Have recently switched from gas to alcohol. While using gas engine temp stayed around 200 now its getting around 220-230. Checked my water this morning in radiator and it was only half full.. whats the deal. The only thing I changed was fan. Had to put a plastic fan on to clear my new fuel pump.

My main question is why am I losing water????

i'd make room for a steel fan those plastic ones are junk.if thats all you changed there is no reason a alky setup would run hotter then gas

I run alcohol with a plastic fan (about 1/2" from radiator), without a shroud, with timing at 34, and run about 170 when pulling off from feature.

I run alcohol with a plastic fan, 2" from the radiator, but I also run a shroud. My cap went bad two weeks ago and lost about half the water and still only ran 190( and that is in the desert 103 heat. maybe you should check your timing and Jets.

What about the pullies? Do you have belt pullies or the kse type?

I have belt pullies, and run at 170 after feature in Louisiana where it is hot and humid. My timing is at 34, and am on the jets that came with the carb out of the box. Your cap may be bad, or just too much timing.

The plastic fan might do it but I would also look into your jetting. Alky will run so much cooler than gas you shouldnt even have a problem if jetted right.

On my older car, we run gas with a plastic fan, 22lb cap, and timing set around 36-37 and still only run 200 degrees on hot humid days in MS. I agree with the suggestion on replacing the cap.

Fixed the problem-- put metal fan on it and it stayed down. I think the problem was we had trimmed so much of the plastic fan away to clear the rons belt drive pump that we wern't getting any air to it.

Thanks for all the help guys.
