Radiator question - engine temp running very cold with heat on
OK so a few weeks ago some anonymous asshat decided to remodel my front bumper, lights and hood on my Integra (another reason to drive a beater Shawn. )
Anyway, there was no damage to the radiator but today, with the cold temperature, I noticed that if I turned the heat on, the temperature gauge dropped down to about 1/4 up from the coldest setting on the gauge. If I turn the heat off, it returned to almost normal, between 3/4 and dead center. It's run a bit colder on the temp gauge than it did prior to the mishap. I guess that's due to the extra air getting under the hood.
My question is: Is it bad for the engine to run too COLD? Obviously too hot is bad, but what if the engine temp is too cold? Any problems with that?
Keep in mind this was after about 45 minutes of highway driving, so the engine was well warmed up.
I replaced the radiator hoses last summer and I bought a new thermostat which I never installed. Think it might help to install the new one?
Thanks.
Neil

So I guess my question is what is the worst that happens from running the car too cold?
Thanks Steve.

The ECU would set the check engine light if it was too low though, regardless of what the gauge shows.
