Removal
1. The heat exchanger is mounted on the top of the gearbox housing. To access the heat exchanger, remove the air supply pipes to the engine.
2. Using a clamp, pinch both coolant supply hoses to the heat exchanger to reduce coolant loss.
3. Loosen the clamps and disconnect both coolant hoses from the heat exchanger.
4. Unscrew the central heat exchanger mounting bolt and remove the heat exchanger from the gearbox. Remove two sealing rings from the heat exchanger.
