What is this hose and where is it supposed to lead?

[slow_c1500]

Hey guys I got a 96 c1500 350 vortec, there’s this hose behind the radiator cap and next to the battery that I was curious about. When I loosen the hose clamp, coolant comes out of it. Is it supposed to look like this? Or is it supposed to lead somewhere and mine is cut for some reason?

My 96 Suburban does not have a hose there

Your truck has an after market replacement radiator in it. That is the heater core return connection for a TBI equiped truck.1988-1995.pre vortec engine.

I think some of the replacement radiators have a hose barb there that are unused in most applicatons. My 95 suburban has heater core return there but is also a 7.4L TBI with auxiliary heat pretty sure my old 99 k1500 didn't have that port, i.e. not needed here.

seems to be the diesel trucks had heater hoses that went to the radiator. could be a radiator out of one of those

My Spectra Premium aftermarket radiator, that is spec’d for my truck, has one of those. Replace that hose with one of these. Just confirm size you need. Well worth it.

Nope. Diesel radiators didn't have caps and the tanks look completely different. The overflow can is pressurized on those trucks, so that reservoir is desirable for an LS swap if using an LS radiator.

Thank you guys for the responses, I’ll see about capping it off with that part Caman96 mentioned.

Also, kinda unrelated but does anyone know the purpose of the big cushion sheet thing on the underside of the hood? Idk whether to call it foam or fabric but mine is pretty worn, is there any reason to replace it rather than just take it off and paint where it used to be?

It is a sound insulation option. Lots of trucks came with out one.

The drain fitting on the bottom of the radiator in my 95 K2500, broke. So I replaced it with the same deminsional size, except original was 2 row, the new one is a 4 row. This past summer no matter how 100 plus days never got over 198. The new radiator had the heater return hose fitting. And had a cap included. The new radiator was originally speced' for 95K2500 with big block, extra cooling capacity.
