LT1 Waterpump replacement

[ConElite]

I dont recall how to do this so Ill post it. My buddy has an LT1 bird and is changingthe waterpump. He removed the screws but he says that the Shaft that connects the Pump to the Cam gear is holding it and will not come loose. From my understanding all you have to do is Pry the pump off.

Is this correct?

Ive done 4 in the past. Once all the mounting bolts are loose just wobble it and it should come right off.

The dex-cool makes a sticky residue that could hold the whole thing onto the block at the coolant ports. I used a block of w00d and a mallet to tap it loose. and the shaft disconnects at either the W/P or the block

not to sound like a doubting thomas but he is sure he has all the bolts out . . . including the one holding the air pump bracket on and the one behind the powersteering pump pully ?

yeah there should be 6 total on just the water pump itself theres one u gotta use an ext and a short socket on thats behind the power steering pulley. its kinda hidden on that side.

Is there any RTV sealant on the shaft by chance?
The *****who I bought my Fbod from screwed up a bunch of things,
Doing the opti, I had a similar problem, all the bolts were out, the thing just wouldnt come apart. turns out there were no paper seals on the inlet/outlets, just red RTV binding the pump to the block(and the drive for the pump, wtf).
It's also possible that the spline drive is worn a little and slipped into a male/male position with the spline interlock if ya know what I mean.
I'm nowhere as experienced as some of the guys on here, but I thought i'd help.
Also, think about upgrading to an electric water pump while its apart IMHO.

Normally it is the dowel pins that hold it on. The coupling shouldn't.

On that note those pins that extend from the block might have corrosion or be warped or something, that would be good enough reason for a lock up. Just put a 2x2 behind the right side against the block and nudge it out.

Hello sir, You would not happen to have a tutorial on how to change the pump. I was on your site and I could not find one. My buddy thats doing this is still having a hard to removing that bracket.

Ahhh the good ol' days of LT1's. Id like to kick the designer in the nuts when he designed that set up.

Should be covered in the cam removal/install "how to's".
