Oops, you better check those part numbers, because they are not for an LT1.


o-rings are GM PART # 12553792 (need two)

GM PART # 9423592 long bolt (need 4) 3/8-16 x 4

GM PART # 9440073 short bolt (need 2) 3/8-16 x 2

 

i looked it up on bing, lol sorry if it is wrong

 

Just go to a parts house and look at their assortment of o-rings in the tackle box. Find a pair of o-rings that allows the coupler to slip snug over but can still be easily removed. IMO, these o-rings are for vibration dampening and not really sealing of fluids. They will cost less than a dollar.

GM would likely want $10 for the original parts.

 

$1.30 list price for the GM o-ring.

 

ok thanks now i have to look for the water pump bolts having trouble finding any of them

 

my question is the two orings one goes on the driveshasft right? and the other on the back of the water pump?

 

What's wrong with the original bolts? I've had my w/p off and on a couple of times, over the years, for various maintenance "projects", and always used the OE bolts (with a dab of teflon thread sealer, of course)

 

bs 17 dollars a piece for the water pump bolts. Wth ima go to autozone or use the same ones that are in the water pump.
Do you think if I use the same water pump bolts it will be ok?

 

i guess your right. the same one should be fine. im just paranoid cause one of the guys botls in a youtube video snapped while trying to remove them.


my question is the two orings one goes on the driveshasft right? and the other on the back of the water pump?

 

If you want to, you can put one of the o-rings on the back of the water pump drive "stub", and the other on the drive "stub" that passes through the front cover of the engine.

If somebody snapped a 3/8" bolt by removing it, either it was way too tight, or the guy was a klutz. IIRC, the torque spec for those bolts is 33 ft/lbs.

 

Yes and clean and grease the inside of the coupler.

 

by any chance what kind of thread do i put on the water pump bolts when i put them back so they wont leak?

 

Thread sealant? Permatex high temp. Comes in a little tube you can get at most any auto parts place.

 

You only need sealant on the bottom two bolts. Just FYI...

 

I need to change my intake gasket. any little parts or gaskets I should consider changing at the same time? i saw a list of parts, but i'm wondering what I should consider.

 

thanks you guys for helping out
