One New Aftermarket Replacement Engine Block Frost Plug Heater - 35mm, 400 Watt - Universal Fit for Tractors and Combines
This 35mm frost plug heater installs directly into the engine block in place of an existing core plug, submerging its heating element in the coolant to prevent freeze-up and maintain engine temperature during cold weather. At 400 watts and 120V AC, it keeps coolant from thickening so engines turn over faster, batteries work less, and wear from cold starts is reduced. Compatible with a wide range of agricultural equipment including tractors and combines.
