How hot can aluminum heads get before they warp?

08-04-2001, 02:16 PM

The car was hot and I left the ignition on so that the fan was running, to try to cool the car down, and was leaning over the front of the car looking under the hood. I felt a very light breeze coming from in from of the grill, very light(didn't think too much of it at the time). Days later I was thinking about it and took a thin piece of cardboard and eased it between the fan and engine. It would blow the cardboard towards the engine until it got close to the center of the fan and it would start pulling it. The dang fan was blowing all that engine heat right into the rad and I couldn't go 15 miles without it boiling over. We checked to make sure it was wired right into the car and it was, but it was definitely blowing the wrong way. We dropped the fan and I opened the little box on the fan I switched a couple wires and presto the fan was blowing the right direction

. Funny thing, I got the fan cheap because the guy said he didn't like the fan

.

I was getting advise from everyone around here, my mechanic, mechanics at work, anyone.. I got advise like "must have air pockets" "maybe you have a clog somewhere" "have you checked the heater core?" I have a bald spot from scratching my head trying to figure it out(heeh).
