Removal
The radiator and oil cooler may be hot. To avoid
possible burns, allow the engine and cooling
systems to cool before working on the oil cooler.
1. Carefully lift the hydraulic oil cooler or the transmis-
sion heat exchanger up and out of its support hooks
(Fig. 102).
2. Disconnect the hydraulic hoses at each end of the
cooler/heat exchanger and remove it from the vehicle.
Inspection
Use eye protection such as goggles when using
compressed air.
1. Back flush oil cooler with cleaning solvent. After cool-
er is clean, make sure all solvent is drained from the
cooler.
2. Dry inside of oil cooler using compressed air in the
opposite direction of the oil flow.
3. Plug both ends of oil cooler. Clean exterior of cooler.
Make sure fins are clear of dirt and debris.
4. The oil cooler should be free of corrosion, cracked
tubes, and excessive pitting of tubes.

to the hydraulic straight fitting threads before installing
into cooler/heat exchanger (Fig. 103). Reconnect the
hydraulic hoses.
