Blocking off rear heater

[blondie70]

Howdy. Wanting to block off/isolate the rear heater core as I do not use it. This to avoid future failure, etc..
Any of you guys know a practical way to do this ?
Thank you
Pete

Well, you can simply remove the Y adapters near the firewall and install regular adapters like what the trucks have.

There's a special split ring removal tool to remove those quick connect adapters.

Pics, please? Might also be of help if someone needs to do this temporarily.

Here's my 1999 Silverado. When I had just bought it in like 2008 one of those plastic quick connects broke. I just removed the hoses and connected them directly into the aluminum tube with hose clamps. Back then I didn't even know they sold quick connect replacements.

What I actually did first was removed the hoses and bought a brass coupling from the hardware store (I think it's 1/2" or 5/8") just to get the truck running again. It was in the summer and I was in college and no tools. When I went home to my Parents' I just broke off the plastic and hooked them up directly as shown. I think I still have the coupling in my glovebox.

^^^This. You'll get new connectors and "delete" the rear heater in one shot. Use OEM connectors! Flush and blow out the rear heater pipes and core and cap off the lines in case you or a future owner wants to reimplement it.

I have the connectors and split ring tool ordered....it is gonna be a pain to get to. Will have to rig up something to lay on. Kinda under a ridge too.
Thanks for all the tips on this

Why the split ring tool, whatever that is? Just cut 'em off with dykes.

Do you have more information on the tool needed to remove the heater hose connectors?

 

[blondie70]

When I was ordering some connectors to bypass the tee....a split ring plastic tool was listed among the connectors. I ordered it....hope it is the rite one and works !!! Think it was the Gruven site.

Cardboard's good to lie on. Be prepared for coolant in the face.

Be prepared for coolant in the face.

Invest in one of these to help keep that to a minimum. You can disconnect the tee at the firewall and run one of the tubes down as far as it will go and suck it dry. I use it for all my fluid extractions. I was able to replace a radiator without a drain pan. Just removed coolant as I took things apart from top to bottom.

Also good for draining the transmission pan to do a filter change without a bath.
