Somedays yes.. others of us buy inspection mirrors after pulling out all our hair and getting refused help by the local woman with small hands.

Glad you found it..if you need any other assistance or procedures to replace it..just holler.

Ok..

Step 1, hand hubby a beer.
Step 2, put on work gloves..you are getting dirty
Step 3, Next beer for hubby..he'* a thirsty guy.

Seriously though
You'll need to support the motor and remove the bracket in front of the waterpump.
Remove waterpump pulley
(Not sure if you have to lower the power steering pump on your year...if so.. unbolt the 2 13mm bolts through the holes on the pulley and let the pump rest genty..be careful..the oil pressure sensor is right under it.)
Remove the rest of the bolts on the pump.
Clean gaskets..
Reinstall

Easiest way is have a mechanic with experience do it.

The slightly harder way that ends up costing more usually is to get some dye/sealant and put that in..then fill with freon. Once you find the leak.. let the freon back out.. fix the part and refill with freon.

Cool the water pump isn't as hard as I thought. and all it'll cost is the price of the pump and gasket and a 6 pack of michelob lager or maybe 2 6 packs

I think I'll have hubby get a hold of his buddy to come over and give me a hand. Hubby can watch the kids.

Won't be the first time I worked on our vehicles.
Lets see I've done:
explorer-starter
bonneville-alternator and belt,
f150 wiper motor and vacuum lines, tranny pan gasket and filter,
those are a few things I have done

I feel better when I am working on cars

Hubby has problems admitting when I know what I am doing

I'll keep you updated on the repairs
thanks for all help

You will find the mount blocking the water pump to be a pain to remove. Because a stud was used instead of a bolt in the topmost mounting hole, the portion of the motor mount on the frame rail will have to be loose or come out as well. Take the stud out when you can and go to the hardware store and get a matching high grade bolt. You'll be glad you did if you have to take the motor mount off again.
