Overheating

[azkikr10]

Okay guys, I've been reading threads for the past week but nothing seems to help. My car gets up to 235+ coolant temp sometimes cruising on the highway. Things changed so far:

Thermostat
radiator and cap
2 slim fans
flushed coolant with 40% 60% distilled water coolant and watter wetter
Fan does turn on but the ac fan only comes on when the a/c is on. I've had my fmic for over 3 months and just started overheating within the past few weeks. Car also seems to warm up a lot faster than before. No cooland in oil or oil in coolant. Any help would be greatly appreciated.

check your radiator or front mount for being plugged other wise you may need to flush radiator or even buy a new one because it could be plugged inside with crap also if you replace it maybe replace it with a aluminum radiator because of the front mount but this is just a suggestion and maybe it would help but good luck to ya.

check your vaccum hoses. it might be bad, and not getting the pressure to where it needs to go. i have had problems with other cars having back vacuum and overheating.

check both the lower and upper radiator hoses...as this seems to be the only thing that you overlooked. The upper radiator hose is for the return path of the coolant, and the lower hose is for the inlet route to the block. Sometimes air bubbles get into the lower/upper hose and create blockages, where there is a massave block of air and no flow occours. good luck man

Did you replace if woth a stock one or an after market one? The FMIC does block air flow to the raditator

Make sure your fans are set to the correct direction. In front of the radiator, push. Behind, pull.
Run a compression test.
And check the Tech Guide, Engine section for a troubleshooting overheating article... Whoever wrote that article is awesome....

This was from last September. If the original poster doesn't respond soon, I'm closing this one.

turns out one wire came loose from one fan so that was the problem.
