KatsHeaters 11813 Freeze Plug Engine Heater Cartridge

The Kat's 11813 is a freeze plug engine heater cartridge designed to provide reliable cold-weather engine warming for easier starting and reduced engine wear in freezing temperatures. This direct-fit heating element replaces an existing freeze plug (expansion plug) in the engine block to deliver heat directly to the engine coolant.

Key Features:

• Installs in place of existing freeze plug for direct coolant heating
• Provides faster, more efficient engine warming than external heaters
• Reduces cold-start engine wear and improves oil circulation
• Helps improve fuel economy during cold weather starts
• Durable heating element designed for long-term reliability
• Standard 120V AC operation with grounded plug

Freeze plug heaters are ideal for diesel and gasoline engines in cold climates, delivering warmth directly to the engine coolant system. This helps ensure your engine starts quickly even in sub-zero temperatures while extending engine life by reducing cold-start stress.
