Disassemble And Assemble Radiator
Start By:
a. remove radiator and radiator guard *
*The radiator can be disassembled and assembled without removing the radiator and guard.
1. Remove eighteen bolts (2) and remove four plates (4). Remove four bolts, block off plate (1) and the gasket. Remove four bolts, upper radiator hose adapter (3) and the gasket.
2. Loosen four bolts (7). Disconnect tube assemblies (5) and (8). Remove four bolts (9) and remove coolant level switch if applicable.
3. Remove eleven bolts (11) and remove overflow tube (10), crankcase vent tube clamp (13) and radiator grill (12).
4. Fasten tool (A) and a hoist to top tank (14). Remove the twelve remaining bolts holding the top tank to the sides. Carefully remove the top tank from the core assemblies.
5. Remove the bolts that hold the core assemblies to plate assembly (15). Remove the plate assembly.
6. At the front of the radiator, remove the bolts and four strap assemblies (16).
7. Remove core assemblies (18) from the radiator bottom tank.
8. Remove seals (17) from the radiator top tank and radiator bottom tank.
9. Inspect and replace damaged parts.
NOTE: The following steps are for the assembly of the radiator.
| NOTICE |
|---|
The seals for the top tank are different from than the seals for the bottom tank. The top seals have a longer tab spacing than the bottom seals. Be sure the tabs engage with the holes in the tanks. |
10. Apply 5P3975 Rubber Lubricant to the sealing areas of seals (17) and install them in the top and bottom tanks.
11. Install core assemblies (18) into the seals in the radiator bottom tank. Install the core assemblies with the bevel edges together.
12. Install the bolts and washers that hold the core assemblies to plate assembly (15). Install the bolts that hold the plate assembly to the radiator guard. Do not tighten the bolts at this time.
13. Install the bolts and washers that hold the core assemblies to strap assemblies (16). Do not tighten the bolts at this time.
14. Carefully lower radiator tank (14) into position on the core assemblies.
15. Fasten the top tank to the sides with twelve bolts and washers. Do not tighten the bolts at this time.
16. Adjust the air gap between the core assemblies at the front of the radiator to 5 to 8 mm (.197 to .315 in.).
17. Tighten the bolts as the adjustment for each set of core assemblies are made.
18. After the air gap for all the core assemblies has been established, tighten the remaining bolts.
19. Install radiator grill, crankcase vent tube clamp and overflow tube.
20. Install coolant level switch (6) and brackets.
21. Install the gaskets, block off plate (1) and upper radiator hose adapter (3). Install plates (4).
End By:
a. install the radiator and radiator guard
