SES and a tstat?

[zeetwentyeight]

Will putting a 160 or a 180 Tstat make my SES light turn on?
Will i need to get a tune to run one to not have the light turn on?

It won't throw a code/SES. If you want the fan on/off temps changed, that would require a tune.

Cool do you think i need to go with a hyper tech or can i just go with a usual 180 degree stat?

[zeetwentyeight]

Is this good enough?
or do you think i should stick with hypertech?

I've had a hypertech 160 in mine for years with no issues, don't know about that one. Are you needing to replace yours or just want to change the opening temp? Reason I ask is because my owners manual says 180 is stock, not sure if the '98's are a different temp.

I hate hot running cars its running at like 213 and my stat opens at 190

[98maro]

My car temp goes higher than 200.
I dnt like that

I would'nt put a ton of stock in the factory guage... They are usually junk from day 1... 213 on a factory guage = "warm"....

getting a tune for the fans makes the t stat work like it is supposed to. if you put in a 160 t stat with stock fan settings keeps the t stat open with no fan help with the cooling. i put in a 180 and the first fan opens at 175 and the second opens at 185 and as far as hptuners shows on my logs it hasnt gone higher than 189.

So the only way to keep the temp under 200 is with a tune?

Yep for speeds under about 35 mph, you'll need the fans on and off temps adjusted. Above 35ish, there is enough airflow to through the radiator to keep it cool

213 is not hot and is nothing to worry about.

From what i hear the 98's have a three wire harness so it reads alot more accurate then the newer ones

[sjsingle1]

is the stock stat 180 ???

[zeetwentyeight]

Around 190 or just 190

[sjsingle1]

i read in some reference material that it is 180

[zeetwentyeight]

From what i have picked up its 190 from what i have heard anyway

[Cutlass]

It is 190. I don't think any manufacturer would put a 180 t-stat in for the sake of engine efficiency(fuel economy) and exhaust emissions. Engines run more efficiently at hotter temp

[cammed goat]

Mine was tuned and the fans were adjusted with HPT. I dunno if the replacement waterpump came with a 160, 180, or 190.

But it is better to have a lower one right?
