Water Pump Tasks ahead

Question all.

How hard is it to replace a water pump on the 4.5 Engine (89 Coupe)? What steps are involved and about how long does it take? Is it a "B**ch for lack of a better word. :)

I have done replacement before on a good ol' Lincoln V8, but this seems alittle more buried.

Any info appreciated

Thanks

I had to jack my engine up one inch to get some clearance. Some tech posted here a couple weeks ago that they unhook one or two motor mounts on every 4.x that they do and jack it up a few inches. I think that might have saved me some time and I may look into that if I have to do another one. Make sure you have the correct torx bit. A lot of people seem to strip them, but I don't see how because the bolt head is pretty stout. I assume someone at sometime used the wrong bit. Beer and patience are essential because it is a frustrating tedious task but very doable for the average mechanic.

I need to do my 92 Seville water pump and figure I'll do the chain at the same time. Does anybody know the size of that torx. I tried to tighten them down when my pump was leaking and couldn't find one in my collection. I ended up just inserting the closest one I had and tilted it to where it got a little bit of a bite. It stopped leaking. I'll go buy one, if I know the size. The book doesn't say ... only the torque value.

I did this job in a walmart parking lot on my 88 Eldorado. I was lucky that day since I had a spare water pump in the trunk. It took me about 2 hours start to finish and that included buying antifreeze and water to fill up the radiator. The hardest part is removing that torx screws and yes, space is very tight.
