Risking a clarification here, while I appreciate ORR's brevity and wit.

If your van is running hot, the cooling system is not keeping up with
demand and something needs attention.  If your cooling system is operating
properly, you could be running apple juice or skim milk in it and the
running temperature will be determined by which thermostat is installed.
Exotic fluids do not change the setting of a thermostat.
