Service Procedure
A. Inspect Radiator Inlet Hose:1. Raise the hood
2. Remove the left side air inlet to air cleaner housing tube.
3. Inspect the radiator inlet hose position (Figure 1):
> If there is GREATER THAN 1/2" (12.5 mm) clearance between inlet hose and the two (2) bosses on the radiator shroud (Figure 2), no further action is necessary. Install the air inlet to air cleaner housing tube and return the vehicle to the customer.
> If there is LESS THAN 1/2"(12.5 mm) clearance between the inlet hose and the two (2) bosses on the radiator shroud and the hose shows no evidence of contact with the bosses (Figure 2), the hose must be repositioned. Continue with Step 4.
> If there is LESS THAN 1/2" (12.5 mm) clearance between the inlet hose and the radiator shroud bosses (Figure 2), and the hose has visible evidence of hose wear from contact with the bosses, the hose must be replaced. Continue with Section B - Replace Radiator Inlet Hose.
NOTE:
A hose with rub mark(s) only (no wear/notch in hose) does not require replacement.
4. Place a reference mark at the index arrow on the radiator inlet nipple (Figure 3).
5. With the engine cold, loosen the hose clamp at the radiator inlet.
6 Rotate the radiator inlet hose clockwise (toward the left front fender) until there is 1/2" (12.5 mm) clearance between the radiator inlet hose and the radiator fan shroud bosses (Figure 3).
7. Tighten the radiator inlet hose clamp to 29 in-lbs (3.3 Nm).
IMPORTANT:
Check the clearance again after the hose clamp is tightened to ensure that the proper clearance is maintained.
8. Install the air inlet to air cleaner housing tube.
B. Replace Radiator Inlet Hose:
1. Raise the vehicle on an appropriate hoist.
2. Remove the engine under cover.
3. Attach one end of a hose to the radiator draincock. Place the other end into a clean container.
4. Open the draincock and drain the coolant from the radiator until the coolant level is below the radiator inlet. Close the draincock and save the coolant for later reuse.
5. Lower the vehicle.
6. Loosen the radiator inlet hose clamp at the radiator nipple and disconnect the inlet hose from the radiator. Save the clamp for later reuse.
7. Using a die grinder or cut-off wheel, cut the radiator clamp at the other end of the inlet hose and disconnect the inlet hose from the tee near the top center of the radiator. Discard the inlet hose.
CAUTION:
Use care to not damage the plastic tee.
8. Install the provided hose onto the tee and radiator inlet nipple. Rotate the radiator inlet hose clockwise (toward the left front fender) on the radiator nipple until there is 1/2" (12.5 mm) clearance between the radiator inlet hose and the radiator fan shroud bosses. Secure the hose with the provided clamp and the original clamp. Tighten the clamps to 29 in-lbs (3.3 N.m).
IMPORTANT:
Check the clearance again after the hose clamps are tightened to ensure that the proper clearance is maintained.
9. Install the air inlet to air cleaner housing tube.
10. Fill the radiator with the original saved coolant. Add additional coolant if necessary.
11. With the heater control unit in the HEAT position, operate the engine. Make sure that the coolant recovery reservoir cap is installed.
12. Top off the coolant recovery reservoir as necessary.
