KatsHeaters 11603 600 Watt 41mm Frost Plug Engine Block Heater

The KatsHeaters 11603 is a 600-watt frost plug style engine block heater designed to replace the existing frost plug (core plug) in your engine block. This heater submerges directly in the engine coolant to warm engine fluids, preventing them from thickening and freezing in cold weather conditions.

Key Features:

• 600 watts of heating power for effective cold-weather engine warming
• 41mm (approximately 1-5/8 inch) diameter frost plug replacement design
• Operates on standard 120V AC power
• Ensures easier engine start-ups in freezing temperatures
• Reduces engine wear and tear during cold starts
• Provides faster cab heating and defrosting
• Decreases condensation in the engine block, resulting in fewer emissions
• Constructed with corrosion-resistant materials for long-lasting durability

Installation: This heater installs in place of an existing frost plug on your engine block. Installation requires draining the coolant system, removing the appropriate frost plug, inserting the heater with a lubricated O-ring, and securing it with the included fastening system. The power cord routes through the grille for convenient access to an electrical outlet.

Important Notes: Do not use this heater with 100% antifreeze solution. Always unplug the heater before starting your engine. Professional installation is recommended for those unfamiliar with coolant system service.
