T-Stats.........??

My temps have been a little higher than I would like, so I tested some t-stats I had previously replaced for any number of reasons....
I tested 3 Stant Super Stats(180*). One started opening at 180* plus. The other 2 started opening quite a bit higher and fully opened at around 200*. These stats were'nt very old...

So, my question is, what t-stat has been the least problematic?

Re: T-Stats.........??

When I had overheating problems I pulled the stock t-stat out and replaced it with a stant super 180*. It didn't get any cooler so I replaced the water pump(it was leaking)....no better. I replaced the radiator with a new stock unit...still ran hot!! I then pulled the "new" super stat out and was going to run without one when a friend suggested testing it. So in to the kicthen I went with a pan and the cooking thermometer(don't tell the wife) and heated that bad boy up. POS didn't open fully until 220* so I went down to the parts store and bought the 190*(no 180* in stock) Stant....I guess it would be non-super t-stat, the cheapest one...and brought it home. Get this, it opened at 180* and was fully open at 185*...go figure. I put it in and the old girl never comes past the 1/4 mark after it opens fully even in 90*+ weather in 4LO.

Interesting side note:
I work with a guy who used to race SCCA and was a factory trained Mercedes tech, and he told me that when your antifreeze reaches temps above 220* it take twice the cooling power to cool it back down then it does at 190*. So he didn't run T-stats in his race cars just make sure he got maximum coolant flow.

Summers can be over 120 degrees here. I've seen guys take thermostats our of their rigs (no sammys) and somethimes they run hotter without. My brother (the mechanic) told me that's because a waterpump can push the fluid through the radiator so fast it really doesn't have a chance to cool down.

This is true and I wouldn't recommend not running a T-stat on a daily driver, but his race cars had high flow pumps and oversized aluminium radiators to help with heat dispersion......and going 100+mph moves a lot of air [img]images/graemlins/grin.gif[/img]

Re: T-Stats.........??

Me bad!!! The two stats that opened up around 200* were actually 195* stats......
I guess I shouldn't mess with anything mechanical while suffering from a sinus/dental infection...... [img]images/graemlins/frown.gif[/img]

Re: T-Stats.........??

Yes I have , had one cost me a head gasket . It did it's fail safe job , they replaced it according to their warranty . I had to buy the **(&amp;^ head gasket and eat that . Some warranty. If you really want a good thermostat , get one from Suzuki . So far , I've tested out 5 oem units and every one although they were quite old and crusty still opened properly at their designated temp . Aftermarket units just suck , doesn't seem to matter whose they are ....
