FAQ

Q1: Is this thermostat a direct fit for my Caterpillar C4.4 engine?
A: Yes, this part (4113l066) is manufactured to OEM specifications for the C4.4 engine. It is a direct bolt-on replacement. However, we always recommend verifying the part number against your old thermostat or consulting your engine’s serial number to confirm complete compatibility.

Q2: What is the correct installation procedure for this thermostat?
A: Installation should be performed by a qualified mechanic. Ensure the engine is cool and the coolant is drained. Remove the thermostat housing, replace the gasket, and install the new thermostat with the correct orientation (usually with the vent hole facing up). Reassemble the housing, refill with coolant, and bleed the cooling system to remove air pockets.

Q3: How often should the thermostat be replaced on a C4.4 engine?
A: Thermostats are a wear item. For heavy-duty applications, it is generally recommended to replace the thermostat every 1,000 to 2,000 operating hours or during major cooling system service. If you notice the engine is slow to warm up, overheating, or fluctuating in temperature, the thermostat should be inspected and replaced immediately.
