This direct-immersion heater warms the engine coolant from within, providing efficient cold-weather protection and improved starting performance.

Key Features:

• 400-watt heating element provides effective engine warming in cold climates
• Fits standard 28mm (1-1/8 inch) frost plug openings
• Direct immersion design heats coolant efficiently for faster warmth distribution
• Thermostatically controlled to prevent overheating and reduce energy consumption
• Heavy-duty construction with corrosion-resistant materials for long service life
• Includes grounded power cord for safe outdoor use

Benefits:

• Enables quick, reliable cold-weather starts by pre-warming the engine
• Reduces engine wear during startup by ensuring proper oil flow and viscosity
• Improves fuel economy by allowing the engine to reach operating temperature faster
• Decreases harmful emissions by promoting complete fuel vaporization
• Extends engine life by minimizing cold-start stress on internal components
• Provides cabin heat more quickly for improved driver comfort

This frost plug heater installs directly into the engine block by replacing an existing frost plug, providing a permanent cold-weather solution. The thermostat automatically regulates temperature to maintain optimal warmth without wasting electricity. Ideal for diesel and gasoline engines in cars, trucks, SUVs, and fleet vehicles operated in cold climates.
