Hello All,
Several years ago, during an engine cooling system flush, the engine was flushed with water, and the water was left overnight for draining the next day. Temperature dropped severely that night, freezing the water in the cooling system...not a happy event, but - - - - happens.
I put a heater under the tractor and unthawed the engine. Several obvious areas were damaged by the freeze.
1. The metal connector (termed thermostat housing) from the top of engine to the hose going to top of radiator broke.
2. The cooling system "bottom tank" cast housing cracked (welding shop repaired the cracked area).
3. I have not pressure tested the radiator, but that can be replaced easily enough if bad.
These were the only visual areas of damage.
The engine turns over without any problem.
My main concern is the engine block. [b:83bd6c5f88]There were no obvious signs of coolant in the oil,[/b:83bd6c5f88] however examining the block for cracks will be labor intensive and expensive (disassembly and dye testing, etc.). Based on any information or feedback that you have, can the Cub engine block take a hard freeze, without damage? I know any reply will be highly speculative, but I am trying to avoid disassembling the engine, and maybe take a chance it is OK.
If you have any personal words of wisdom, it will be appreciated.
