A leak you still have somewhere will cause the smell of antifreeze can you smell it inside or outside the van.

If you can smell it theres a leak. Pressure test the system and look under pass side door or pass floor, might have a bad heater core. P.S check all your clamps again.

Yeah if you can smell it inside I suspect the heater core it could be just starting to leak slowly. You can rent a coolant pressure tester from auto zone auto part's to pressure test the system.
