run
downward to soak the mat.
Since a soaked mat should be removed for drying, it’s a good
way to start your check. Of course, mat removal means you’ll
have to take off door sill plates and pull out seats or seat cushion.
But, this gives you a clear field for action so you can check bodyseam sealing and the plugs in the floor pan.
It’s usually not practical to water test for floor pan or
wheelhousing leaks unless a special underbody water spray
arrangement is available. As an alternate, the best way to locate
these leak points is to look for rusty seam edges or other traces
of leaks after the mats and cushions are removed. Traces of mudare an indication that the water is coming in from below.
