The coolant level in the radiator keeps dropping very low. It seems to be going into the reserve and not coming back when the motor cools. The radiator is new, water pump replaced and several pressure tests have been done. No leaks where detected. Replaced radiator cap and the same thing keeps happening. Any idea what the problem might be?

If no external leaks get a head check done for internal leaks and check trans for coolant as the oil cooler is part of the radiator as well.
