Mishimoto 87.5°C Thermostat for 1989–1993 Dodge 5.9L Cummins Trucks

Description

This low-temperature thermostat from Mishimoto reduces engine coolant operating temperature for first-generation 5.9L 12-valve Cummins engines in 1989–1993 Dodge trucks by opening earlier than stock, allowing coolant to flow through the radiator sooner to help manage heat under warm-climate driving or heavy towing. Designed specifically for the 1989–1993 5.9L 12v Cummins platform, the unit activates at 174.2°F (compared with the factory 180°F) and ships with a high-quality replacement gasket for straightforward installation.
