The Mishimoto MMTS-RAM-94L is a 174 degree F low temperature thermostat for 1994-1998 Dodge Ram trucks with the 5.9L 12 valve Cummins. It is a direct fit replacement for the 180 degree factory thermostat.

Compared to stock it opens sooner so coolant flows earlier and the engine runs cooler, which suits warm climates and heavy towing. Swap it in any time the factory unit sticks or ages out.
