Radiator Surge Tank Replacement.
- Remove the clamp at the radiator inlet using
J 38185
.
- Remove the inlet hose from the radiator.
- Remove the clamp at the radiator outlet using
J 38185
.
- Remove the outlet hose from the radiator.
- Remove the upper air baffle assembly. Refer to
Radiator Air Upper Baffle and Deflector Replacement.
- Disconnect the automatic transmission cooler lines. Refer to
Transmission Fluid Cooler Hose/Pipe Quick-Connect Fitting Disconnection and Connection for the Allison transmission.
- Disconnect the engine oil cooler lines. Refer to
Engine Oil Cooler Pipe/Hose Quick Connect Fitting.
- Remove the outlet heater hose clamp at the radiator using
J 38185
.
- Remove the outlet heater hose from the radiator.
- Remove the fan shroud bolts from the top of the radiator support.
- Remove the upper radiator support bracket bolts. Refer to
Radiator Support Replacement.
- Remove the air cooler bolts.
- Remove the upper transmission oil cooler bracket nuts and reposition the bracket.
- Remove the radiator (2).
- Remove the radiator insulators (1,3).
- Inspect the following components. Replace the components as necessary:
Installation Procedure
- Install the radiator insulators (1,3).
- Install the radiator (2).
- Install the air cooler bolts.
- Reposition the upper transmission oil cooler bracket.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
