Hello everyone,
I removed my non-working fan/clutch and installed an electric fan. I then put the pulley back on and used some shallow bolts to secure it. Now the pulley doesn't rotate and makes a loud squealing noise. What have I overlooked?
Thanks!

Maybe the bolts aren't shallow enough?
Loosen the belts again and try spinning the water pump pulley by hand, it should turn very easily.

Thanks. I'm going back out to work on it again. The bolts only have about 1/4 inch of threads going in. I wanted to take pulley off to see more clearly. But I couldn't remove the pulley completely. You have to take off crank pulley in order to have the clearance to remove this pulley.

So I put spacers on bolts, which only allowed the bolts to have about 3-4 threads at the end. Now it works as it should. I'm stumped as to why the longer bolts caused the pulley to seize up, but the shorter bolts allows it to spin like normal. I love it when I find a solution, but hate it when I don't understand what caused the problem.

That’s what happened to me. I had the same issue. Found out that my bolts were too long. Had to replace the bolts with some shorter ones.

The longer bolts were hitting part of the pump housing.

Thanks man. It certainly is nice to know that I'm not the only one that had this problem.

Thank man. At least now I know what the problem was.

You were right! Thanks!
