There is a secret to doing these that not many people know. You can buy a special tool from Snap-On called the FLX-13. It will get to all 3 of the 13mm bolts without taking any other part loose. You can leave the tensioner and the P/S pump in place. There are two secrets to taking it off. 1. Take off the two clamps on the small by-pass hose and slice the hose off. 2. Take out the 13mm intake bolt that is under the front side. It will be the first intake manifold bolt you can see on the bottom front. The pump will then roll out. I can do one in under an hour start to finish when I feel up to it....This is with my $40,000 worth of tools though. (And shop air for air tools)

For the o-ring that goes in the bottom use a dab of grease to hold it in place then smear a little on the block where it will slide together. Never use a sealer where there is an o-ring. Same goes for the thermostat. Replace it tooo. We have the parts!!!!
