OK, someone else on here has to have some of these problems. As you all know, I have a 1993 Vulcan. My problem lies in that my engine ALWAYS runs hot. It has been around 35 degrees here, and I have the heat going up to the N, and then the electric fan comes on, pushes it back down to O, and then repeats. In the summer, I even have it stall sometimes from the heat, and then won't restart for a while. I have a normal radiator, unclogged as far as debris, fairly new coolant, a big tranny cooler, and regular non-ethanol gas (the ethanol seems to make it worse). How can I fix this? I don't feel safe taking it on trips because of this, and its a pain in the a**.

P.S. - I have followed the Ford Service Bulliten and replaced the TFI sensor. It is mounted on the throttle body, and was known to go out quickly because of excessive heat, causing problems. I now have the new and improved version, so thats not it.

P.P.S. - Also have a new fuel pump from Ford, factory type, so I doubt that is it either.

Thanks all!

Well, asuming the temp sending unit and thermostat are both good, I'd look for someone with one of those hand-held laser temp gauges. Then, see just how hot it's really getting. Maybe someone you know that services A/C units would have one handy.

The sending unit and tremostat are both cheap replacements for the do-it-yourselfer. Don't forget, the rediator cap must hold pressure up to somewhere in the 13~16 psi range. If it don't, it won't cool properly.

Yes check your radiator cap. Do you still have the air deflector mounted below the radiator?

ethanol gas has not a damn thing to do with overheating,
i bet ur radiator is crap or junk
time to get ur creditcard out and go to www.radiatorbarn.com and order a new one
they are great and also have lifetime warrety
and are made better then the factory ones meaning the one i got is a replacement for stock and is made with poly plastic tanks and not regular plastic tanks, so bascally their reinforced
