3. Remove the bolts and eight plates (2) that hold the guard assemblies together.4. Remove bolts (1) that hold guard assemblies (3) in place. Remove the guard assemblies 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.
Always wear goggles when the air conditioning system is opened. This system is charged with Freon-12 (ccL2F2-Dichlorodifluoromethane) which is not toxic or flammable. But, there is a reason for caution. When Freon- 12 makes contact with a flame, lethal phosgene gas is made. INHALING FREON THROUGH A LIGHTED CIGARETTE CAN CAUSE VIOLENT ILLNESS. This system is under pressure at all times, engine running or not. HEAT MUST NEVER BE PUT ON A CHARGED SYSTEM. See AIR CONDITIONING AND HEATING SERVICE MANUAL Form No. SENR3334-01 for more information on procedures and requirements on removal and installation of lines and refrigerant for the system.

1. Make sure the core assemblies and the holes in the bottom tank are clean and free of dirt and foreign material.2. Lightly lubricate the inside diameter and the sealing surfaces of the seals, the bottom tank and the core assemblies with liquid soap. There are two different seals used on the top and bottom of the core assemblies. The distance between the projections on each end of the core assemblies is different. Make sure the correct seal is installed on each end of the core assemblies.
