Question about Jeep Grand Cherokee
How do you disconnect the heater core metal hoses from the heater core in a 1999 jeep cheroke classic?
Hi I'm Peter, Curious as to why you said metal hoses as most heater cores have metal pipe inlet and outlets that protrude out of the firewall and then the rubber heater hoses are connected to them. I may have to go look that one up but my question is are you taking the heater core out, and if so have you already take the dash area out to access the heater core? Let me know and I'll see what I can do to help but right now I am wondering if you might be talking about the transmission coolers metal lines. Sorry I'll wait on your response.

I suggest review the ZJSecc24-Heating-and-Air-Conditioning
First you'll need remove the heater A/C unit from the vehicle; after, remove the heater core retaining screws, and finally, pull the heatrer core straight out of the housing.
Hop helped with this (remember rated this help) Good luck.

Sure, just cut pressure back if you have a lot of pressure in that hose, as your system usually runs 15-20 psi. You'll be ok, as long as one side is open. Make sure you reverse flush as well, it helps dislodge debris. If you plug lower tube, attach a hose to other, and use a funnel on that hose, or hold it up high, and pour CLR into core, and let it sit in there for a while, it will help loosen up calcium etc, that builds up inside core, before you flush it out. Just a suggestion, but I've done it on several to increase flow through core when idling to increase temperature in vehicle at idle.
