The bottom rubber cooler hose on mine was also dripping after my TB job, but it turned out that the system really needed to be burped (bubbles came out for a good 5+ seconds) and my new thermostat was also stuck (there was no hot air from vents with heater on highest setting). I think the two problems combined were causing enough of a back pressure that coolant was leaking not through a rip but past the clamp on top, glad that you found the leak before too much of the pink gold was wasted
