Water pump how to replce

Drain the radiator Pull the belt, the fan get to the water pump and start to un bolt it . Scrape old gasked off put new gasket on bolt back up same order it was taken off

The only problem is we didn't take it off & we tried to buy a book but wasn't able to find one. Do you have any suggestions

look, just get a mechanic to do it- come up with the money- if you do this job, and have to redo it- you will wish you had just listened to this advice-
