I bought this truck broken and I don't know any of its history other than it has a blown head gasket.

I've tried to be diligent about labeling things and it's possible I labeled this but the tape fell off. It seems a little rough on the end and I'm a little worried it got snapped off? But I imagine if someone snapped it it would be more jagged.

Either way I don't think I removed the hose that goes to it and I'm not sure where that hose would go.

  • Have you accounted for heater hoses? If there is a similar-sized hose nearby on the firewall it could be a heater hose. Jul 8 '16 at 4:18
  • The heater core would be to the left of pictured above and the 2 hoses would be on the top. The inlet one would the one with the little device attached to it.

I see what appears to be a A/C evaporator coil assembly housing based on the large aluminum tube at the top and a smaller one at the bottom. I would say that is the drain hole for the condensation to drain out. No hose required.

  • That's a huge relief. I'll mark it as the answer but won't know for sure until I get it all back together. Thanks man.
