'84 6.2 Burb + 91 6.2 motor = water pump issue! Help!?!
 

Bought an '84 Burb that the PO had replaced the original 6.2 Diesel with one out of a '91 (or '92). The '91s serpentine system was gone so he set up a V-belt system on it. Ran it up and down the road; went fine. Long idle; fine.

Sold it to me. Driving it home, (12 miles) the temp pegs!

Am I right in figuring that the water pump is flowing in the wrong direction? I've googled this and it seems to show there may be a problem replacing the '91 water pump with an '84 because of the backing plate and/or timing cover may not be compatible between the two engines? If this is the case, is there such a thing as a reverse flow water pump for these?

OR,,,,,,, am I looking at this all wrong!?!?!? :uhmk:

Did you post the same thread somewhere else? I remember answering this already. I think you still have the water pump for the serpentine set-up. The impellers are reversed because it is reverse rotation.

Hi Spl-K
YUP, wasn't sure I'd get an answer in one....
Stopped in @ NAPA and got the right one today; the PO is installing it tonight to make it right.
Made me feel REAL dumb, lol. I just couldn't understand it until the rotation part of the problem got 'splained'.
Thanks, hope the double post didn't make you dizzy! :m6::m6:

Heck,I don't care. I just wondered if I was losing it or imagining things. I thing the p.o. should be the one who fees dumb. He's the one who thought it would work.
