Thread: Heater hose adapter fitting part #'s and information.....

I spent well over 2 hours on the internet trying to find the part #'s for the metal adapters that slip into the heater hose and go into the alternator bracket.

If you guys don't know what I'm talking about, here's a picture, the pieces that I am referencing are circled in red:

97-98 alternator bracket (with cast metal lower coolant elbow)



99+ alternator bracket (with plastic lower coolant elbow)



These adapters rarely look re-usable when swapping coolant lines. They are usually corroded with dex-crap and just plain nasty. As you can see the 97-98 are slightly different than the 99+ when it comes to the bracket. Pay close attention to which ones you need!!!

Here are the dealer part #'s for replacement adapters (the come with the o-ring already installed on them)

97-98 heater hose adapter - PN # 24506012

99+ heater hose adapter - PN # 24506322

Drive to a JY with a razor knife, pair of pliers and 8mm shallow socket. Look for any GM of the era and you'll have those fittings in minutes.

Remove 8mm holding the piece to the alt bracket
Cut hose
Use pliers to wiggle piece out
