anyone know how hard or what steps or what tools are needed to change a waterpump on a 1990 crown vic station wagon

coolant is leaking in my car but nothing is dripping and when car is idling, nothing drips or sprays as i went under the car and above and saw nothing. there is coolant around waterpump area behind fan and on sides and undersides of engine casing so i will go with the waterpump?

Check carefully where the manifold and block meet. They seem to like leaking there as well.
Any water staining around the weep hole in the bottom of the water pump snout?

Alex.

I agree, check to make sure it's not the intake manifold gaskets before you try changing the waterpump.

I changed the one in my 91' this past summer. There's a lot to it because of everything that's in your way. I took pics that I can post up if you'd like to see what your in for.

Pre-soak all the bolts a lot and be very careful with the waterpump bolts(you reeeeally don't want to snap one). They are all different lengths and need to be kept in order.

Yea, they also like to be very corroded and snap off in the block.

Yes.

Also, the studs that hold the power steering pump bracket need to have two wrenches on them - One on the movable nut and one on the nut permanently affixed to the rod.
If you don't, the whole rod will come out and crack the bracket.
This is not good. Try finding another one of those from a non-junkyard source, I dare you!

Well, I guess I got lucky, I didn't even know about that going into changing mine. Although I probably would have stopped if I saw the nut taking the stud with it as I turned it (I hope). But I sprayed stuff down days in advance before starting the job.

Here are some pics I took during the job. This gives an idea of just how many things are tied in with the waterpump




Here you can see I have the waterpump bolts laid out in order.


New pump in place

When my water pump died, it was very obvious because coolant started shooting out of the weep hole on the bottom when I shut off the engine at a rest stop. When it was running, it wasn't leaking much and temperature was normal.

Weephole is on the bottom of the waterpump snout.

You need to remove the fan clutch, fan shroud, unbolt the brackets for the a/c and lay it to the side, undo the power steering and alternator brackets and lay them to the side. Then you have full access.

There is a good amount of work involved, but it isn't that bad. I took mine off in about an hour (or less) taking my time. At the same time mine had a lot of grease and grime built uo around it!
