Replacing the water pump is one of those repairs that took a few hours for this 1st time for me, but I can see it being much faster next time. Some bullets that come to mind after replacing WP this weekend.
- the symptoms were increased noise in the pulleys, at first thought it was AC clutch bearing but turned out to be the WP
- existing WP was only 4 years and 26k miles old saab oem, not reasonable IMHO
- recommend loosening the 4 or 5 pump to pump body bolts before removing the 3 bolts holding WP to block
- the work of removing wheel and shroud to compress belt tensioner can be avoided if you have a long thin 19mm wrench like the SnapOn which allows compressing tens from up top and placement of hold tool
- removal of WP pulley was done before removal, loosening 4 bolts is easy with two opposite working wrenches, tightening I used a long fairly heavy screwdriver to hold pulley while wrenching
- access to turbo coolant line banjo bolt was from right side of engine bay with 2 or 3 extensions
- shoving assmbled WP into the small and large oringed pipes was a bit of a leap of faith but worked out fine with vasaline lubed orings, I did not remove the inner piece which requires 2nd large oring (seems ok not to ?)
- turned out the existing hose clamp at WP for large hose to radiator was crap and caused coolant dripping after I was done, had to go back in remove AC comp again and replace with a new wider stronger hose clamp (should use a new clamp for this location)
