Heater Hose at firewall leaking out of band crimp area

[Happy Hummer]

I was under H3 today working on the front and rear drive shafts ( wanted to correct my out of phase goof up on the front)(and wanted to just verify the rear prop shaft) was still good since rebuild.
I'm down there and notice antifreeze leaking and dripping on me (add explicative):giggle::emb::mock:
I decided to finish up with what I was doing check the lug nuts again. When I was wrapping up I found that the heater core hose nearest the engine at the fire wall is leaking from the banded crimp.

What a pisser...


By the way the credit for this pic goes to someone else. Not mine just an example pulled off web...

I believe there is and Reloader likely has one in his toolset.

Ended up cutting the banded crimp off and purchasing new stuff.
Head to O'Reilly auto parts and pick up ... Gates 82500 & 82502 + some appropriate hose clamps.
I reused the plastic locking insert as the one with Gates brand sucked (my opinion).
Just used a angle grinder, pneumatic die grinder, associated supplies and patience. I think that it worked okay. Just scuffed the outer diameter of the hose while doing it but not terrible.
Wanted to follow up.

Oh and be careful putting zip ties around these hose to silence the vibration because I believe it stressed the crimp to begin with. Of course the vibration does way more to stress me haha.

That's probably what I would have done too. You might double-check your engine mounts too and your radiator pressure. When ya see things like that, sometimes they're symptoms of a bigger (hidden) problem. Put the engine in D and give is some throttle (foot on brake). Watch for any engine movement (with hood open). D the same in Reverse.

Smell inside your radiator for combustable gases ...and check the top of the cap for milkiness. Check radiator hose for higher than normal pressure (like a failing headgasket). Might just be a fluke on the heater hose, but a failing head gasket can go months or years w/o blowing entirely but usually give a few hidden hints that something is up. Doesn't take much to check and rule out. Just a suggestion.
