yep it has a flex fan on it, should i put a stock one back on it or just buy a electric fan to get some power back and get rid of the school bus sound it makes a bove 3000 rpms90mustangGT said:Well, not having a clutch isn't what the problem is. It probally has a Flexfan on it, which the fins straighten out at higher rpm's to reduce drag, I bet this is your problem.

no special body work. only does sometimes or if i ride at a higher rpms 2800 or higherMichael Yount said:He says radiator and t'stat are new (t'stats can be bad when new, not often though). Overheating at speed indicates that something's blocking airflow across the radiator. Does the car have any custom bodywork on the front end that may be interfering? It's probably not even possible to do it, but could the flex fan be mounted backwards? At low speeds/idle, it would likely blow enough air across to keep the car cool, but at speed, it would be fighting with natural air flow across the radiator. IN any event, the stock fan only goes on one way; I'd remount it with the clutch and see what happens.
everything is new in the cooling system i was told it was the fanPRO50SC said:I doubt the problem is the flex fan. If anything it's drawing more air thru the radiator than the stock one would. The fact that it's running hotter at higher rpm's suggests the coolant may not be running thru the radiator fast enough to cool it down, a flow problem. What is the condition of the radiator. I've seen partially clogged radiators cause this problem many times. And just because the top fins of the radiator look good doesn't mean the one you can't see are. May also be a t-stat not opening all the way.
Michael Yount said:That's why I wondered if it's possible to bolt the fan on backwards - so it's actually trying to push air from under the hood out the front of the car. If that were the case - then the fan could be causing the symptoms described.QUOTE]
Michael, didnt the new Goldwings have that - it pushed the air forward at speeds under like 10 mph so the riders legs would not get burned, but then reversed (pulled) at speed....? that did not work too hot (NPI) for that application, as i recall. LOL.
oh, where is your whole sig?
back to the thread: in addition to all that was said, i would make sure the original chin spoiler deal is on there. that thing, i think, helps to pull air up to the radiator. otherwise, air cant hit the radiator (i know that on 4th gen camaros, if that chin spoiler is AWOL, the car seriously overheats). just thought i would toss that out there.......remember in the old days when cars had those grill things.
i know you said it overheats at higher RPM's, but what kind of speed are you talking? like 4K in first gear, or does it do this at 4K in 3rd gear? (i skimmed the thread- sorry if i missed that).
good luck.

Hadn't heard that about the Goldwings. It would surprise me - Honda RARELY lets stuff like that get through testing. They're not perfect, but they are excellent. The Gold Wing channels the hot radiator air away from the driver anyway - unless they open the vents in the fairing intentionally (cold weather driving). Was it a recall/fix?
