Cooling System Urgent Question

Glad that this worked out okay in the end!

This incident is a perfect example of how dire things can get when any portion of the plastic connector fails. If it was something that would show symptoms before failure, it wouldn't be that big of a deal. The problem is that it can let go completely without any prior symptoms.

Some argue that all you need to do is plan to replace them every x number of years, treating them as a preventative maintenance item. While I'm sure that would help, sometimes the connector lets go way ahead of 'schedule.' Sucks to have to endure that excitement on the side of the road.

I was more pissed I had to pay for $40 of antifreeze than having to take the ~30 minutes to clamp on a new hose that cost about $10. I just changed my thermostat a couple months back..all that good fluid gone to waste!

The fitting wasn't broke, the quick connect on the hose that connects to the fitting was.

Yes... but with the new metal parts you don't have that plastic quick connect crimped onto the hose any longer.

I had this exact thing happen to me today. Broke in the same place. Nobody had the quick connect so I had to order it. Dorman of course. I'll hunt down an AC delco one later but the wife has surgery Thursday so I got tomorrow to fix. I was at highway speeds and "ding ding ding" the engine overheating light came on. I pulled over immediately and I was about to kill it, the reduced power kicked in. What are the chances that it screwed up a head or something else? 2009 5.3 Tahoe I looked for a complete hose but no luck, only one I could find was for no rear heat. So naturally you have to get a hose and the connector.

if you pulled over right away and shut it off you should be fine, it happens to practically everyone eventually unless you are proactive and replace it early or just get lucky it's a pretty common problem.

It should be fine. Mine did the same thing.

Thanks, this is the last thing I needed right now

I found the factory hose at the dealership today. Instead of the Dorman connection, I will replace with AC Delco. $41 and change.

Welcome to the "I Got ****** by the GM Plastic Tee Fitting" club. I was hauling my boat in a rain storm when mine took a shit and I was in a town and had to go 6 blocks before I found a place I could get off the main drag. One of these broke on me before when I was replacing spark plugs so I kept a spare piece of brass tubing and 2 clamps so if this happened again I could bypass the heater all together to get by until I could get parts to fix it. I always keep extra fluids/tool kit/McGuyver parts in a milk crate in the back of the truck in case shit like this happens. Especially running around with over 300K on the ticker.
