The cooling system operates under pressure which is controlled by the radiator pressure cap. Removing the cap while the system is hot may allow the escape of hot coolant and steam, causing serious burns. Before you remove the radiator cap, allow the system to cool. Use a thick cloth and turn the radiator cap slowly to the first stop to allow pressure to escape before fully removing the cap. Avoid contact with coolant. |

- Direct pressurized air or direct pressurized water through the radiator core at the back of the cooling package. Clean each core from the front to the back. Clean the rear cooler first. Then, work toward the front of the machine.
Note: Use pressurized air with a maximum pressure of 205 kPa (30 psi). Use pressurized water with a maximum pressure of 280 kPa (40 psi) .
- Straighten any bent fins.
- Close condenser core (2) . Engage latches (1) .
- Lower the hood.
Note: See Operation and Maintenance Manual, "Engine Compartment Hood - Raise/Lower" .
