how do i find this leak? its a 1.8t. i have coolant temperature sensor out right now. i can't see a bad hose from above or below.seals seem ok on sensor.coolant is clean. so is oil. never overheated before it bursted somewhere while driving. the red cooling system warning light started flashing. upon reaching home, there was a hissing sound of hot air release while coolant gushed down off of transmission to the ground. it was too hot to deal with. i don't want to put CTS back in yet but may have to, to find it. its a tight fit

That looks like a home-made plug for the combi valve port.
