Five Star Fabricating Freeze Plug Diesel Engine Block Heater

The Five Star Fabricating Freeze Plug Diesel Engine Block Heater line gives diesel engines a reliable pre-heat on cold mornings. Also called a frost plug heater or engine block heater, it replaces the freeze (core) plug in the engine block. The heating element sits directly in the coolant and warms the block from the inside. The result is easier cold starts and less strain on the engine.

Key Features:

• Direct coolant heating: The element is submerged in the engine coolant and heats the block.
• Installs in the freeze plug location: It fits directly into the engine block in place of the freeze plug, so no hose modification is needed.
• Cord-connected operation: It plugs into a standard household outlet. A timer can be added so the heater runs only when needed.
• Reduces cold-start wear: A pre-heated engine starts quicker and runs smoother. It also helps warm the cab sooner, helps with defrosting, and cuts wear and tear.
• Fuel savings: A warm engine needs less fuel to get going.
• Backed by a limited warranty: The manufacturer provides a 1-year limited warranty on this line.

Installation requires some mechanical ability, because the coolant must be drained and the old plug removed. Choose the model that matches your engine's freeze plug size, wattage and voltage requirements. A good fit helps keep the seal tight and prevents coolant leaks. Five Star Fabricating (Five Star Manufacturing, sold under the KAT's brand) builds engine heaters for diesel trucks, equipment and other cold-weather applications.
