Description
When your diesel tractor turns into a stubborn mule that won’t start on cold mornings, worn-out heater plugs are usually the culprit keeping you from getting to work. These 12-volt heater plugs provide the pre-heat your diesel engine needs to fire up reliably in cold weather, heating the combustion chamber so your engine starts quickly instead of cranking endlessly. If you’ve been wrestling with hard starting when the mercury drops, this part can save you time, frustration, and wear on your starter.
What You’re Getting
- Provides the pre-heat your diesel engine needs to fire up reliably in cold weather
- Reduces the cranking time that wears out starters and batteries
- Helps reduce white smoke and rough running that occurs when diesels start cold
- 12-volt operation that works with your tractor’s electrical system
- Direct replacement for worn or failed heater plugs
Built for Real Farm Work
This heater plug fits Case BD series tractors including the D323, D324, D326, D436, D438, and D439 models, plus the Renault Super 5D. Whether you’re maintaining vintage tractors that still earn their keep around the farm or keeping backup equipment ready for emergency use, these heater plugs provide the starting assistance that makes the difference between productive mornings and frustrating delays.
Made to Last
Quality construction ensures the plug heats up quickly and maintains proper temperature for reliable starting, while the robust design handles the thermal cycling that comes with seasons of heating up and cooling down. Since diesel fuel doesn’t ignite as easily as gasoline when temperatures drop, this heater plug provides the extra heat needed to warm the combustion chamber.
Installation Notes
Before installation, clean the cylinder head threads thoroughly and apply anti-seize compound to prevent the plug from seizing in the head. Don’t overtighten, as this can damage the plug or cylinder head threads. Test the heater plug operation after installation by checking for proper heating. A quick tip: if you’re still having starting problems after replacing heater plugs, check your electrical system and glow plug timer.
