Help with heater coolant line

[rdezs]

As a general rule, stick with OEM... particularly on fuel pump, lifters, fuel injectors, all sensors and switches. Exceptions to the rule are Melling oil pumps and Felpro make some excellent oil pan gaskets as well as front and rear main seals. (Head gaskets as well) That y-pipe in the heater hose down near the water pump, either stick with ACDelco because the plastic is different than the aftermarket, or buy an aftermarket section of hose with the y pipe and replace the y-pipe with a metal one from Dorman available on Amazon. Comes with new spring clips as well.

The heater hose
that "Y's" out down by the thermostat housing has a
good replacement for it as well. it has a metal Y instead of the factory
plastic one... Another failure point on our "oldish" vehicles.
I like gates stuff. But OE is fine and other brands too. Just use what's
convenient for you. One very borrowed time for all the rubber/plastics
at 12 years old and 200K

What you do moving forward depends on your plans for the vehicle and budget. I'm assuming it still has the AFM/DOD active? Where it switches to 4 cylinder mode at light cruise? If you want to keep it for another hundred thousand plus, make plans to delete that. Many write-ups on the forum detailing it.

The last owner replaced all of the lifters with GM AFM lifters at 190k. So currently I’m not sure if I’m going to delete AFM in the near future as I’m assuming the current lifters will get me at least another 50-100k. I bought it cheap and it was neglected so I’m trying to make it last at least to 250-275k

So I was laying on top of my engine fixing the dreaded exhaust manifold bolt issues and my elbow slipped only to get caught by a heater hose and I broke the connector. Pretty upset but it happens

What’s the best fix for this? Is it to buy a new coolant hose or is there something else?

THESE ARE THE CORRECT PARTS THAT YOU NEED, 1 OF EACH. BEST TO USE OEM FOR THESE

Thank you. I already ordered everything and am using OEM hose but went with Dorman connector, maybe not the best idea but it was half the price as the OEM is now $30+

I found each of the T's went up $5 on amazon, since I last bought them in 2019 the black one now $24 and the white one now $29

Change out ALL of your cooling hoses, before you get stranded somewhere. They deteriorate over time with the heat of the coolant and the heat of the engine bay. I believe that the manufacture date is stamped on the hoses, and if they are original, replace them now.

You don't want this to happen out on the road, like it happened to me.

And by all hoses, let's not forget the two that nobody thinks about till they're on the side of the road. The two hoses they're exposed to road spray and exhaust heat constantly. The ones behind the right rear tire that go up to the rear heater core. While they're only available as a complete line set with the metal tubing to the engine bay, they're easily modified from above the spare tire with a half inch compression fitting to a half inch hose barb.... And Dorman sells the 90° 3/4-in quick disconnect to half inch hose barb. That way you can just use any heater hose and makes for a easy repair.






I'm amazed how many people don't even know those hoses are back there till they see coolant dripping behind that tirethe Usually on the side of the road in the middle of a long road trip!
