General description
1. Models with extended equipment may be equipped with an engine oil cooler, which is designed to maintain the operating temperature of the oil when the engine is running in severe operating conditions. The cooler is mounted on the right side of the radiator, and is connected to the engine by two rubber hoses. The feed hose is attached to the drive chain cover, just above the outlet of the oil pump, and the return hose is attached to the front of the cylinder block, just to the right of the oil filter.
Removal
2. Place a suitable container under the cooler couplings on the engine block. Loosen and remove the banjo bolts, noting the location of the sealing washers that are installed on both sides of each coupling. The washers must be replaced.
3. Allow the oil to drain from the cooler hoses into a container, then plug the ends of the hoses and the openings in the cylinder block to prevent dirt from entering the lubrication system.
4. Loosen and remove the mounting bolt and remove the engine oil cooler from the engine compartment.
Installation
5. Reinstall in reverse order, place new sealing washers on each side of the couplings and tighten all bolts securely. Finally, top up the oil level, then run the engine briefly to allow the oil to fill the oil cooler and check the oil level again.
