Question about Cars & Trucks
Have you checked if the alternator is charging by putting a multimeter on the battery while the van is running it should read somewhere in the vicinity of 14 volts (typically 13.8-14.2). If not reading that or it's higher then that's its saying there's something wrong or voltage regulator on your alternator is faulty or going bad Or could be loose wire or sensor that's giving faulty reading.

Your thermostat may be staying closed, if the top coolant hose becomes hot after the engine running for a while, then thermostat is opening ok. Next check to see if the bottom hose going to the rad is getting warm. If its staying cold then you may have a problem with the water pump not circulating the water around the cooling system. If thats ok check the rad cap is sealing ok. when the engine gets up to normal engine temperture remove the reservoir top filling cap which has a rubber pipe going to the thermostat housing. with the engine running there should be no water coming down the pipe and exiting the filler cap. If there is it could be the rad cap not holding pressure which it would need to be replaced or the head gasket is leaking and pressurising the coolant system.. hope this helps you..
