I just wanted to take a moment to introduce my company and it's first product, the 170° Performance Thermostat. This t-stat was developed with the help of a few other members on SVTP last year, it is basically an OEM-style thermostat fitted with a lighter spring to lower it's opening temperature. UPDATE: As of Spring 2011 the Terminator (FORD-4D) thermostats will now be produced with a standard 170° heat motor and spring combo. I invite those of you who have already purchased one of these units to please share your experiences and to post any questions or comments regarding it in this thread. I would also like to use this thread to discuss and address known cooling system issues as well as develop further improvements.
