Underbody Flushing

Flushing the underbody will remove any corrosive materi-
als used for ice and snow removal and dust control. At
least every spring, clean the underbody. First, loosen the
sediment packed in closed areas of the vehicle. Then,
flush the underbodywith plainwater.

Engine Cooling System

Inspect the coolant and freeze protection fluid. If the fluid
is dirty or rusty, drain, flush and refill the engine cooling
system with new coolant. Keep the coolant at the proper
mixture to ensure proper freeze protection, corrosion
protection and engine operating temperature. Inspect the
hoses. Replace the cracked, swollen, or deteriorated
hoses. Tighten the clamps. Clean the outside of the radia-
tor and the air conditioning condenser. Wash the filler cap
and the neck. Pressure test the cooling system and the
cap to help ensure proper operation.
