A common cause of overheating in S6D102 engines is a thermostat stuck in the closed position. This prevents coolant from reaching the radiator. If your temperature gauge spikes under load, check the 6735-61-6471 thermostat for scale buildup or mechanical failure. Replacing with a new 6735616471 unit usually restores normal thermal regulation.
The 6732-61-1620 thermostat can be tested by placing it in water and heating it. It should begin to open at its rated temperature (usually marked on the flange). If it fails to open fully or opens too slowly, your cooling system will fail to protect the engine block, leading to cracked cylinder heads or liner damage.
Our thermostats feature an OEM-standard tri-metal structure for superior durability. They are trusted by repair shops and equipment fleets globally due to their reliable performance in extreme environments, from high-heat construction sites to heavy mining operations.
We specialize in heavy-duty engine solutions for world-leading brands. Beyond the Komatsu 6735-61-6471, we provide comprehensive parts support for Cummins, Caterpillar, Isuzu, Kubota, Yanmar, and Weichai engines.
