i know that running the engine cooler is good. but, if i don't have any problems with overheating and i run it really cool, would this do more harm than good?
i have a mugen radiator cap and a modified thermostat. no problems with overheating even with the factory radiator cap. what i was thinking of doing is flushing out the cooling system and adding the redline water wetter to make it run even cooler. if anyone has any experience with this let me know. thanks

 

If it's not overheating I wouldnt do anything to it. the water wetter wont make it run any cooler then the thermostat anyway.

 

U know this is a good question, I have the same problem during winter, when I am on the highway, the temp goes down to past the C(cold) mark, usually it is late at night and I am blazing a trail to go home. I wonder if this can be damaging to the motor or anything else

 

have you replaced your thermostat? it's probably bad. If the thermostat is working properly you're car wont cool off even if it's freezing outside.
