We did my kid's blazer with the dealer parts.. was about $80 with adapter plate,
hoses, seals, etc....
The "O" rings should be pretty common size/type... you need to take one in to a
parts place... I think my kid found a set at Kragens.. (checker, whatever)
If he still had the truck, I'd do it with better hoses and fittings made up by a
machine shop next time... YMMV

I purchased the o-ring gasket kit from advance auto for 0.99.It came
with 4 small o-rings and (1 large o-ring and a small flat gasket that
goes inside the mount to block.If I didn't have the kit I would not have
known about the flat gasket because the orginal was almost
destroyed.Just thought you would like to know.Bobby
I replaced the gaskets at the block, and took the aluminum lines out.
Cut the swedged portion off, used a 37 degree singleflare tool and went
with AN -8 fittings and stainless braided hoses.
Entire setup cost me just shy of $100-- but I had to buy the 37deg
flare tool <$30> which I needed anyway. So for the price of the
replacement OEM parts <which WILL fail again> I made it more durable,
and next time it fails <much longer time than stock-- I'm going to keep
this truck a while> I can repair it for $15 worth of hose.
Interesting. But, mine has lasted about 15 years and 180,000 miles. I doubt
I'll have it long enough to see it fail a second time.
However, I am going to print out what you did, and stick it my notes, just
The first time I had mine done ($195 labor and parts, ick) they replaced it
with a redesigned model. The hoses are fine, but the gasket to the block is
where it's leaking now.
Leaves a puddle about 5" round every time I park it.
That's where I had to get mine. Around $10 I think. Napa had no idea what
I was talking about.
2 bolts, pull adapter, removed died out o-ring, cleaned recess, installed
new o-ring and remount adapter. No problems since. Drove almost 1000 miles
next day to Indiana.
My inner fender guard fell of a while back so I have a direct view from the
side and the adapter is nowhere to be seen. It is so hidden back in there
I'm not sure how to get to it, let alone get a wrench on it.
Changed the remote hoses a few weeks ago (one was starting to leak) and
yep, I pulled the thru bolt and raised the motor a bit. made it a lot
The newer blazers (93's+) have an additional support rod near the
mount, perfectly situated to get in the way of everything
AND now I see that the adapter O-ring is leaking..DUH!
should have changed it too
I got it done. Had to remove the front drive shaft, remove the bell
housing. Since the tranny lines were in the way, I removed the starter so I
could slide the housing to the side and out of the way.
The o-ring was a flat round rubber gasket. The new one was three times as
thick and round. The paper gasket disintegrated once I touched it. Put it
all back and looks good so far. Took 5 hours.
