not hard at all drain the cooling system, remove the hoses, the fan shroud, the fan the drive belt, unbolt the p/s pump and remove it to the side, the alt.and set it aside,remove the acc.bracket , and remove the four bolts holding the water pump to the block clean the gasket mating surfaces. and reinstall in the reverse order. I hope this helpsHow hard is it to change a water pump on a 99 s-10 4.3L?Not too hard.



The water pump sits on the front middle of the engine. After removing the fan shroud from the top remove the accessory drive belt. The radiator fan is attached to the water pump pully with left handed threads. Its held on with a large 1 1/4%26quot; (?) hex that can be tricky to get apart. Ive used a big adjustable wrench with success before. After that its a few 1/2%26quot; bolts and hoses holding the thing on to the block.



After cleaning the gasket surfaces, stick the new gaskets onto the new pump with some rtv too keep them in place during install. Reverse removal procedure.How hard is it to change a water pump on a 99 s-10 4.3L?Nothings hard if you want to do it! Try clicking on this link:
