What’s this part called (freightliner cascading 125)

Bracket

 

That’s a HoozyWhatsIt.

 

That’s a leaks-a-lot coolant line.

 

A whatchamajigger.

 

Might be a supply line for a/c in bunk , never seen one that goes into a frame though. Most likely a thingamigger .

 

Stupid question - do you have an autotrans in the truck? If so then it could be oil coolent lines for the trans.

 

Are you asking about the bracket or the line/tubing?

 

That looks like one of the transmission lines that connect to the radiator. I think that bracket is to reduce tension on the fitting.

 

No no no all y'all are wrong. It's a thingamajig.
