Thanks for the responses. I've just been contemplating if it's worth it to go back to the dealer for $150 without a solid argument.

1.) I'm just looking for the $150 back
2.) The original lower radiator hose is still on the car (it was not replaced)

I spent $230 to fix the problem (including the 1hr dealer labor, indy only charged me $80) instead of the $550 the dealer wanted to charge me to fix whatever they thought was wrong.

Bottom line, the leak is gone and the original lower radiator hose is still on the car. I just have a new temp sensor.
