and there's alot to remove to get to the water pump.
Fan shroud; poly-belt; viscous fan clutch; fan pulley and a few things I probably forgot. The timing wheel must be removed; loosen the nuts, then gently work it forward (from top and bottom) until it slides off. Then the remainging bolts on the water pump can be removed.
Also the little 'L' water hose from the Tsat: while you're in there, consider replacing it with 80C version. Can't hurt.
