6-d107 thermostat for Komatsu

This 6d107 thermostat is a direct replacement part developed for Komatsu. It is built to OEM dimensional specification, so it installs in the original position without any modification to the surrounding assembly.

Part number / cross reference

OEM and interchange reference: JWQPC200-8006B | 3973843 | 4992231 | 5257076 | 5337967 | 6746-61-621 | 504384724

Use the number from your parts book to confirm interchangeability. If your number is not listed, send it to us — we cross-check against the parts manual and confirm in writing before you pay, because a wrong part costs far more in freight and downtime than the part itself.

Compatible machines

PC200-8, QSB6.7, 6D107

Fitment can change on a serial-number break within the same model. Send us the model and serial number from the machine nameplate and we verify it against the parts manual before dispatch.

Why this part fails — and what we do differently

Cooling problems are expensive because the damage happens before the gauge moves. This 6d107 thermostat is built with the correct core depth, fin pitch and tube layout for the heat load of Komatsu machines, then pressure-tested for leaks. An undersized core is the most common reason an engine still overheats after a ‘new’ cooler is fitted.

Ordering, packing and warranty

Single pieces ship for urgent breakdowns; consolidated container or air freight is available for stock orders. Each part is packed individually in a carton with the part number labelled, and we send photographs of the actual goods plus a measurement report before shipment. Warranty: 6–12 months against manufacturing defect under normal operating conditions.
