I have a 2006 Cadillac CTS and the transmission coolant line is leaking at the lower left side of the radiator. A new hose is $150, but what about the terminal on the radiator itself? Do I replace that as well? Or is there a clean up way to make it stop leaking? I saw one person eliminate the special connection altogether and clamp it to an aftermarket terminal that has a hose attachment nipple. What say you?
