REMOVAL & INSTALLATION
See Figures 1, 2, 3, 4, 5 and 6
- Disconnect the negative battery cable.
Remove the radiator outlet tank from the radiator. To remove the radiator outlet tank:
- Remove the radiator from the vehicle as outlined earlier in this section.
- Using Borroughs Tool BT-8260, or an equivalent prybar, insert the end of the tool between the header tab and the radiator tank and gently bend the tab away from the radiator tank. Repeat the procedure for each tab. Do NOT open the tabs more than is necessary to for tank removal.
- Lift the radiator outlet tank from the radiator, then remove and discard the O-ring.
- Remove the retaining nuts and washers from the oil cooler inlet and outlet connections, then lift the oil cooler from the radiator outlet tank.
- Remove the radiator tank gasket from the oil cooler inlet and outlet connections, if the cooler is to be reused.
- Position the transmission oil cooler to the radiator outlet tank, then insert the inlet and outlet oil tube connectors through the holes in the radiator outlet tank.
- Install the flat washer and nut on each oil cooler connection to the retain the oil cooler in the radiator outlet tank.
- Tighten the oil cooler retaining nuts to 12-14 ft. lbs. (15-19 Nm). Tighten the intermediate fitting to 18-23 ft. lbs. (24-31 Nm).
Install the radiator outlet tank on the radiator core header. To install the outlet tank:
- Inspect the seal surface of the radiator core header to ensure it is clean and undamaged. Check to be sure that the new O-ring to be installed, is not twisted.
- Dip the new O-ring in coolant, then place it in the header groove.
- Position the tank to the header, being careful not to scratch the radiator tank sealing surfaces with the tabs.
- Clamp the radiator tank into position on the header using two header clamps, as shown in the accompanying figure, then tighten the clamps to compress the O-ring gasket.
- If locking-type pliers will be used to squeeze the header tabs against the radiator tank, install a hex nut on the pliers adjusting screw. With the jaws of the pliers closed and locked, turn the adjusting screw to position the jaws against the shank of a 27 / 64 in. (10.9mm) drill bit. Tighten the hex nut on the adjusting screw against the handle to lock the adjustment in place.
- Using a special crimping tool or locking-type pliers, squeeze header tabs down against the lip of the radiator tank base, while rotating the pliers toward the radiator tank.
- Remove the header clamps from the radiator and squeeze the tab(s) down that were behind the clamps.
- Install the radiator as outlined earlier in this section.
- Connect the negative battery cable, then start the engine and check for leaks.
