If the engine will clear the floor of your van slowly roll the hoist back away from your van and out the door. Congrats! You have just successfully pulled the engine.
You may want to continue to drain the oil and other fluids into a container to prepare it for transport. Don't leave it hanging around too long in case something breaks.
If the engine will be discarded, drop it to the ground on an old tire or engine rack and pull off any good parts you may need later or may want to trade with other van owners.
