FAQ

Q1: How do I verify that this thermostat (4973373) fits my Cummins N14 engine?
A: First, check the part number stamped on your current thermostat. If it matches 4973373, it is a direct replacement. If not, please provide us with your engine’s serial number or the old part number for cross-referencing. This thermostat is designed for standard N14 cooling systems, but variations exist in different applications (e.g., marine vs. genset).

Q2: What is the correct installation procedure for this thermostat?
A: Installation is straightforward. Ensure the engine is cool and the cooling system is depressurized. Remove the old thermostat housing, clean the mating surfaces, install the new thermostat with the correct orientation (usually with the air bleed valve facing up), and replace the gasket. Re-torque the housing bolts to the manufacturer’s specifications. Always refill and bleed the cooling system after installation.

Q3: How often should the thermostat be replaced on a Cummins N14 engine?
A: As a preventive maintenance measure, it is recommended to inspect the thermostat every 1,000-2,000 operating hours or during major engine overhauls. Replace it if the engine is slow to warm up, overheating, or if the part shows signs of corrosion or mechanical damage. Using a new thermostat during a water pump replacement is also a common best practice.
