Let's talk FE thermostats..

You know Jim, I've never run it without a stat. Too cold can be almost as bad as too hot, especially with an aluminum motor. If I still get these temp swings with the new stat (which ever one I go with) then no stat would be the next step. Odd thing is, the cooler it got outside the higher the temp would spike. RickL experienced the same symptoms with a Mr. Gasket (Robertshaw) stat in his FE as I did. The problem went away after he replaced it with a different mfr's stat. There were also similar hits on google about the subject too. That gives me a glimmer of hope. I checked with NAPA today on the way home from work and they carry the Stant line, semi-reboxed with the NAPA logo on it. I've got some breathing room as far as time goes so I think I'll do some more research. I just wish someone else made a hi-flow stat other than Robertshaw.

Dave .. just went out to the garage and checked . My thermostat is a Stant # 13478 , 180 degree , and it has two 1/8" holes drilled in it . Also says it is made in the USA . Maybe that`s why I haven`t had a problem .

I Was just thinking that by removing the t-stat altogether (not permanently) maybe it would force something else into the light, such as a flow restriction etc.

The NAPA Stant is what I am running after all the trial and error. Keep us posted...

Bob and Jim, I'll probably go with the Stant. I'll let everyone know how it works out. Just maybe I'm make more of an issue out of this than I should?

I have $5 that says after you get that fan going, your temp range will be no more than 15 degrees above your t-stat rating.

elmariachi The size is #14 and he can't keep the thing from being matted on the floor. I will take that $5.00 bet. Side note, he is also adding more power to the car. about 250-300 HP. Rick L.

That's funny. Dave, I think Rick has identified your overheating problem.

Rick, I take offense to that size 14 statement.... They're not one size bigger than a 12.

I'm looking at installing a custom "fogger" port injected system, a 300hp shot .. w/a progressive digital controller too. I like nice round numbers, say 1000 hp. That'll do, for now. Now that I've got those "nearly twisted in half" 28 spline axles replaced with some Dutchman 31 spline units I'm ready for some real power adders. I need to get this turd to run faster than the daily driver .. I need it to do better than a 128 trap speed.

Jim, I honestly feel that everything I've done WILL take care of the problem. I'm just trying to get all the over-kill I can get while I'm at it. I really don't want to deal with this cooling issue again. It seems every thing I do with this darn Cobra I end up doing it 2 or 3 times before I get it right It seems to be par for the course though...
