Thanks for that, I have got the belt and idler off now. I got the pulley off using a generic puller for GM Harmonic balancers. It's not on a taper, it was just a little tight because of some rust on the shaft. I'd like to change the front crankshaft oil seal while I have easy access. Do you have any tips for getting the crankshaft timing pulley off? It doesn't have any holes to bolt a puller onto.you have to take off the front motor mount. Put a piece of wood under the oil pan and put a jack under it then take off the mount.
