I tried to get a 180 degree thermostat for my 2002 4.3 at the local parts house with no luck. Can someone give me a Stant , other recognizable brand number or a crossover for this thermostat

How would a thermostat throw a SES light? The only thing that the performance one might benefit is fail safe. Meaning if it dies, it dies open not closed. But almost all stants and other brands have that.
With the hypertech your paying for the name. Thats about it. A local checker store around here sells 160 thermos for a trucks for around 6 bucks I think. $20+ for a stat is a joke.
You drove one day, what for a couple hours, and determined a 160 stat was causing bad gas mileage???? Ever think that the gas mileage was no good because you were racing? Thermostats shouldn't affect fuel economy unless its an extreme high or low temp. Here in FL, you should get better fuel economy with a 160, in Alaska that may not be the case.obrien said:yes gas milage sucks with a 160. I used one in my truck for about a day, just enough to go to the track, and I changed it back to the stock stat. I couldn't find a 180 which is what I really wanted
