77 Degree Racing Thermostat for Dodge Viper
If your Viper runs a little hot, lower the temperature with a 77 degree thermostat.
The thermostat fits perfectly into your OEM thermostat housing and provides better cooling for your engine. Recommended for vehicles that operate in a hot climate or in stop-and-go traffic.
Once the engine is fully warmed up, the Viper thermostat opens at a lower temperature than the stock thermostat, allowing coolant to flow through the engine faster, reducing engine temperatures and keeping it cooler, improving the long-term reliability of your vehicle's cooling components.
The installation is simple and only requires the replacement of the old OEM unit and the installation of the new thermostat.
Installation can be carried out with simple tools and requires only moderate manual dexterity.
Recommended for road vehicles that need a little extra cooling.
