1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle (Service and Repair).
2. Check for obvious deterioration on the floor pan.
3. Check for loose dirt and corrosion around the inside of the floor pan reinforcement member access holes. This is the first indication that corrosion may exist in hidden areas.
Perform all repairs before the final cleaning and protective treatment is performed.
4. Using a chisel, ensure that the drain provisions in the floor pan reinforcement members are open.
Open the drain holes in the body side panels using a punch and a drift.
