FAQ

Q1: Is this thermostat a direct replacement for my Mitsubishi S3L engine?
Yes, this thermostat (Part #31B46-02200) is an OEM-spec replacement part designed specifically for the Mitsubishi S3L diesel engine. It matches the original size, opening temperature (82°C), and sealing surface to ensure a direct, bolt-on installation. We recommend double-checking your original part number to confirm compatibility.

Q2: How do I know if my thermostat is failing?
Common signs of a failing thermostat include the engine taking too long to reach operating temperature, the engine overheating, fluctuating temperature gauge readings, or coolant leaks near the thermostat housing. If you notice these symptoms, replacing the thermostat is a standard maintenance procedure to restore proper cooling system function.

Q3: What is the recommended installation procedure?
Installation should be performed after the engine has cooled. First, drain the coolant to below the thermostat housing level. Remove the housing bolts, replace the old thermostat and gasket, and install the new one with the correct orientation (the jiggle valve or air bleed should be at the highest point). Reinstall the housing, refill with the correct coolant mixture, and run the engine to check for leaks and proper temperature regulation. Always consult your equipment’s service manual for specific torque specs and procedures.
