Frequently Asked Questions (FAQs)
1. Do cheap glow plugs work?
Cheap glow plugs may not have the required capability and can potentially do more harm than good to the engine. It is advisable to invest in quality glow plugs to avoid costly repairs.
2. Can a diesel run without glow plugs?
Yes, diesel engines can start without glow plugs. Glow plugs are not responsible for triggering the combustion process in a diesel engine. Their purpose is to warm up the fuel/air mixture to enable self-combustion.
3. Are glow plugs just for starting?
Glow plugs are not only used during cold weather start-up but also continue to cycle after the engine is cranked to reduce start-up emissions.
4. Are aftermarket glow plugs good?
It is recommended to choose quality glow plugs rather than cheaper aftermarket options. Low-quality glow plugs can swell, making removal difficult or even causing damage to the engine.
5. Can you leave glow plugs on too long?
Glow plugs are equipped with a timer unit that limits how long they stay on when the key is turned on. Continuously cycling the key can damage the glow plugs.
6. Are cold starts bad for diesels?
Frequent cold starts can shorten the lifespan of a diesel engine. Preheated coolant can help protect the engine and prolong its longevity.
7. Is it bad to start a diesel with bad glow plugs?
Starting a diesel engine with bad glow plugs can lead to fuel not igniting properly, causing misfires or poor engine performance.
8. What happens if you don't let glow plugs warm up?
If glow plugs are not given sufficient time to warm up, there may not be enough heat in the combustion chamber for proper fuel ignition. It is best to wait for the glow plugs to warm up before starting the engine.
9. Do glow plugs work when the engine is warm?
Some cars continue to use glow plugs until the engine reaches its operating temperature to reduce diesel exhaust emissions.
