Anybody know how to remove these heater hose fittings? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm mostly interested in the white quick connect, which no longer has a nipple on it and which has my quick connect removal tool stuck behind it -

It's an 04 2500HD with a Duramax; I could get the fitting to move forward but it didn't come off.

My neighbors blew out when he was heading fishing one day.
I seen the trail on the highway.
He came back a few minutes later

Luckily he was close to home.

Here is a video that I hope will help

Thank you; basically I'm doing what he recommended for the Silverado. I guess I'll keep trying, only harder.

I am glad it happened a couple miles from home and not on a trip to Atlanta or somewhere.

It might be worth making a fork to pry against the fitting.

I was hoping you might have some input.

I found an old Cub Lowboy shift fork in my junk metal pile; I'm going to try hooking the slide hammer to that and give it a whirl.

Thanks -

Keith you probably have already thought about it but slide hammering on that fitting may pop a leak on the heater core. I worked and worked to get mine to release using the tool that eventually worked.
What you might try is a dremel tool or similar to split that coupler lengthwise then peel it off the tube.

These come in handy at the strangest times.
You don't run as high a risk of cutting through the metal tube inside as you do with power tools.

Thanks guys; I got it.

I was able to get my quick connect tool unstuck and I was moving the fitting around in order to "reset" and start over, and it came right off.

I think the stuck tool was preventing the fitting from slipping off.

I have replaced those replacement fittings twice on my Yukon. They all seam to leak just a little. So I bite the bullet and bought GM ones.

That's what I used, came off in seconds. I cut it just enough to use a screwdriver in the cut slot to break the plastic.
