If the water entering the engine is very cold
and water circulation at the same time is slow,
the cylinders will run cooler than the heads.
This results in higher cylinder wear, which is
one reason why the reverse cooling was used.
If the water velocity is too low temperature
differences becomes too great between the blocks
and cylinder heads and the water can start to
boil around the exhaust channels of the heads.
We should therefore not expose the engine for
heavier loads while the thermostat is completely
or partially blocking the flow of water in the
engine, to prevent from temperature differences.
