Start By:a. remove radiator guardb. remove hoodc. remove hydraulic oil cooler
At operating temperature, the engine coolant is hot and under pressure. Steam can cause personal injury. Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand. Remove the fill cap from the radiator slowly to relieve pressure. Cooling system conditioner alkali. Avoid contact with the skin and eyes to prevent personal injury.
1. Release the pressure in the cooling system. Drain the coolant from the radiator.
Effective July 1, 1992 regulations prohibit the venting of any refrigerant into the atmosphere. Refer to Caterpillar publication SENR3334-01 and NEDG5065-01 for the proper procedure, equipment and tools to reclaim refrigerant from any Caterpillar machine.

Escaping Freon-12 (C C12 F2 Dichloro Difluoro Methane) can cause freezing of human flesh.Do not smoke while working on air conditioning. Inhaling Freon-12 through any smoking material, although not toxic or flammable, can cause violent illness. Also heat must never be applied to a charged system. See Air Conditioning And Heating Service Manual Form No. SENR3334-01, for more information on removal and installation of lines and refrigerant from the system.
