Description
When cold mornings turn your reliable tractor into a cranking, stubborn machine that just won’t fire up, you’re likely dealing with a cooling system that can’t keep the engine warm enough for easy starting. This 400-watt freeze plug block heater replaces a standard freeze plug in your engine block and keeps the coolant warm overnight, so your diesel starts quickly even when the thermometer drops below zero.
What You’re Getting
- Powerful 400-watt heating element provides plenty of warmth for reliable cold-weather starts
- 35mm diameter fits directly into standard freeze plug opening—no modifications needed
- Quality construction handles the thermal cycling that comes with heating and cooling over many seasons
- Complete with replacement cord GE24C for easy electrical connection
- Direct replacement design installs in place of existing freeze plug
Built for Real Farm Work
This block heater fits a range of compact and utility tractors including LS G3033, G3038, R4010, R4020, R4041, R4047, U5020, and U5030 models, New Holland Boomer 40 tractors, and Caterpillar 301.5 excavators. These machines typically handle everything from loader work and hay production to landscaping and construction tasks where reliable starting matters most.
Made to Last
Farm equipment operates in tough conditions, and this block heater is built to handle years of thermal stress. The heating element maintains consistent temperature output while standing up to the expansion and contraction that happens when engines heat up and cool down repeatedly throughout the seasons.
Installation Notes
Installation involves draining coolant and removing one freeze plug from the engine block—typically a job for someone comfortable with basic engine work. Make sure the engine is completely cool before starting, and use proper coolant disposal practices. The 400-watt draw means you’ll want to plug it in 2-4 hours before starting in really cold weather.
