180* Thermostat for RWD 60V6

Lower temperature thermostats are designed to open sooner, and allow the engine to stay cooler in racing and hot climate applications.  Fan settings in computer controlled vehicles will need to be adjusted for the new thermostat.  This stat fits the 2.8/3.1/3.4 Iron Head engines, found in S-10s, Camaros, and Firebirds. 

160 is recommended for racing.  180 is recommended for hot climate street applications.
