The above explanation doesn't make sense to me, but there are plenty of
cars that run hotter under load without a thermostat. Some of them are
probably like the Mercedes, where the thermostat has to block off the
bypass loop. It's also possible that in some cars, removing the
thermostat changes the flow characteristics enough to cause cavitation
in the water pump at high engine speeds. Cooling systems aren't as
simple as they look, and you "improve" upon the factory engineering at
your peril.
