Heater hose replacement

[EWC]

Yes , reuse the tube . The green heater hose might be of a different heat range . You'll see what I mean about cutting the clamp off . It doesn't take much , after all it's just aluminum .

Somewhere along the line, I am almost positive that hose was mentioned which NAPA was supposed to carry which has a coil molded inside the hose. I'm unable to find the link at the moment. I stopped at one of our local stores today and they said they had no such item. They did, however, show me some 5/8" formed hoses that I could connect to if I needed a custom route. That could be handy in the future.

Get some more light out there and I’ll try to get some better pics of how I routed my hoses. I thought sure they would kink in the bends but they did snot. OOOPSSSssss, meant not.

 

[MrMarty51]

Okay. I took several pics of the heater hose routing, how I did it on My truck.

Thanks. That's helpful. It's good to see that a regular hose will work without issue. I was considering keeping the aluminum for a portion due to routing, but this doesn't look bad either.

I personally run the OEM style. if yours it messed up from someone messing with it, both the 92-95 and 96+ part numbers are still available, genuine GM through rock auto for like $75.

call me paranoid, but i like the way the factory hose routes near that downpipe, not sitting against or rubbing on anything.
fresh orficed quick connect and im good for 20 years. not a perfect system, but I dont think its as bad as made out to be.

Heater core outlet for green hose is 3/4". Aluminum tube is 5/8". Is there a reason for the restricted area in the aluminum tube?

All I am seeing is bulk hose that can be cut to length. Must be missing it?

part # 15986676 @ R.A.

The bend in the bulk hose in the pics is not as close to the down pipe as it seems in the photo.
It is a safe distance away or else I would have done something different.
Copper tube can have some real clean sweeping bends in it too without causing a lot of restriction.
An old school bus I once owned had copper tube plumbing.
I did make a mistake once and touched the back of my hand to some, it was an instant and immediate water blister to the affected area.
I do sometime go to the NAPA store where they have quite a selection of black plastic fittings, elbows, Ts, etc.
They do have them in the heater hose sizes. I have used the 90* elbows and made a lot of different configurations of whatever I was needing.
These fittings do withstand the high coolant temps and I have yet have had one fail.

Thanks for the part number. Not sure why I couldn't find it. Hard to believe that is still available.
