This engine block heater is manufactured by Five Star Manufacturing Company under their Kat's Heaters brand, known for producing quality cold weather starting aids since 1948. The heater works by warming the engine block and coolant before starting, reducing strain on the engine and improving performance in freezing temperatures. Installation requires coating the heater with silicone grease (sold separately), inserting into the block, and securing with the integrated clip system.
