Product Description

The Mishimoto MMTS-CHV-01DL Low-Temperature Racing Thermostat Kit is a direct-fit performance coolant thermostat upgrade designed for 2001-2016 Chevrolet and GMC trucks equipped with the 6.6 L Duramax diesel engine (LB7, LLY, LBZ, LMM, and LML variants). This kit includes two thermostats that open at approximately 174 °F and 180 °F - lower than the typical OEM thermostat - allowing coolant to begin circulating through the system sooner. This earlier flow helps maintain cooler engine temperatures during heavy towing, hauling, or operation in hot climates by improving overall coolant management and heat rejection efficiency.

Ideal for fleet, performance, or daily-use trucks, the MMTS-CHV-01DL is supplied as a set of two thermostats with high-quality O-ring gaskets for secure sealing and simple installation in the OEM thermostat housing. Built to precise replacement tolerances and backed by Mishimoto's Limited Lifetime Warranty, this low-temperature thermostat kit offers a reliable way to enhance engine cooling performance and reduce overheating risks under demanding conditions.
