FAQ

Q: How do I confirm this thermostat fits my Komatsu engine?
A: Please verify your engine model is a Komatsu 4D106. Also, check the existing part number on your current thermostat. If it reads 124610-48620 or 48620, this is a direct replacement. If you are unsure, please provide your engine serial number for our technical team to cross-reference.

Q: What is the recommended installation procedure?
A: Installation should be performed by a qualified mechanic. Ensure the engine is cool and the coolant is drained. Replace the old thermostat, clean the housing surface, install a new gasket (not included), and refill with the correct coolant. Always test the system for leaks after installation and bleed any air from the cooling system to prevent hot spots.

Q: How often should the thermostat be replaced?
A: As part of routine cooling system maintenance, it is recommended to inspect the thermostat every 1,000 hours or 2 years of operation. Replacement is advised if the engine is overheating, taking too long to warm up, or if the thermostat is stuck open or closed. Replacing the thermostat during a coolant change is a good practice to ensure reliability.
