Called TByrne, and they said they had them, but that someone had called them back saying that It wouldnt fit for whatever reason. They were trying to contact the supplier last I heard. Called MTI, and they said that they were using a LT1 thermostat and that it was working fine, I still passed. Does anyone know where I can get a 160 for an 04' that fits??

 

I got mine from Lingenfelter.

 

And it fit??

 

Yup, no problemo, took a whopping 4 minutes to change.

 

What stat comes stock in these 5.3s

 

I believe its 195 deg. stat.

 

I got mine from SLP. It is the one for the LS1 Corvettes. It fit fine. Took me about 20 minutes to put it in.

 

lingenfelter.com has them.

 

tbyrne has them they fit part number 100228 i installed it on 3 04's one 04 had the old drop in stat... you could tell by looking at ur houseing with out taking off the stat if u can see a lil type screw on the top of your housing you have the new 04 stat if not it's the old style... tbyrne sells the SLP it's a 160 stat... good luck...
