thinking on replacing the manufacture fans and installing a high-performance set...any input will help...

 

If your car is overheating with fully functioning OEM fans...aftermarket isn't going to stop it.

 

when are you experiencing overheating such as conditions? have you checked the coolant temp sensor? i assume by everything you mean you have changed the thermostat, radiator cap, flush and refill and checked the radiator itself?

 

check the following. coolant level, radiator cap, thermostat( by seeing if the upper radiator hose gets hot when the fan turns on....this indicate the thermostat is opening at about 180 degrees farenheit). Check the fans. If everything works out try bleeding the system to remove any possible air pockets

 

Only on the hot weather days and as long as i drive around 70 mph is fine the problem is when i push it to speeds over 80 mph.

 

Take the car to a car wash and wash down the radiator and ac condenser. The helped a bit on my old truck. You be suprise how much dirt and other crap are on the radiator fins. If you have a steam cleaner that would work even better.

 

Am I missing something?? or partially closed thermo.

 

Wow how about also take that ugly a$$ pic out of you're signature. It could be a number of things, but maybe letting us know what you have already done would help out a bit.

 

lol, not to hijack, but man check my overheating thread and read from there.....i did all that and STILL overheating....good luck

 

well... since we're talking about cooling systems....

does the cooling system contribute to our MPGs??
