For those of you who dont know I live in Florida, it gets cold here maybe 1 or 2 months out of the year. Now I want to take my thermostat completely out and not replace it, I have done it before on my Camaro and it ran cooler than ever, can I do the same thing with the All-Trac?

It's a bad idea. The thermostat is there to keep you from overcooling, the only thermostat that will cause you to run too hot is one that is not working properly. The engine is meant to run at operating temp, not however cold you can get it. But judging from your last response on a topic of engine cooling, you don't want to hear it and are probably going to pull your tstat out anyway, so whatever.

ok master mechanic..............Yes you can take out your tstat. I never ran one in any 3sgte car I have ever had.....

you got to think where I live, it will get about 60 maybe 50 degrees 1 or 2 days out of the year, the rest of the time it will be 75-95 out and most of the year its 85-95.


BurnyD you seriously never ran a t-stat on any of your 3sgte's? did they run ok? no ses lights?

dude youll be fine...... I never ran a tstat on any of the following

93 alltrac
94 6gc st185 swap
91 mr2

and the alltrac + 6gc where winter driven here in pittsburgh.

I run no t-stat during the summer months as well, never had a problem, no CEL. On a really hot day(40*F) the temp would still climb about half way and that was without A/C and the fan running constant. Only problem with it not being there is if the engine coolant doesnt reach operating temp than the ecu will run rich and pull timing.

40*F is a hot day? lol

currently with stock t-stat the car gets so hot that you cannot sit or even touch the hood, and thats with the fan running at all time.

you get no benefits from taking it out. if anything, you can damage the motor because it will be too cold while you are on the highway boosting. its like a 20$ part. just buy a new one and stick it in.

if you want better cooling of your hood and engine bay, you'll need to upgrade to something like the CS front bumper and hood, and get a fmic. the biggest source of heat in the engine bay is that horrible stock top mount IC. taking out the thermostat will not help at all.

so, how cold is "too cold"?

not having a thermastat is a good way to heat shock the block, ive seen it/had it hapen. if you want more cooling from a stock thermast drill holes around the flat piece the size of bb's, i drill 2 in mine, somtimes 4, helps out and wont over cool it

whatever is lower then the operating temp for the motor, aka what your thermostat is rated at. running the car too cold, is just as bad as running it too hot.

my 3s stays nice and cool, because of all the gt4 vents in my hood and bumper. the CS hood/bumper, would give you the same benefits on a 5th gen.

The purpose of a thermostat is to keep the engine at optimal running temperature. Your performance will be best at the manufacturers recomended operating temperature. If it runs either too hot or too cold, your performance will suffer. Wear and tear on all moving parts will be greater at any temperature other then the recomended operating temperature. All engines are designed to run at peak performance at a specified temperature. Running too hot or too cold will also effect the longevity of your engine.

exactly, not to mention having the thermat out can actully make you run HOTTER. it movems the volume of water too fast thoruhg the block at higher rpms to cool it down therefore making it hotter, though this usully only happens on V blocks it could happen on an I block

just drill 2 bb sized holes in it, thats the most effective way IMO

Looks like I will be drilling holes in the current thermostat, and what is the Optimal running temperature for the 3SGTE? and I dont mean manufacture recomended temp since 90% of Auto makers make their car's run hotter than optimal for emisions purposes.
