Product Description

The Mishimoto MMTS-Y61-97 Racing Thermostat is a direct-fit performance upgrade engineered for the Nissan Patrol Y61 equipped with the 4.8L TB48DE engine from 1997 through 2013. This racing thermostat opens at approximately 140 °F, lower than the stock thermostat's ~180 °F activation point, allowing coolant to begin circulating earlier in the warm-up cycle. The earlier coolant flow helps improve overall engine cooling efficiency and can assist with reducing peak operating temperatures during hot-climate driving, heavy loads, or off-road use.

Installation is designed to be a direct replacement into the factory thermostat housing with no modification required. Precision calibrated and backed by Mishimoto's Lifetime Warranty, the MMTS-Y61-97 delivers improved thermal performance and dependable operation whether you're tackling tough terrain, hauling heavy loads, or seeking better cooling in daily driving situations.
