keep engine cool...er? nothing wrong...

[g4mbl3]

how would it be possible to decrease the temp of my engine? like there really isnt anything wrong with it or so i think (heats up quick, but when driving stays at 200, when sitting there it soaks in engine bay heat and gets to like 230 or something), id just feel better if it ran cooler... and yes i know - i have a SRI on right now, which is just my mp racing CAI shortened and im not going to put it back because i noticed no decrease in the temp of the engine, and loss of torque, so im keeping it as the SRI and may get a heat shield like on doctor speed for it. but anything else? any special antifreeze or anything? upgraded radiator? that manu. fan switch on PFYC? thanks!

Does it look like this? If so its normal with the a/c off

there really inst a whole lot that can be done... 180 t-stat... pcm modded to turn on fans sooner... intake manifold spacers...

you claim "no decrease in temp of the engine" this has absolutely nothing to do with the temp of the air going into the motor and should not be the reasoning behind not using a CAI especially when stock is a form of a CAI..

you also claim a loss of torque.. this is actually a loss of low end torque as a result of the shift in the powerband if you were to do a cat-back system you would most certainly gain a bit of the low end back and gain more up top as well...

basically a 180 degree thermostat and the manual fan switch. Other than that theres no much. You could prolly try CO2 spray kit on the radiator but I higly doubt would be even cost effective to what your wanting out of it

[GA_GT1]

id say just let it be

Why everyone is on this topic. I want to get a 160 degree thermostat in my car. My car runs its best between 150-170 degrees. Does anybody know were I could get one. And fuel milage and heat in the car make no difference to me.


My car, sometimes gets up to temps like g4mbl3 car and it runs like crap.

Speed holes!

I have a CF SC/T hood with the vents opened up and I actually do recognize a lower ambient engine bay temperature compared to stock, but it's nothing to gloat about.

Caspers Fan Switch, one of my favorite mods i have, and one of the cheapest!

How about a second opinion on what the temperature really is. The dashboard temperature gauge is about as good as the gas gauge. It gives you a rough idea not an accurate temperature.

I have a scan gauge installed and the actual water temperature is around 10 degrees lower than what the gauge says.

Check the gauge out at http://www.scangauge.com/

I found it on ebay for $160 shipped. It scans and clears codes, monitors about a dozen parameters and keeps accurate gas usage. I mounted it above the radio and it's a one wire plug and play.

that looks really slick........its like everything u need into 1 thing......

[Xplod]

I would rather stick with a stock 190 thermostat, because there is a chance of confusing the PCM with a thermostat as low as 160. In a carb'ed motor, yeah it would be fine...but in a engine controlled by a PCM?

Maybe im wrong.

[tenspeed]

The car won't be confused.

It knows the water and intake air temperatures and it adjusts the fuel accordingly. It also knows the amount of air flow, the throttle position and the amount of load on the engine.

[lvemy3100]

it wont be confused but it wont yeild very good MPG and it also will set off an SES light

if you have to change from a 195 go with a 180....

[grandillusions]

ya id do nothing lower then a 180 i just put a 180 in my girls and it still sits at 200+ but i just found out her fans dont ever turn on so now im faced with trying to fix that. make sure ur fans work. i know it sounds dumb but we are talking about pontiac and GM so if one goes out they all could go out. but im changing the relays next i already changed the coolant temp sensor. so cross ur fingers for me. btw she has the 2.4L

One for the gage and PCM, the other solely for the fans.

Check that out as part of the relay analysis.

Good luck,

Check the Fan Relay, the Thermostat...etc.

[grandillusions]

the themostat was changed and the coolant was flushed and new was put in. and ill check my haynes manual for the 2 sensors. but ill be changing the relays tomorrow when she comes home from her parents house in mississippi. so ill let you guys know. i also plan on jerking out the fans and testing them as well. rick any other ideas ive been watching the threads on problems and u seem to know ur shit so help a brother out lol.

[ENGGUY]

Altering the operating temperature on an engine controled by an engine management system changes the calibration of the sytem. So by changing to a nonspecified thermostat, you are fooling it to belive the engine is cooler. Thus things like the timing curve could be changed, and fuel trim. Just not a good idea.

hey man i looked in my haynes manual and it only talked about 1 coolant temp sensor. so im guessing thats all lol. but ill post up if the relays help. hopefully i pulled some good ones from a junk GA.
