was looking into getting these two as a combo, thermal switch and stat, was wondering how this will effect MPG? i was gonna do this on a old car i use to have and it effected closed loop ect ect

 

i do not believe the j's parts will work on the usdm fit. there is a thread around here somewhere of aj-racing trying it and it didnt work out.

 

You are correct.

 

o dang! i didnt even think about that i figured it would be the same

 

Apologize for a reply that is very late in time. This is just a fact I have a problem with my thermostat, but im not 100% sure yet. It started when Ive noticed that if i go outside to start my car up in the morning, and leave it out there for lets say 10 minutes, its barley warmed up. What’s going on with my auto? Anyone encountered this issue?
