I have one "quick" disconnect fitting that is keeping me from pulling the rad on my Heep...
I have tried the QD tool set that I already had, a Lisle brand one with the plastic tools... bought a similar looking set from Harbor Freight... bought a 3/8" "Powerbuilt" QD tool from Carquest... NONE OF THEM WORK! The problem appears to be that the line is 3/8" but none of the 3/8" tools have a large enough outside diameter to disengage the clips. (there are four fingers inside the female fitting... I can see a different but identical fitting, if that were the one I needed to get off I'd just finesse it with a small screwdriver, but the one that I really need to get off I have no clearance around it, the QD is right up against the radiator and the driver's side frame rail.) I tried shaving a little off the plastic of the Harbor Freight 1/2" tool to see if that would work but it is too flimsy to disengage the clips. I also tried wrapping the Powerbuilt tool with metal foil duct tape to increase its OD, but the fingers just peel the tape off.
If anyone has a tool that is known to work on these connectors, a mfgr. and model no. (and where you purchased it) would be greatly appreciated. Otherwise I'll just hacksaw the crimp off the line and use a hose clamp, ugly though that may be... I really want to avoid doing that though.
thanks
