Default 87 3.8 lesabre water pump

Hopefully this is the right forum for this. sorry if it'* not.

I have a friend with an 87 buick lesabre and his waterpump is shot. It looks like it would be a pretty easy job to do. It looks just the same as the onld bonnie 3.8l engines. I just have a couple of questions. It doesn't look like the engine mount goes around this water pump. Am i correct? And did they also use that crappy plastic intake from the waterpump into the engine.

It looks like all i'll have to do is take off the alternator, the waterpump pully, then the waterpump. I think it will be easy to do, but i just want to make sure.

Thanks in advance.

There is no engine mount around the WP and you should not have to remove the alternator. And this car does not have that "Crappy Plastic Intake". Just drain the coolant, remove the serpentine belt, remove the hose from the WP, remove the pulley bolts, remove the pulley, remove the WP botls and then the WP, scrape off the remains off the old gasket as best you can, install new gasket & WP. Torque the WP bolts to 29 Ft Lbs. If it'* been more than 5 years you might want to replace the hoses too at this time along with a new thermostat since you already drained the coolant from the system. Good Luck.
