Question about 1995 Pontiac Trans Sport
I really can't afford to bring the van to a shop, and I've done quite a bit of simple car repairs before. Before I start on this one though, how difficult is it to replace the crank pulley and are there any tech points I really need to watch out for? Such as anything that could get hung up, out of balance, or damaged that I would have to worry about, or is it basically like replacing any other pulley in the system?

The pulley will be either pressed on or bolted on
if pressed on you will need a harmonic balancer puller to get it off and space to swing a hammer to put it back on
if bolted it will be torqued to up to 90ftlb so holding the crank to undo the nut is a problem so get a 1/2 " impact gun for the job
you will need space for the tools so look at what has to be removed first
next there is a crankshaft position sensor behind the pulley so be careful with wires in that area
some engines have the pulley bolted to a crank hub with 3 or 4 small bolts in which case the job gets simpler
the item to watch out for is the drive key in the crank shaft as it can fall out of place and fall inside the seal especially when refitting the balancer

After checking around, I decided to replace the harmonic balancer. I had a repair shop fix it for me and I think they over charged for the part. But, at least I'm on the road again. This Grand Am has 227,000 miles and still runs pretty good.

Haven't laid eyes on one of those for a really long time!!! If you can't get info. you can do it the really "non technical way": stand next to it and eyeball the pulleys...Especially with the belts on, it's easy to tell if you have them aligned properly (don't have to tighten them up, just enough so they are in straight lines.) You would be surprised at how accurate your eyes are!!!

Check all of the accessories that run off the belt. some may have loose or bent pulleys or the acessory itself may have come loose. Be careful to route the belt exactly as shown too. Tighten up or replace your wobbly pulleys.
