I have looked all over within the city that I live within which is Mesa, Arizona and it has been a very hard task. The size of the engine is a 4.3 liter engine I need a some sort of diagram or repair manual on how to change out the Water pump and what I would need as well how the process would be done. I also have problems with the passenger side door speaker that I would like to replace too, I don't know how to take off the cover around the speaker as well. I've checked at Checkers, Autozone, Pep boys and I have not been able to find anything that seems to help. I don't have much to be able to buy the manual online but just looking for a way to fix my truck. If anyone has any suggestions please help me if you can. Thank you
