180 Degree Thermostat For 5.7L and 6.4L V8 HEMI Engines

RIPP 180 Degree Thermostat for 5.7L and 6.4L V8 HEMI Engines An efficient cooling system is essential for your HEMI V8 engine. The RIPP thermostat increases the efficiency of your engine's cooling system by opening at 180°F, compared to your vehicle's standard thermostat, which opens at 203°F. This allows coolant to flow through sooner, helping to reduce and maintain cooler temperatures in the engine. This is also a great addition to vehicles with upgraded radiators and fans. The RIPP 180° thermostat does not change your vehicle's normal operating temperature; it only allows the coolant system to flow earlier. Our secret weapon: The RIPP thermostat revolutionizes engine cooling with a unique design feature. Unlike conventional thermostats, ours incorporates a longer piston, increasing thermostat valve lift. While factory thermostats typically open at 7mm, the RIPP Thermostat has an impressive 12mm lift! This extra lift is our secret weapon against heat, allowing more coolant to flow through the system, thus increasing cooling performance. Fits the following vehicles: 2005 to Current: Dodge Charger/ Challenger V8 2005 to Current: Chrysler 300 V8 2005 to Current: Dodge Durango V8 2005 to Current: Jeep Grand Cherokee V8 And many more V8 Hemi vehicles including Scat Pack, 392, and SRT models  Pro Tips: Engine Cooling Service: We recommend replacing the thermostat and flushing the cooling system every 45,000 miles or every 4 years. This helps remove any accumulated debris, contaminants, and old coolant, ensuring the proper functioning of the cooling system. Your coolant system service should also check coolant expansion tanks, hoses, and fittings.  Tuning: Installing the RIPP low-temperature thermostat is a very effective way to lower engine temperatures. Although tuning is unnecessary, with the lower-temperature thermostat installed, you can use the cooler engine conditions to fine-tune fuel and timing parameters. This can increase horsepower and torque and avoid dash lights operating in a cold environment. (i.e., installing a temp thermostat in a cold environment could trigger a warning light indicating a slow warm-up time) Coolant Mixture: The coolant-to-water mixture in an engine's cooling system regulates the engine's operating temperature. The mixture typically consists of coolant and water. The standard recommended mixture is a 50:50 mix. However, adjusting the ratio as deemed necessary in race applications or hot environments is common. A higher water content enhances the thermal conductivity of the mixture, improving its ability to transfer heat away from the engine components. This can benefit a race application where the engine is subjected to high loads and temperatures. Always consult a professional, as every vehicle will have its own variables.
