got a quick question about the water temp. its kinda dumb but I honestly dont know the answere, so please donnot flame or bash thread.

I know that their is a optimal temp for your car judging by the temp guage, now my question is; is it possible to run to cold ?? Because tonight after driving for an give or take and hour my temp needle hadnt even budged. Now I know it works because when I cut the fan off the temp guage rose a little. Any help would be appriciated cause I really dont know the answere haha,
thanks, dory

 

Your thermostat could be sticking "open" in not allowing the vehicle to warm up to operating temp.

 

yeah thats pretty much the only way you could run cold. Now running too cold and running too hot are both bad. If you vehicle doesnt get up to operating temp that will affect your ecu and its readout. Since most everything is electronic in cars these days, alot of the instruments used are based off of your engine's temp. Say for instance in a start-up situation. Your computer runs in what is called open loop. What that means in that for the first 20 mins or so you computer will open the injectors up about 30-45% to help the engine warm up quickly. This is usually noted but the high rpms when you first start the car. After that time it will switch to closed loop, running normally at a normal idle. So "running cold" will affect ur gas mileage because the computer is giving the engine more gas trying to warm it up on top of you hitting the accelerator during normal driving. Running rich or with too much fuel in the cylinders will not only affect your gas mileage as stated earlier, but it will mess with your emissions as well. My vote is to get that thermostat looked at as soon a possible, gas is too high for that...lol... LiveOne

 

yea true, Iono I mean i really only noticed it after installing the new radiator. Because further thinking, its and after market fan and a decent sized aluminum radiator. So i dunno, but yea I will check out the thermostat. Thanks

 

I don't think that should matter, the thermostat should do it's job regardless of what setup you're using.

 

Are you reading this of the factory 240 gauge?

Those gauges are retarded and are known for malfunctioning before the sensor goes bad all the way.

If you're going from an aftermarket gauge that you know is accurate then you should be between 170 and 180 F at operating temp on a SR. 200 would be running hot, people say they hit 220 on a hot day at the track, that is bad though.

 

by that you mean a factory 240degree gauge ?? if so then yes

 

Dan said the guage in his hatch worked a million times better than the aftermarket one in there. But I don't know which one was in there.

 

The factory gauge reads "normal" as something retarded like 140-215 or something completely ridiculous. It has no numbers on it and basically warns you of overheating after it has happened. Getting a legit temperature gauge is important.


Dan may have meant the sensor was way better then the aftermarket one he had. This is true, the stock sensor is awesome, they just have it wried up to a shitty ass gauge. Greddy has a multi reader thing that lets you hook a gauge up to the factory unit - it is incredibly accurate. Yashio Factory does this too but with a digital gauge (even better). You can get a Yashio Factory one for around 80-130 bucks.

 

Oh. I don't remember exactly what he said was a piece of shit.
