First of all you have a coolant leak, track it down because after you fix the van you don't want this to happen again. (Be sure to check the heater hoses) Have the cooling system pressure tested in order to locate the leak.
The cylinder heads are probably warped on your van. (Caused by overheating) Have a shop do a cylinder leakage test to verify this. This test injects compressed air into the cylinder with the piston on TDC. The
place(s) where the air esapes identifies where the problem is located and gives very good insight as to the problem.
