Mishimoto 89-93 Dodge 5.9L Cummins 87.5C High-Temperature Thermostat

You're getting a Mishimoto high-temperature thermostat and a high-quality replacement gasket with this purchase. This part is specifically made for the 1989-1993 Dodge 5.9L 12-valve Cummins engines found in models like the D250, D350, W250, and W350. These engines are well-known for their reliability and torque, and keeping them running smoothly means paying attention to the cooling system.

This thermostat is designed to activate at a higher temperature, 189.5°F, compared to the stock 180°F unit. By delaying coolant circulation, it helps your engine reach its optimal operating temperature faster. This is particularly beneficial if you live in a colder climate, as it means quicker engine warmup and more heat getting to the cabin sooner. It’s a well-built component aimed at improving your engine's performance in specific conditions.
