Low temp thermostat

Is this a good investment? Can you tell a difference? Will your car run better? I have a few bolt-ons, but mostly stock. The car is daily driven. Any input

you have to go into the computer to set it at a lower temp

**SSTODD** · 04-19-2007, 07:33 AM

I would say no, no, and no to your questions.

**SS-Power** · 04-19-2007, 01:39 PM

ok, thanks

not really a big plus. it causes the coolant to cycle too much...or so I've heard from others. I would be reluctant to do it...until you really need it. I have not done it yet for this reason. I believe it also increases emissions if that is a concern.

i thought it was worth it. i set my fan to come on at 190 and installed to 160 t-stat.runs a little cooler now

Set mine at 160, no problems here, its always better to run a bit cooler if you ask me...

to me, it is. can't really tell a difference. mainly helps in keeping detonation in check. it can run better, because the motor is cooler, which keeps the intake cooler. but this is slight. i drive mine every day.

for it to be effective, you need to have the fans set lower to match it. factory, they are set at fan #1 226* and fan #2 234*.

a t-stat is nothing more than a door. the water temp won't be any lower than what it is designed to open at.

cycle too much?? never heard that one before.

yes, better emissions comes from a hotter running engine. which is why they run it so high, to pass emissions.

I will say yes. But like it was mentioned you want to have the fans programmed to come on sooner. My average temperature is 177* cruising and around 185*-190* after beating on it on the highway for a longer period of time.

i like my 160 in the summer and 180 in the winter

i tell ya i got the SLP fan switch like 2 years ago and its great, there's three switch positions , HIGH, STOCK, LOW settings, the install is easy and its not that expensive,

even if you leave the fans on for like 5 hours they wont kill your battery

**Killer_bluebird** · 04-23-2007, 01:32 PM

BTW temperatures where taken through hptuner's scanner dirrectly from the computer as the stock temperature gauge is a joke.
