MAINTENANCE
Cooling System Pressure Test
Refer to Chapter 3 for cooling system pressure test procedure.
Cooling System Hoses
1. Inspect all hoses for cracks, deterioration, abrasion or
leaks. Replace if necessary.
2. Check tightness of all hose clamps.
Radiator
1. Check radiator (A) air passages for restrictions or damage.
2. Carefully straighten any bent radiator fins.
3. Remove any obstructions with compressed air or low
pressure water.
Coolant Drain / Radiator Removal
1. Remove the front bumper. Remove three bolts that secure
the bumper to the bottom of the frame. Remove six screws
(both sides) that secure the wheel well panel to the frame.
Remove two bolts that secure the top bumper to the frame.
Remove the darts that attach the plastic to the bumper.
2. Remove two mounting screws that secure the top of the
radiator to the frame. Remove the radiator cap. Pull the
radiator out of the frame at an angle.
NOTE: If you have trouble reaching the top radiator
bolts, remove four screws from the top front of the
hood liner. Prop the front of the hood up 1.5 inches
(38.10 mm) to help remove the top bolts that secure
the radiator to the frame.
3. Remove the drain plug and drain the coolant from the
radiator. Drain the coolant into a suitable container and
properly dispose of the coolant.
CAUTION
Do not over-tighten hose clamps at radiator, or
radiator fitting may distort, causing a restriction
to coolant flow. Radiator hose clamp torque is
36 in. lbs. (4 Nm).
