Default What thermostat should I buy?

What brand and temperature should I buy?
Winter is comming, and I want something that will keep the engine toasty, but not too hot, but good enough to keep it in its closed loop, so I can get the best fuel mileage.

Thanks a Bunch.

Hit up your parts store and they will have Stant.. get the lifetime and it'll be 195 for your stock temperature range

dont the autoparts stores stock a 192* thermostat? that might be your best bet giving you that extra edge over the 195* and not dropin your temps a ton

I have been using Stant Superstats in 180F for years. Rubber items just seem to last longer. Lots of heat even at 0F. Warms up just as fast as a 195 just stops a little sooner.

Will stay in closed loop at anything over 150F.

Got it changed.. stuck a 195 in it. The old one had weaker springs, and was still a bit open when i took it out. So that must've been my problem. One thing I don't understand is how it can be stuck open. I can think it'd we worn, and refusing to open against the strong springs. Guess I don't understand thermostats good enough.

I did a coolant change, and pretty well flushed my engine out. Stuck a hose into the upper engine hose, and ran water thru the engine. Prolly did not get everywheres, but just as long as I could get it thru the block.

This morning, It was chilly. I let the car warm up for 5 mins. Got in, and the darned thing was blowing HOT air!! Never thought it'd be a BIG improvement. Seems like it'll be nice this winter!

Well, started driving, went to 80 kph. Tranny shifted into OD. Another second, and the torque converter clutch engaged, and she ran good. Did not disengage at all. So far, so good.

Most of my kms are highway, or country, so having the TCC working is a big plus. This was only my first run. I don't know about later, but it should run good.

Thanks for the help!

I'd rather they failed and stuck open as opposed to stuck closed..
I had the same thing happen to my factory thermostat. The engine would never get up to 195F unless I was stuck in traffic. It was a real PITA driving that car in the middle of winter like that. It would take forever to warm up.

Its still working. Jeepers, the engine sure warms up quickly. Checked my coolant, and whatnot, and everything is good. Mileage improved quite a bit. Had to put 50 liters of fuel a week in her, now it'll last 2 weeks, we'll see.

Thanks again.
