Description
When it’s fifteen below and you’re trying to get chores done but your compact tractor just won’t fire up, you know how important those little heater plugs really are. A burned-out heater plug means your diesel engine can’t get the heat it needs to ignite fuel properly in cold weather, leaving you cranking away while burning daylight and wearing out your starter.
What You’re Getting
- Direct replacement heater plug that provides reliable cold-weather starting assistance
- Proper electrical specifications designed to heat intake air for optimal diesel combustion
- Quality construction that handles repeated heating cycles season after season
- Corrosion-resistant design built for harsh farm environments
Built for Real Farm Work
This heater plug fits compact tractors from Case IH BD series and New Holland’s compact series that handle everything from loader work around the farmyard to mowing and general utility tasks. When you’re running smaller diesel tractors that need to start reliably regardless of weather, working heater plugs make all the difference between getting the job done and calling for help.
Made to Last
Farm equipment sits outside in all kinds of weather, and heater plugs take the brunt of temperature swings and thermal cycling. This replacement is built to OEM specifications with materials that withstand the repeated heating and cooling cycles while maintaining proper electrical performance for thousands of start cycles.
Installation Notes
Make sure the engine is cool before starting, and clean the threaded port thoroughly to remove any carbon buildup. Don’t overtighten during installation, as this can damage the plug or cylinder head threads. Test the heater plug operation by checking your dashboard indicator light before attempting to start in cold conditions.
