Proper procedures to perform these services may be
found in a service manual. See "Service and Owner
Publications" in the Index.

Exhaust System Inspection

Inspect the complete exhaust system. Inspect the body

missing or out of position parts as well as open seams,
holes, loose connections or other conditions which could

cause a heat build up in the floor pan or could let
exhaust fumes into the vehicle. See "Engine Exhaust" in
the Index.

Engine Cooling System Inspection

Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of the
cooling system and pressure cap is recommended at
least once a year.
