Car getting real hot....

There are cooling systems and there are cooling systems. About 35 years ago i lost my fan belt returning home from a hunting trip in Northern Ontario.It was late October, cool and raining. We drove all the way home hour after hour and the engine never overheated in my '83 Toyota 4 x 4.When i got home and investigated the water pump was also seized.
...but the rad was constantly wet from the cold rain and air. That was an incredible truck in many other ways too.

The early Model T Fords had no WP or fan. Convection circulated the coolant. Now these were low compression and low power engines with thick iron castings. There also was old one lunger power units that drove a flat belt. These were horizontal engines with a lawn mower style ignition. The top of the cylinder area was open and you had to check the water level and top it up to keep it above the cylinder wall. If it was going to freeze you just turned it over to dump the water out. In the morning you brought warm water heated on the wood stove and started it up.
