How to Replace a Parking Heater Glow Pin: Step-by-Step Guide
Is your parking heater refusing to start? A faulty glow pin (also called a spark plug or ignition plug) is one of the most common problems. The good news? Replacing it is a straightforward DIY job.
What Does a Glow Pin Do?
The glow pin heats up to ignite the fuel in your parking heater. When it fails, there’s no ignition, which means no heat.
Tools You’ll Need
- Socket wrench set
- Multimeter (for testing)
- New glow pin (compatible with your heater model)
- Work gloves
