Trick to removing radiator hoses?

fs34 · 12-22-2020, 08:32 PM

I’m trying to remove the upper radiator hose and I can’t seem to get that sucker off. I’m afraid I will break the plastic connection at the top of the radiator.

Any tips/recs?

Thanks in advance!

Had the same issue when I swapped to a do88. I suppose I could have cut the hose off with a box cutter since I used a new one with the new radiator so that's an idea. My oem radiator is stored with the hose still attached as a result.

Curious to hear other ideas.

i've used a 90* pick to pull between the hose and receiver on the cooler in the past. it kinda breaks up the seal a little bit.

I sprayed armor all on mine and let it soak in. Then just pull the pins off completely and pull while wiggling. There are no pressure tabs! Water deposits will fill in any gaps and cracks making the fit extremely tight. Wiggle and pull is all ya have to do. Maybe wrap a towel around it to get a good grip without trashing your hands. Do not use tools like channel locks. A warm engine helps too.

This and a soft twist will get it free. Be patient and it will come off slowly.

Must use a pick like roastbeef said.

Is the pick used to pull? Or to squeeze in between the hose and connector?

Used to stick between the hose and radiator to break the seal and any gunk that's built up over time.

If it's really bad you can use a heat gun to really heat it up, carefully of course don't burn it. Get it as hot as it would get on a hot day with engine running.

Or drop lots of boiling water on it.

Otherwise you mostly wiggle it out patiently. It eventually brakes loose.

I think I sprayed silicone lube with a straw into the junction. I was doing a water pump / thermostat job and the fan was out. That helped. It is super easy to pull that fan out but you have to be careful because the housing is brittle - and the replacement is $900. I didn't break it, btw.

You'll see people on youtube tell you to use a prybar. I passed on that idea.
