UNDERBODY MAINTENANCE
Corrosive materials used for ice and snow removal, and dust control
can collect on the underbody. If these materials are not removed,
accelerated corrosion (rust) can occur on underbody parts such as fuel
lines, frames, floor pan and exhaust system even though they have
been provided with corrosion protection.
At least every spring, flush these materials from the underbody with
plain water. Take care to clean well any areas where mud and other
debris can collect. Sediment packed in closed areas of the frame
should be loosened before being flushed. If desired, your authorized
dealer can do this for you.
