Hello, my car's radiator is full of antifreeze and does not overheat. However, my coolant resovoir wont keep fluid. It drains into the radiator until it is all gone. I put water in the resovoir but it drains that and antifreeze. If it is not a leak what could the problem be?

I do have an intake manifold leak on the car. The car does run really high on idle. Could I be leaking coolant into the engine and that being the reason the resovoir is losing fluid? It does take a while to lose the fluid and it only drains while its running.

Its disappearing due to the leak on the intake manifold and being burned in the combustion chamber
