Could there be such a thing as running TOO cold?
just a thought i was having while sitting in traffic. i know cars have nominal operating temps, but with our (or at least my) obsession of keeping underhood temps down i was wondering if it were possible to have the car running below nominal temps.
my car has a vented hood, water wetter added to the coolant, manual fan control, and the more air-flow efficient 99 front end. but i have the stock radiator. what would happen if i were to throw an after market radiator into the mix?
thoughts on this? or am i off my rocker....

I thought there was a certain temperature engines needed to run at for optimal performance, mind you, it probably can run below ths temp without damage but I figured it should be held at that "just right" temperature. Its not the magical number for all cars, but im sure its a range.

yeah dude, you're a little neurotic, the only time when you're going to run too cold is during your warm up period. and id never thought i'd see a thread like this in the third gen section where im supposed to be reading about people overheating thier motors from idling... geesh
and sorry for the thread hijack but im a newb and dont want to start a new thread. what temp do you guys with the manual fan switch mod flip it on? and when is the terminally highest temperature you can operate at, as in as high as you possibly can without damaging the motor

I have a manual fan switch. I flip it on at 70C and thats when I allow myself to get on it (double throttle plates and accel warmup removed). Dunno what that is in F.
On a side note, a correctly oporating thermostat wont allow you to run "too cold." It'll just stay closed till it gets warm enough, open, cool down, then close back up.

Say you have your fans on well below the tstat opening temp(below 80C). What if you engine coolant is way hotter than the radiator coolant? If this happends will the Tstat not open for circulation and cause engine failure?
I would personally say setting the fans to go on when the tstat is fully open or just slightly before Aprox. 95C? What you think?

Fans cool the coolant in the radiator. They have nothing to do with the t-stat. The engine heats the coolant until the t-stat opens. When it opens, it allows cooler coolant to enter the engine.
Turning your fans on at a certain temperature is a matter of choice. I like to make sure that I turn them on well before I reach my destination. This ensures that the engine temps will be as low as possible when I shut the engine down. I also like to keep the coolant temp under 210, so I will turn on the fans accordingly.

Although it's fun to see people posting when they're trying to remove them for the first time.
