Trying to figure out the name of a part

Good afternoon,

Is coolant leaking from there or is coolant dripping on this?

It looks like a wire harness from your picture. Where does either end go?

One line looks to go to the heater core, the other I can't seem to pinpoint. The part is rubber and has a plastic tube in the center. I thought I could just replace with a rubber hose, but was concerned the plastic piece inside was needed. The coolant is from the line that goes into the part. The line slid out so I put back in a put clamps on each end. Photo shows tape as a quick fix.

Got it.

From your description, it sounds like a heater hose. as long as there is no electric involved, you can just replace the hose.the other end should go to the intake manifold.

What motor? I will try to get a picture for you.

Roy

Thank you. The motor is a 5.4 Triton. The lines are very small. I will probably replace with a small hose since there is no electric.

Yes, try that and let me know how you make out?

Roy

In doing more research I figured out that the plastic piece is a vacuum connector. Since it's a vacuum connector, would it be safe to go ahead and replace the whole thing with a vacuum hose?

Thank you.

You cannot have a vacuum fitting in a coolant line. that makes no sense.
