To prevent serious burns, do not
remove the radiator cap when the
engine is hot. Allow the engine and
coolant to cool before servicing.
1.
Place a drain pan under the radiator.
2.
Remove the radiator cap.
3.
Use pliers to remove pressure from the lower radia-
tor hose clamp while sliding the clamp away from the
hose connection (Ref. Fig. 4). Carefully pull the radi-
ator hose off the lower radiator outlet. Allow the cool-
ant to drain into a drain pan.

4.
After the coolant has drained, reconnect the lower
radiator hose and clamp.
5.
Chock the rear wheels. Lift and support the front of
the vehicle as shown in the SAFETY section.
6.
Disconnect the coolant bleed/overflow line from the
top of the radiator on the passenger side.
7.
Route the bleed/overflow line as low as possible into
a waste container.
8.
Add fresh coolant mix to the radiator until a steady
stream of coolant mix flows into the waste container
without air bubbles.
9.
Route the bleed/overflow line up to the radiator.
Reconnect the line at the top on the passenger side.
10. Fill the coolant reservoir to the MAX line.
11. Remove the jack stands and lower the front of the
vehicle as shown in the SAFETY section.
12. Start the engine and allow the engine to warm up.
Make sure the engine speed is held
at 1900 - 2200 rpm for 15 - 20 sec-
onds so the water pump has
enough force to push all the air out of the system. If
the engine is allowed to idle, the water pump seal
and valve shaft seals can be damaged.
13. Run the engine at 1900 - 2200 rpm for 15 - 20 sec-
onds to push the air out of the system.
14. If the coolant level drops in the radiator (when the
thermostat activates), add more coolant until full.
15. Replace the radiator cap.
16. Add additional coolant to the reservoir as required.
17. Check for leaks.

Radiator and Cooling Fan
Do not install unauthorized accessories in front of the
radiator or behind the cooling fan that could obstruct or
deflect air flow. Interference with air flow can lead to over-
heating and cause engine damage.
Proper radiator maintenance is important to help prevent
engine damage or failure. Check and clean the radiator
fins at the intervals indicated. See
