I have a 1994 Fuel injected 460 V8 7.5L on an F-super duty chassis. I found the water pump to be leaking from the weep hole. I decided to change it myself.

I have taken everything that may be holding the pump but it still will not come off. Took the alternator bracket and A/C compressor off, power streeing pump off, belts, fan & clutch off. Access is pretty difficult but I am sure that I took everything that I see off.

Any ideas why the pump still feels that it is rock solid on the block?
Also how do you keep track of where all the bolts that came off go?

Any help or advice would be greatly appreciated.

Not sure if this will help you any but its the instructions for a 96..

If you are sure its completely unbolted it could just be siezed to the block due to rust. You might have to give it a couple good raps with a hammer to break it loose. Also be mindfull that some water pumps have a flange where they seat INTO the front cover so dont go too wild with a hammer. Look at your new one to see how it is designed so you can tell if it mounts flush or not. If it is flush mount and all bolts removed give her a good pop or two.
