FMIC install now car over heats.....

[dnhieu]

alright i installed my fmic about a week ago and the car keeps getting hot. i first installed 100% water and 1 12" slimline fan and it got hot. i then called up sb and ordered another 12" fan and wetter water and its taking longer to over heat up its still getting hot. i dont know if the water pump is bad but when i start up the car when its cold and open up the radiator cap it seems the water isnt moving as much as it does in my other talon. so im running 100% water, 2 12" slim fans, 1 bottle of wetter water. i still have my a/c and the bumper is still un hacked. both fans are comming on.


thanks in advance

Please, put antifreeze in there. Not only is it a lubricant and doesn't boil as easily, it also is non corrosive, unlike plain ole water. I had a 1989 Dodge Dynasty that we bought used in El Paso Texas. The timing belt went on it one day and being poor I didn't put anti-freeze back in since we were in a desert. I figured it wouldn't hurt it and instead ran straight water. Within 2 months after doing that a hole had rotted through one of the freeze plugs and pissed water everywhere. That was NOT an easy thing to fix with the engine in the car. Do what you want, but I'll never run straight water ever again.

Finally, I have a question. I thought antifreeze cooled better than straight water. Doesn't it have a similar ingredient to alcohol, giving it a cooling effect?

I'm pretty sure it has the same cooling properties, or specific heat for you chemistry people, as water however it has a higher boiling point than water so when mixed with water it raises the boiling point of the water. That is why an engine can reach over 212 degrees and the coolant not boil. Well that and the fact that it's under pressure which also raises the boiling point. That is why people get high pressure radiator caps.
