replace water pump on 1998 park avennue ultra super charger
I have the side motor mounts loose and the engine supported, but I cannot get the motor mount out of the way to remove the last two bolts on the water pump. What am I missing?

I'm not sure what problem you are having... we do have this small writeup on the SC engine.

Get them loose, pull out the pump with the bolts still in, get it at a bit of an angle, now you can take the bolts out of the pump. Be sure to do the reverse as you put the new pump in.

Parts tip, if you have not bought it already go with the more expensive water pump, it comes with an aluminum framed gasket.
