99 was the first year for the dummy guage.

really? I have a 99 and it's not a dummy gauge...

 

Mine is. It barely registered a difference after I put in the 160 t-stat. Others here with 99's report the same thing.

mine was around 215 stock (as read by the gauge) and after the 160 t-stat it reads about 185. If it's making that much difference, I can't see it being a dummy gage...it seems to be refelcting the change in temp, not just whether it's at normal operating temp or not.

 

Hmmm, that's a first for me hearing of a 99 guage actually working. I need to get a hold of an auto tap scanner and find out for sure. Does Autozone or any of the major part stores have auto tap scanners to lend out? I don't want to pay $200 for one.

Mike hook up a scanner and compare the temps reported to the computer with the temps on the guage. You'll be shocked.

 

Not to far off topic but I have a 2000 which is def. a dummy gauge. I hooked my DigiMoto to the OBDII and it read between 220-225 from the computer in stop and roll traffic. After the 160 Thermo was put in it now the computer reads between 200 and 214. Winter time it will read around 170-185

 

I got the Predator tuner and my 160* t-stat in the mail this weekend, and just today I decided to install and run everything. (I noticed a decent power gain, BTW... good investment IMHO).

Anyway, my question is... what should I have my fan settings at?

For now, I set it to the following:

Fan #1
On: 184*
Off: 175*

Fan #2
On: 194*
Off: 185*


Is this a pretty good setting, or could it be better? A friend of mine also suggested that I should set the 1st fan to come on 10* higher than the t-stat is rated for, and then turn off 10* higher than that. Same thing for the 2nd fan, except the 2nd fan will turn on once the 1st fan hits it's max temp.

Geographically, I live in NW Louisiana, so the summers are really hot and humid, and the winters are cooler, but still humid.

 

That'll work good

 

Madz28 set my fans to come on low at 189, high at 197. Somewhere in that range will be good.

Have any of you noticed your car really running rich?

 

ok i really need help.

how exactly do i bleed out the air on a 97 formula from doing this??? i am confused on the other posts so if someone could help me with an easy way that a beginner would understand, that would be great.

 

I really want to reply to the overheating question. I'll stay out of the other argument since engine heat and hp go hand in hand.

If you put too low of a thermostat on for your cooling system it is possible for the radiator to not have time to cool the fluid. A low thermostat could never close to allow the fluid any time in the radiator. This is how you could overheat by installing a lower temp thermostat.

On some race cars they adjust for flow instead of temperature since they are expecting to drive in specific conditions. If you had no thermostat or flow control, the fluid wouldn't have enough time to cool down and you'd overheat.

 

i have a question. i popped open the cover of the thermostat, but i don't know how to hank it out. i don't want to break anything, but it seems pretty fragile, does it just pull out?
