A: Floor Area
1. Inspect all of the bulkhead grommets and plugs both in the passenger compartment and under the hood (see Figure 1). Replace any missing plugs or grommets. Make sure all plugs and grommets are fully seated. If water tracks are present inside the vehicle, seal the area with clear seam sealer or RTV sealant. Clean and seal the seam between the brake booster reinforcement plate and the bulkhead with clear RTV sealant as shown. Spray water directly on the bulkhead from in the engine compartment. This area receives heavy road spray and is often overlooked when diagnosing water leaks. Seal any suspect areas such as holes for heater a/c plumbing.
2. Inspect the kick panel areas (Figure 2). Remove the speaker grilles and speakers. This area is visible through the speaker opening. Carefully check the antenna plug on vehicles shipped without a radio. Seal the plugs with clear seam sealer or RTV. Seal the body seams with clear seam sealer or aerosol sealer such as Kent Industries Aerosol Leak Check or equivalent.
