All of which are well documented issues with the single stage thermostats. The Jet may be more money, but it's two stage designgets the engine up to temp quickly and NEVER throws a code. Now granted, I live in Fl., but when I lived in the norh Ga.mountains I used lower temp t-stats and never had a heater issue at all, even on those rare20 degree mornings...

 

the factory gasket can be used on it aslong as you dont damage it when removing the stock stat

 

Yup daytona1680.............I just covered all the bases and low and behold, my stock Tstat gasket was indeed goosed on removal.
I was careful as well so I didn't do it on dismantling.
It was split, so it's a good job I ordered a spare as trying to get one overnight to the UK would be nigh on impossible.

1-2 MPG loss!?

 

Yep.....it appeared to be that way mmstar23.
I was definately using more fuel with the 180.
It got back to normal after the stocker went in.
I'm just wondering if the engine was stuck in the "cold loop" circuit, as it always smelt rich, until it got to about a 1/4 on the temp gauge???
