25. Cold Weather Starting Aids
Warning: Starting fluid is highly explosive and toxic. Handle starting fluid spray cans with
extreme caution to prevent fire, explosion, and personal injury.
Caution: Do not use excessive amounts of starting fluid when starting the engine. Using too
much starting fluid will cause engine damage.
Diesel engine starting fluid is used to spray a highly volatile fluid into the air cleaner intake of the engine.
The starting fluid helps to ignite the fuel at low ambient temperatures. When the temperature range is +32°F to
-25°F use starting fluid (fig. 36).
