So when we are sitting in park with the engine running the van overheats. As soon as we start driving it cools down. The radiator is not cracked. The engine coolant will be boiling in The overflow jug

make sure your fan is working properly, if the radiator fan is not functioning appropriately it will cause that issue, when the van is running the radiator is getting vented therfore it cools properly but if the fan is not working or malfunctioning it would cause the overheat when not running/ getting vented. Hope this could help solve your issue.

If fans are working your radiator or A.C condenser coil if it is in front of your radiator could be partially clogged with dirt and bugs restricting air flow to radiator. Clean radiator and A.C coil with garden hose and nozzle or better yet a pressure washer. After cleaning should have better air flow across the radiator and A.C coil.
