The Van would not blow out any heat - only cold air today then overheated. Top radiator hose felt hot, lower radiator hose and cap felt cold.

Put in new thermostat - no change.

Need help please. What should I do next?

Unsure

With the engine you have the likelyhood of a blown head gasket is very high. You should have some chemical testing done.

Should have added - There are no visible leaks and no trace of that coolant odor...

That doesn't change anything. A cooling system pressure test should be done also.
