Water Pump Replacement Issues

[Krazykid]

Ok so I found the folllowing link for a DIY. (pretty good overview of what I am getting myself into)

http://www.dieselbombers.com/chevy-...rum/15967-lb7-water-pump-replacement-diy.html

But my problem right now is how to hold the fan clutch pully still to break the 1 7/8" nut loose. I can not find anyone in the upstate of SC that has the proper tool to do this. (for sale or loan)

So, my question is what do most of you guys use to achive this removal? Also is there anyone in the area that might be able to lend a hand with this?

i used a flat punch on the left side of the bolt, couple good hits and it freed right up.

Thanks for the insight, the flat punch goes all the way through the pully? and which way is the nut threaded?

Put a wrench on the nut and give it a couple wacks with a hammer. Should spin right off.

i used the punch on the nut, the left side of it at a bit of an angle. when you hit it, it will help break it free. its normal thread.

sorry i was very vauge in my first post.

Thats how I did mine, might take more then a couple wacks of the hammer but 99% of the time it works....

Also helps if you leave the belt on to hold the pulley.

I use an air chisel and a flat punch attachment. Works 100% of the time every time

I would be more worried about the balancer bolt. That thing sucks!!!!!!!!

 

[Krazykid]

well........I guess I forgot to mention that I have already removed the belt and AC compressor. So i am to assume that those mentioning hitting this thing with a wrench and hammer have done so before taking the belt off?

I was trying my luck with the starter bolts tonight, got one loose however the bottom one is being a pain as I can't seem to get enough leverage!?

As for the Balancer bolt........I have a 5' piece of 1" ridgid pipe on stand by for a breaker bar.

Thanks for the help guys, I guess I'm just frustrated from the lack of productive with this project. ( I can't stand not have the right tool for the job.)

I would try the air chissel mentioned above if you have one?? If not put the belt and pulleys back on. As far as the balancer bolt, most suggest pulling the starter and using an extension to hold the flywheel and then using a breaker bar with an extension. I took the radiator and intercooler out and used an impact, it probably takes about the same time but also gives you the oportunity to clean inbetween the radiator and intercooler. Mine were caked with crap......

fwiw, i got mine off with the belt removed.

Im not sure I understand the air chissel method.....I guess I will have to reassemble some parts. I am working on getting the starter out for the insertion of the extension. However the truck having 118K on probably has 1/2ton of crap between the Radiator and intercooler.

The balancer bolt is cake to get off. get a socket and breaker bar. turn so bar is against frame rail. click key. motor does all the grunt work.

You have two options:

1) Use an airhammer on the left (passenger) side of the nut. Just hit it a couple times and the nut should start to move.

2) Get a buddy to tighten the fan belt with a breaker bar on the tensioner. He'll have to really lean on it to hold against you twisting the nut, but it should work.

I have got to be the biggest re-re on this board. what part of the fan nut are you using the airhammer/air chissel on?

 

[custom8726]

The corner of the nut in the direction you are trying to go.....

 

[Krazykid]

Thanks to EVERYONE for thier help. I got the water pump out and taken apart. Here's what I found inside, please advise! Do I need to replace the housing as well?

 

[Dazedandconfused]

I really need to try and do mine soon as well.

Shawn mine looked like that too, it took 125k miles for all that erosion to happen so i did not worry about it and re assembled it back together. one thing you can do is make sure that there is no debris in your coolant.

oh that fan clutch i use 90* long needle nose pliers and stick them in the little holes in the pulley and hold it while break the nut loose.
