Inspect hoses and replace if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside of the~radiator and air
conditioning condenser. Wash the pressure cap and
neck.
To help ensure proper operation, we recommend a
pressure test
of both the cooling system and the
pressure cap.

filter every
15,000 miles (25 000 km) if the vehicle

conditions:
0 In heavy city traffic where the outside
temperature regularly reaches
90 F (32 C) or
higher.
0 In hilly or mountainous terrain.

models, you shouldn’t ever tow a trailer. See
“Towing a Trailer” in the Index.)
Uses such as found in taxi, police car or delivery

conditions, change both the fluid and filter every
100,000 miles (160 000 km).
