Leaking anti freeze

What are the components behind the TB that could leak anti-freeze?
It is not a small leak, but i can't find what is leaking. I have looked at the heater core and no leak at the lines.

thx

Best way, hook up a pressure tester to Radiator, and test away.

I've read that some cars had coolant lines going through the throttle body, but the only lines I can think of are the heater core lines, but you gotta build up the pressure and watch the leak. Easiest way.

The earlier models tapped off the send/return lines for the heater core and ran coolant through the throttle body. I disconnected mine when I did the HG's almost 2 years ago and have never had a problem even on the cold.

I have removed the wiper motor to try and get a better look, but I can't see the source. Both heatre core hoses are dry.
