Hi and welcome to FixYa!
Few things to look at to resolve the overheating problem. Here are the following:
- Radiator is clogged
- Radiator fan blower is weak
- Water pump is worn out which may result failure on coolant cycle
- Cracked cylinder head
These must be replaced if found out faulty or damaged. Hope this helps and thank you for using FixYa! Have a good one!
Has any one had problem with running hot and over heating with a dual core for rear...I have bad control panel now on order blower stuck on ven and just blows cold air...rad, stat, pump, hoses all new ..hoses going to front heater core both under presure and hot..not a head gasket, no leaks..feedback needed hate to do all the work of replaceing heater cores to still have same issue seem more or poor circulation maybe caused by rear dual core and bad control panel...Please help if you had any issues with dual system..Like to know how do you test the dual beast!!!!!

JUST WONDERING IF YOU FIGURED OUT ISSUE I have dual heater cores and dual rear ac..I think my over heating is has something to do with rear cooling system not rotating coolant...Just wondering what fixed your van.. did all the basics like pump hoses, sensors ect...It down to rear heater core or defect heat panel to working only in one mode....Will be pluging all ( 2) heater core hose directly to each other to see if improves coolant flow and ordered new panel from ebay..but hard to find or even see darn heater hoses on dual system !!!!
Note: if you losing your coolant yet you see no leaks it a head gasket..Stat could be prob.. can test it byy just running with out it.....water pump could be worn but maybe you have same issue I am having I believe my issue is electrical maybe some fun I cant find or panel just bad..let me know how you fixed your van..Car
Do a compression test could be that your head gasket is leaking and pressurising the coolant system
