This video shows how you can test glow plugs with booster cables (starter cables) and wire.
The brief description that follows, helps explain why your vehicle doesn’t start easily when cold, and why we need to test the glow plugs…
Petrol engines start with the assistance of a spark from a spark plug to ignite the fuel. Whereas diesel engines start using the compression of the fuel mixture. However, diesels don’t like starting when cold. Hence diesel engines are fitted with glow plugs that heat the air fuel mix to aid starting when cold.
If a diesel engine is running well and starts easily when the engine is warm, but won’t start when cold, (or takes ages to get it started when cold). It could be an issue with the glow plugs, the glow plug system (module, relay, or voltage supply). This video shows how to test glow plugs without a multimeter (test meter).
The following table gives examples of the test equipment, tools, etc you can buy to fix your vehicle. If you’re not sure what you need, sometime it’s worth having a look? The list below may give you an idea of what’s what’s available, what to look for and how much it costs…
