Heater core'd be leakin' on the floorboards, not in the engine compartment!!!

Will be dragging it home tomorrow for a better look.

Woohoo! Easy fix!  The heater core fitting broke on the engine side of the firewall. A piece of 1/2" copper tubing from the back of the truck and a couple of hose clamps will do the trick, at least for now since heat is actually nice sometimes....

That white plastic fitting has sure gotten soft. The other side is black plastic, seems odd they would be different. I'm thinking of just replacing both.

Hey, I think someone mentioned that a few posts up.

If I had to do it again, I’d replace the hose. There is a knob on the end of the copper tube you have to cut off to get a hose to slide on if you use my fix. I was out in the woods when I did mine and didn’t have any option.

Good deal those type of easy fixes are always nice it makes up for the other type

Dorman products part #800-409 or 800-916 should fix you up, any parts house should have those in stock

Thanks.  Is it odd that they are different?  As far as I can remember, I've never had any work done on them.  Also have to find the tool to release them I think.

Nope,. if i remember the tubes are 2 different sizes, got to love better engineering with plastic

Just watched a video of exactly what I need, the white plastic one failed on that truck as well. I guess I need a 3/4" quick disconnect tool, I wonder if any of the auto parts stores will loan those out?

The tool is cheap. I think around 5.00. I bought one expecting my other hose to break at some point, but never has. My white connector is the one that broke too.

Seems like that is the one made out of the inferior plastic as all of the videos show it as the one being replaced.  Does that little tool push into the fitting or does it just compress the ring in the back?  I've got a tool to remove sharkbite plumbing fittings that I am going to try tomorrow. 

The one parts store in town that I talked to only has them as a set for about $10, still cheaper than having someone else do it. And, then I'll have the tool when the other two or three similar rigs blow their fittings and I can charge to fix it.

Don't think the one for shark bites will work. Believe it has to actually slide into the fitting.

That is the case, now I have a set of them....  ;-)
