I'm Awesome
The heater core must be leaking on my freshly-acquired '93 C3500 7.4 - the return line is cut and I guess the nipple on the radiator tank is plugged with some unidentifiable object.. but the supply line with a quick-connect style aluminum end is just hanging with no apparent mate. I don't see a pipe plug or anything other than one on the water pump next to the bypass hose to the intake.. so I can't really make out where it used to attach. There's a tab on the hard part of the line that looks like it mounts to a bracket with a single screw, but I can't make out where it used to live. This is a 1993 model 7.4 and doesn't have the plate under the throttle body for the heater hose attachment/adapter like the earlier TBI 7.4's if that helps.
