My dads needs a new water pump for his '83 Silverado v8, anyone have a DIY or a schematic or know of where I can find one? Maybe someone could tell me how. He's pretty handy with cars just doesn't know what needs to come off and in what order. -Thanks in advance!
Its an hour job tops. Take off the alt. and alt belt, and bracket Same with power steering pump Take off the fan Take off the lower rad hose from water pump and the heater hose from water pump. Take the 4 bolts out of water pump thats holding it to block. Clean the gasket area Put new gaskets on with new pump, bolt back in place. Put the things you removed back on Heck the only tools you need is a straight head screwdriver, 9/16, 1/2 and 7/16 socket, and a ratchet,
I just just put a new water pump on my 2000 silverado. You do not have to take the radiator out, just be careful not to ''poke'' any holes in it.
ok, this is every little step you could imagine, in detail, with reasons for doing it as said, in the order ive put it down....negligence on my dads part has caused 2 waterpumps to crack in the winter due to lack of antifreeze, because we just put straight water in it, because the radiator is cracked for the same reason as the waterpumps.(but the block luckily hasnt cracked) remove the fan belt, and lower radiator hose, to drain the radiator, and get the belt outta the way. if its a smallblock, you remove the fan shroud, remove the fan and fan clutch, then remove the 3 bolts on the left, and 2 bolts on the right, after youve drained the radiator. once youve removed the 5 bolts, pull it out. wrap a cloth around 1 of the 4 studs on the waterpump, and take a pair of pliers to break it free, repeat untill all 4 are loose. remove the studs, and take the pump with you to autozone so you can get a core charge. scrape the mounting surface clean(dont get anything in the block). install the studs, and have a cloth around any stud your working with when you use the pliers to tighten it down(to avoid damaging the the threads.).apply silicon gasket sealer to both sides of the gasket, and put the gaskets on the block. quickly put the pump back on, and put the top bolts in for support. put the other bolts on, and tighten to about 10ftlbs minimum. slide the fan pulley onto the studs, and put the fan back on. put the nuts back on, and tighten as tight as you can get them, itd be terrible for the fan to go through the radiator. put the fan belt back on, put the lower radiator hose back on, and put the fan shroud back on, in that order. wait an hour for the silicon to dry, and fill the radiator with the motor running, and go for a testdrive
remove the fan shroud , then the then belt, then the fan. drain coolant then remove hoses from pump. then the water pump .. it is a 2 hour job at most . can be done as little as a hour if you have the right tools and understand the job. you will need special too to remove fan. rest is 10mm 13mm , 14mm or 15 mm bolts .. press clamps need pliers or flat screw driver to remove clamps .
