My van keeps running hot. I have changed the thermostat, water pump and radiator. Whats causing it to run hot?
There maybe a blockage in the cooling system that runs through the engine. Try flushing cooling system with a good Super cooling system flush it will circulate through the engine block and clean entire cooling system. No promises but its worth a try.
Have you checked to see if radiator fan is working?
you can have an air bubble in the system aka vapor lock...
