What is the Glow Plugs all about?

Diesel fuel is self-igniting under pressure. However, very cold temperatures can prevent ignition. This is where glow plugs come into play. Unlike spark plugs, which create an arc of electricity, glow plugs preheat the cylinder so the fuel can ignite more easily. The electrode heats up, glowing like the filament in an incandescent light bulb, and provides the necessary assistance to ignite the diesel fuel.

Keep in mind:

Removing glow plugs from many vehicles can be difficult and labor intensive.

How it's done:

The vehicle battery is disconnected
The defective glow plugs are removed
The new glow plugs are installed and wiring is connected
The battery is reconnected
The glow plug system is checked for proper operation and the vehicle is road tested for proper operation

Our recommendation:

The glow plugs will eventually fail and require replacement, though not at any specific interval. It may be necessary to replace the wiring harness, the glow plugs, and the relay that controls the glow plugs. In some vehicles, the relay actually fails more often than the glow plugs. If you suspect a problem with the glow plugs on your diesel engine, have one of our expert mechanics inspect and replace them as necessary.

What common symptoms indicate you may need to replace the Glow Plugs?

Hard/slow starting in cold weather
Not starting in cold weather (barring battery or other equipment failure)
More smoke than usual when starting (exhaust)
Misfire on a cylinder until the fuel warms up enough

How important is this service?

Glow plug replacement isn’t like replacing spark plugs, and some diesel owners can go for 100,000 miles or more without changing them. The relays fail more often than the plug, which is another reason it is very important to have the problem diagnosed by one of our expert diesel mechanics. This will ensure that you’re fixing the underlying problem, rather than just addressing symptoms, saving you time, money and headaches.

Mercedes-Benz E320 V6-3.2L - Window Regulator Replacement (Driver Side Front) - Houston, Texas

My experience with Joseph has been mixed. He repaired my window regulator and currently the window is operating properly. When I inspected the car after he completed the work, I noticed a hole in my door panel that was not there before. When I asked Joseph what happened to my door he said that the panel piece broke when installing the door panel. He told me that it wasn't a "big deal" and "its was old" I told him that it was a big deal and I don't drive around with even a scratch on my car. He said again that it wasn't a big deal and that I could glue the piece together. The piece was in several pieces. My son came and took a picture of the hole in the door panel with his phone and sent it to his dad. Joseph did say that he ordered the damage piece and that he will back in a couple of days to replace the piece. I called my husband about what happened.He tried to Your Mechanic to report the situation but was not able to talk to anyone and remain on hold for some time until he disconnected his call. He never talked to a representative to report the damage.
