1998 Volvo S90 - Water Pump Replacement and Timing Belt Inspection

In addition to replacing my struts this weekend, I also replaced my water pump due to a leak that caused me to top off my coolant once every two weeks or so. In order to replace the water pump, I needed to drain all the coolant and remove the timing belt to access the pump. Since a timing belt in bad condition can greatly impact your engine performance, I inspected that as well to ensure no cracks or broken teeth. Its condition was good, so there was no need to replace it. To replace the water pump, I needed ratchets, wrenches, and screwdrivers. This work was performed off and on over three days totaling approximately seven to eight hours of work.

    Original owner of volvo v90 1998 and it's time to change the water pump for the same conditions you mentioned in yours. Question: is it possible to remove the timing belt tensioner only to open up the access for the replacement? In this way, I would not have to play with the timing belt teeth position after the pump r&r.
