Description
When winter turns your trusty tractor into a cranking, stubborn machine that just won’t start, you’re usually looking at a bad freeze plug heater or no heater at all. Nothing’s more frustrating than burning daylight trying to get equipment running when there’s work to do. This 400-watt freeze plug heater replaces your existing freeze plug and pre-warms your engine block, so your diesel fires up reliably even when it’s below freezing outside.
What You’re Getting
- Powerful 400-watt heating element that gets your coolant circulating and engine block warm
- 40mm size fits perfectly in place of your original freeze plug—no modifications needed
- Reliable pre-heating reduces cranking time and saves wear on your starter and battery
- Built tough to handle repeated heating cycles through years of cold-weather starts
- Standard electrical connection works with existing wiring or extension cord setup
Built for Real Farm Work
This heater is designed for compact and utility tractors that handle everything from feeding livestock to snow removal. Whether you’re running an LS compact for daily chores or using a New Holland Boomer for loader work, this heater ensures reliable starts when temperatures drop. It also fits ASV skid loaders and Caterpillar excavators, making it handy for construction and material handling equipment.
Made to Last
Engine block heaters take a beating from constant temperature cycling and exposure to coolant and weather. This one’s built with a durable heating element and corrosion-resistant housing that stands up to years of winter use. The robust construction maintains proper heating performance through thousands of start cycles without burning out or leaking.
Installation Notes
Installation involves draining some coolant and removing the existing freeze plug from your engine block. The new heater plugs right into the same opening with a snug fit. Make sure to use appropriate thread sealant to prevent leaks, and don’t forget to top off your coolant when you’re done. Most folks find it helpful to plug the heater in for 2-3 hours before starting in really cold weather.
