I was told by someone that the 5.7 TT operates on a 160 thermostat basis or something like that? Is that true?

I'm thinking about doing a Fbody Rad and new hoses. I have the Original rad and it crept up to 200 today. I'm thinking a new Rad and 160 thermostat.

I've got an F-body rad and a 160° thermostat in my car and the hottest it got on Friday afternoon was 167° in stop and go traffic with the AC running. Once I got out of traffic and was moving it was right back down to 161°. :headbang:

The F-body rad is a great deal. :yup:

Paul, you could probably go with a 180*stat in there and she'd stay around 180-185 I bet.
Wouldn't mind doing the F body rad myself. Had the T out for a nice long drive yesterday and it was creeping above 200* in stop n go with the AC on.
Once cruz'n on the hwy, temps would drop back down to 185-190*
I have the stock rad in there now with the oil cooler hooked up

Hmm how much would the whole conversion to Fbody rad cost? And what is the benefits of the motor running at a constant of 160 rather then 180-185?

Jim,

I realize that I could run a 180° stat in the car, but I prefer to run it a little cooler to help keep detonation away. I realize I MAY be getting a little more wear with the 160° stat than a 180 but I prefer the chance of a little extra wear over the chance of a little detonation. :yup:

The F-body rad cost ~ $140 at Canadian Tire when I got it and I think that was all I needed. There is a step by step section here on this site and Vortex (Steve Woods Site) that talks about using an external oil cooler but I didn't use an external oil cooler.
