Block heaters are a must in northern regions.
Plug in the block heater while the engine is still warm.
In extreme cold, install two block heaters.
Avoid using ether for cold starts. Use as little ether as possible, about a one second spray into the air intake, while the engine is turning over.
A block heater needs to be mounted as low as possible—at least 2” below the point where the heated fluid will enter the motor or fluid reservoir.
A block heater will provide many years of service with little danger of the element burning out—provided there is good circulation of the coolant at all times.
There is no “pump” inside a block heater. Instead the coolant flows based due to natural convection.
