Reduced engine temperatures add life to your engine and provide a denser air/fuel mixture. This helps produce more horsepower. Consistent control of engine temperature allows an engine to operate at its peak efficiency no matter what the driving conditions. The factory 205° thermostat simply cycles open and closed; this reduces cooling efficiency in any engine. With the 180° thermostat you get consistent engine cooling and a precise metering of water throughout the engine. Constructed of stainless steel the HHP 180° thermostat is the best choice for use in your HEMI engine. INCLUDES: Thermostat & Replacement Gasket NOTE:This thermostat is comparable to or better than all other popular thermostats on the market. These exact thermostats, manufactured by Motorad, are offered by other manufacturers at much higher prices. At HHP, we cut out the middle-man, saving you up to 50% on this item. RECOMMENDED FAN SETTINGS FOR USE WITH THE DIABLO TUNING: In order to take full advantage of your HHP 180 degree thermostat, on applicable vehicles with adjustable fan settings, we recommend the following fan temperature adjustments on your Diablosport tuner. Set All 9 Fan Settings (both Air Condition On and AC Off) to: All HS (High Speed) Fan Settings to 194 Degrees All LS (Low Speed) Fan Settings to 189 Degrees All MS (Med. Speed) Fan Settings to 192 Degrees *Failure to set your fan settings at these higher temps will result in your fans constantly running and can cause your fan motors to burn out prematurely.
