In the Bentley manual, one of the = steps for replacing the head gaskets is remove the crankshaft pulley. What = is the reason for this? Is it to remove the coolant cross-over = pipe? Are the special tools requiered to lock the crank or can the van be put in = gear and chock the tires?

P.S. I will be going to Campbelltown, PA and hope to = meet Ken there.
