T-Stat

I have a 94 3.8 and my engine is always running hot. I added a new water temp gauge to my pod and it tells me I am running at 210F. Is that normal? I heard I should purchase a 197 T-stat, but is that the best one for my 3.8? Any help would be great.

I believe the stock t-stat opens up at 197 degrees. The mod everyone switches to is a 180 degree t-stat.

don't go under a 180degree thermo, or your car will be stuck in warm up mode all the time. Not a good thing.

What do you mean Warm up mode???

how exactly can your car get stuck in a warm up mode, b/c my car is always running warm, not overheating it will run to the R. Do i have to reset my computer?????? i took it to ford and they told me my car is in perfect conditions, they just told me my gauge needs to be recallibrated. So how do i know if my car is stuck in Warm up mode and how can i fix this??????

if you are running a stock thermo you are fine. Its those guys who run 160 degrees thermos that get their car stuck in warm up mode.

The problem is a guage problem......Warm up mode means that your car is always going to be trying to warm up, like when you turn it on in the morning......
If you were stuck in warm up mode, then your car would not warm up or even get up to the normal operating temp.

94ONAIR!!!.....a 197 t-stat is the stock rating...this is what you want....I say 210 is normal...However, Follow my Drain and refill procedure on this board and do it to your car...Then see what happens.

So your saying a 197 t-stat is the stock t-stat in my car now?? And I should keep this one? Why is it that people say the 180 is the better one and others say they have problems.

yea, if you have a stock t-stat then it is a 197. I don't know if 210 is a normal temp. but try BeirutsFinest drain and refill procedure just in case you have air in the system.

197- is the stock T-Stat....Some people say the 180 is better because they may have a chip.
If you have a chip...You can use a 180 t-stat.
I personally would not switch to a 180....I think you should stick to the stock 197 rating
Your car was built to function around a T-stat that opens at 197...Unless you have a chip that can reprogram the way your car runs...... I would stick to 197.

Stick with the 197* 210 is NOT that hot(205-210 is about right for a 197* thermostat), start to worry when you see 220+

ok about 3 months ago i put my fan to kick in, in 2nd gear the whole time, meaning as soon as i turn on my ignition my fan came on in 2nd gear and my car never got hot it was always near the C not even near the N in NORM, now will this turn on the Warm up mode by any chance????????????? Since my car will be working its best to get warm.

Just to clear things up.......Warm up mode is just a saying...There is nothing to turn on that is called warm up mode.

What it means is basically that your car is not able to reach it's operating temp...It tries, but it can't.

The answer to your question....Well if you make the fan come on too early...that's not good. You don't want an engine that runs too cold, but at the same time you don't want an engine that runs too hot.
So YES...your car will never be able to get up to operating temp if you play with the fan and make it turn on too early......Does this help?
