I have a 95 Eagle Talon ESi with the 420A.
Not long ago, I had to replace a bad thermostat, so I thought I'd make the "smart" move and install a Fail-Safe. After installing it, I noticed the coolant temp gauge read slightly lower than usual, but nothing that concerned me. However, for the last couple of weeks, I noticed that it isn't even warming up at all. I have almost no heat from the heater, and my fuel economy is completely TANKED. I did notice that with slower in town driving the gauge will climb about 1/3rd of the way up, but during normal cruising, it climbs at best a quarter of an inch.
Are these the symptoms of a (spontaneously) failed open thermostat? Or something else? At first I was thinking a bad coolant temp sensor(based on the BAD fuel economy), but that seems to be working just fine.
