Cooling System Water Temperature Regulator - Replace

Replace the thermostat on a regular basis in order to reduce the chance of unscheduled downtime and of problems with the cooling system. Failure to replace the engine's thermostat on a regularly scheduled basis could cause severe engine damage.

The thermostat should be replaced after the cooling system has been cleaned. Replace the thermostat while the cooling system is completely drained or while the cooling system coolant is drained to a level that is below the thermostat housing.

Caterpillar engines incorporate a shunt design cooling system. It is mandatory to always operate the engine with a thermostat.

Open the engine access door. Refer to Operation and Maintenance Manual, “Access Doors and Covers”.

Drain the coolant from the machine. See Operation and Maintenance Manual, “Cooling System Coolant (ELC) - Change” for the procedure to drain the cooling system.

Loosen the hose clamp (1) and remove the hose from the thermostat housing assembly (2).

Remove the two bolts (3) from the thermostat housing assembly. Remove the thermostat housing assembly.

Remove the seal and the thermostat from the thermostat housing assembly.

WARNING: Pressurized system: Hot coolant can cause serious burn. To open cap, stop engine, wait until radiator is cool. Then loosen cap slowly to relieve the pressure.

When a Caterpillar Extended Life Coolant is used, an extender must be added to the cooling system periodically.

Open the engine access door. Refer to Operation and Maintenance Manual, “Access Doors and Covers”.

Tilt the radiator guard upward. Refer to Operation and Maintenance Manual, “Radiator Tilting”.

Note: The radiator cap is located on the right side of the radiator.

Slowly loosen the radiator cap in order to relieve system pressure. Remove the radiator cap.

If necessary, drain enough coolant from the radiator in order to allow the addition of the coolant additive.

Add 0.17 L (0.18 qt) of cooling system additive.

Inspect the radiator cap and the gasket. If the cap or the gasket is damaged, replace the cap. Install the radiator cap.

WARNING: Personal injury can result from contact with refrigerant. Contact with refrigerant can cause frost bite. Keep face and hands away to help prevent injury. Protective goggles must always be worn when refrigerant lines are opened, even if the gauges indicate the system is empty of refrigerant. Always use precaution when a fitting is removed. Slowly loosen the fitting. If the system is still under pressure, release it slowly in a well ventilated area.

Personal injury or death can result from inhaling refrigerant through a lit cigarette. Inhaling air conditioner refrigerant gas through a lit cigarette or other smoking method or inhaling fumes released from a flame contacting air conditioner refrigerant gas, can cause bodily harm or death. Do not smoke when servicing air conditioners or wherever refrigerant gas may be present.

Use a certified recovery and recycling cart to properly remove the refrigerant from the air conditioning system.

NOTICE: If the refrigerant system has been open to the outside air (without being plugged) for more than 30 minutes, the receiver-dryer must be replaced. Moisture will enter an open refrigerant system and cause corrosion which will lead to component failure.

Refer to Service Manual, SENR5664, “Air Conditioning and Heating R-134a For All Caterpillar Machines” for the proper procedure to change the receiver-dryer assembly and for the procedure to reclaim the refrigerant gas.

Note: The receiver-dryer must also be replaced when the air conditioning system is evacuated.
