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 ensures better cooling of your engine. Recommended for vehicles that are driven in hot climates 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.
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 skills.
Recommended for road vehicles that require a little extra cooling.
