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.
