Check to see if the cooling fan is operational. some time the fuse will blow, rendering this fan useless. if it dosen't blow when the cpu tells it to , the engine will not cool correctly. also, make sure the thermostatisn'tsticking. there are many defective prats in many stores around. the new thermostat you just purchased may be defective.

is the water pump working and circulating the antifreeze. if it is working, I would flush out the system and replace the thermostat before refilling system. you can buy radiator flush at any auto parts store. you can back flush system through radiator. just follow directions on back of flush bottle. have a good one!!
separate problems--coolant should not cause belt to come off. Check all pulleys for wobble/looseness.
For overheating, check for leaks, replace thermostat, flush radiator. If these do not work, possible blown head gasket or cracked head.
u should check for a faulty thermostat first, they are only a few quid and easily replaced. if no change ur most likely faults are a blocked radiator or faulty water pump. u dont sayhow old ur van is but after the thermostat go to the radiator, when its hot check the bottom of the rad to make sure its hot, also brown water means u need to bback flush ur cooling system. even tho u have changed some sensors doesnt mean u got the fan switch sender, dash board sender and fan sender tend to be different sensors, so just double check.
will it sounds like u tryed everything except what could be cousing the problem it is probley the heater core is pluged with hard water or calcium build up or is just pluged and a rad flush wont flush the heater core unless you start the vechial and flushing the rad to do the heaterd core to turn on the heat to high and the fasters fan speed and make shore the van is running.
You say you changed the fan relay and the thermostat? when was the last time you had the cooling system flushed? you could have a blockage in your cooling system that could be keeping the coolant from circulating..
The radiator cooling fan relay has most likely failed. It is underneath the air cleaner on the frame rail just behind the radiator. NO cooling fan = overheating. This is the first thing i would look at. Best way to tell is when the van gets hot see if the cooling fan is on. You will hear it running if it is coming on. It will set a code for the cooling fan relay also.
3)Dirty coolant clogging the pump
A thermostat is the cheapest part to replace, a thermostat opens and closes allowing coolant into the motor as needed to keep it cool, if it gets stuck closed then it doesn't allow any coolant into the motor thus overheating.
A water pump is what pumps your coolant around the system, and if this goes no coolant moves thus overheating. Usually when these go bad they leak coolant and are also noisy when bad.
Lastly could be bad or dirty coolant, a coolant flush can take care of this.
If I were you I would start with the thermostat followed by the coolant flush, both of these can be done in your driveway.
