I got the bolt out with an impact wrench. Came out easy, one trigger pull. Now I need to get the pulley off, seems stuck. Any suggestions? Help?

It is probably stuck on from years of heating and cooling combined with plain old rusting into place. I believe that you need a tool like this one: http://www.autozone.com/test-scan-and-specialty-tools/harmonic-balancer-puller/comp-cams-two-in-one-harmonic-balancer-puller-and-installation-tool/892664_0_0

The good news is I think AutoZone will rent/loan it out.

I am using a pulley puller. Got it about 1/2" out. Think I need a larger puller.

Yeah from what I can find out it should come out with the pulley puller. So it is definitely possible that you just need a bigger one. Or maybe you can substitute something in to use as a spacer, effectively making your puller bigger. Probably safer to just get the bigger puller though.

I got it out with the 8" pulley. Put the water pump in and now am having some trouble getting the timing belt back on. Have all the marks lined up and clipped. Have the belt on the crank pulley and trying to get it over the tensioner pulley. Took the tensioner back out and will retry to get the belt and tensioner back on. Very little slack in the belt.

Hello,

Make sure the new and old belt are the same size. The belt should go on without too much trouble, it sounds like you may have got the wrong one.

Please let us know what happens.

Cheers, Ken

I got it on with a bunch of pulling, a pry bar on the tensioner pulley, a little rethreading, a few tightened here and there. Got the pulley bolt in finally. Feels snug, marks in the right spots.

Any tips on getting the crank pulley back in? It's a heavy beast with a thick bolt and coarse threads, has a keyway. Thanks for the help.

Hello,

Yes, put the pulley in the over at 200 degrees F. Once warm it should go on the crankshaft easier. You will need gloves to take it out of the oven and to install it back onto the car.
