Exhaust systemMake sure there are no loose supports, cracks or holes. If the sound of the
exhaust seems unusual or there is a smell of exhaust fumes, immediately
locate the trouble and correct it.MA-21
UnderbodyThe underbody is frequently exposed to corrosive substances such as those
used on icy roads or to control dust. It is very important to remove these
substances, otherwise rust will form on the floor pan, frame, fuel lines and
around the exhaust system. At the end of winter, the underbody should be
thoroughly flushed with plain water, being careful to clean those areas where
mud and dirt can easily accumulate.Ð
Fluid leaksCheck under the vehicle for fuel, oil, water or other fluid leaks after the
vehicle has been parked for a while. Water dripping from the air conditioner
after use is normal. If you should notice any leaks or gasoline fumes are
evident, check for the cause and correct it immediately.Ð
