A good assortment of extensions and wobbly adapters. Put some grease on the water pump oring to keep it in place while positioning the new pump.

The O-ring is the seal between the pump body and the block or timing cover. You use grease (silicon grease will work) to hold it it's the channel (I can't think of the proper name) during assembly.

Drain radiator, remove fan shroud and fan(special tool for fan clutch removal) remove WP pulley, remove belt tensioner (be prepared to buy new belt tensioner if at the end of adjustment) Some may remove power steering pulley to unbolt P/S pump to pull aside, I don't. I just remove #1 intake manifold bolt and roll pump out after removing bottom bolts with special wobbly socket. Make sure you loosen the 19mm bolt at the center of the tensioner before loosening adjustment or simply stretch the belt over the pulley to remove as not to touch the adjustment on the tensioner.

i had to pull the power steering pulley and partially unbolt the p/s pump to get clearance to pull the old water pump out. I have done this three times over the years.... it is going to take 5.5 to 6 hours... toughest bolt is under neath the pump closes to block.... that one takes the wobbly...and you will have to tape the wobbly so it does'nt have too much play. search may help you identify the tool
