Super High Flow low temp 180 degree High Flow thermostat w/gasket for all Chevy, GMC pick-ups, Suburbans, Tahoes, G/P Van, and Hummer H1's 92-96 with 6.5 Turbo or non-turbo Diesel Engines with the single thermostat housing. NOW FAIL-SAFE DESIGN*

Factory thermostat is 195 and everyone for years has been trying to find a 180 to help keep temps down. This t-stat is rare and impossible to find at your auto parts store. Brand new, with a one year replacement warranty from SSDiesel SupplyTM.

Will flow 33% more coolant then stock.

180 degrees is the "sweet-spot" where the 6.5 runs the best. All stainless steel and brass construction and 100% MADE IN USA!!! Custom setting of 180 DF and w/air bleed hole for smooth operation.


  • In overheating situations, the Fail-Safe thermostat automatically locks in the open position, delivering maximum coolant to the engine
  • When standard thermostats fail, they lock in the closed position, prevent coolant flow and possibly cause serious damage to your engine. The Fail-Safe thermostat has a patented safeguard against overheating damage. Upon system failure, the Fail-Safe locks in the open position. Coolant flows freely. Helps protect the engine in the event of overheating.
