Default How to disconnect coolant hose

How do you remove this rubber hose from the hard pipe? I pulled the clip and it looks like a quick disconnect but it doesn't seem to pull out.

Not sure why I'm having a hard time getting this posted. This is the coolant hose connecting to the hard pipe going up front.

Hi, I’ve not personally pulled that hose (which one is it, anyway?) but when I did a coolant drain, I had to slip a small screwdriver between the hard pipe and the rubber pipe and move it around the pipe to “break the seal.” Probably not the best idea due to potential scratching of the hard pipe, but it worked for me. Good luck.

This is the large coolant hose just below the coolant reservoir. The hard pipe goes to the radiator. you shouldn't have had to disconnect this section to drain your coolant.

Looks like just wiggle it and pull straight out. Perhaps gently pry on the metal flange.

The photos here should help you see how it's constructed.
You are just fighting with the o-ring.

It's just the rubber o-rings stuck. Spray some penetrate into the crevice and insert a screwdriver in between the metal housing and the metal "ring" of the rubber hose end. The rubber hose has a metal (steel)end made on the end with a large o-ring sealing to the inside of the aluminum housing.

Hi. Daniel. Why are you showing this? For those wanting to flush the coolant from their cars? Draining associated with swapping out a coolant expansion tank?

Spray the flange with WD40. Insert a flat head screw driver into the tiny gap between the flange and the metal pipe, and pry. Wiggle, and wiggle, and be prepared to get really wet.

Thanks for the replies. I just didn't want to force it if I was missing something.

Nuttyprof, I'm just replacing the hose as preventative maintenance.

Anyone happen to have the part number for that hose. The code is worn off on the hose and I'm having trouble finding which one it is on the various parts diagrams.

To clarify this hose goes from the t-stat to the hard pipe (I guess return line?).
