How To Replace The Glow Plugs On A VW 2.0 TDI Diesel Engine

Glen Soto

Glow plugs are needed to heat up combustion chambers in diesel engine to make the vehicles easier to start. Diesel isn't as volatile as gasoline and the heat helps it to become combustible. A faulty glow plug won't be able to heat up the chamber and it will be much harder to start your vehicle; especially on cold days. You need to replace the glow plugs to get your vehicle to start up quickly on cold mornings. Here is how you as a car owner can replace the glow plugs on a VW 2.0 TDI diesel engine.

Disconnect Battery

Remove the negative terminal on the battery. This will stop the flow of electricity through the electrical system so you don't get shocked and the electrical system doesn't get damaged.

Remove Glow Plugs

The VW 2.0 TDI diesel is a four cylinder engine. Glow plugs are used in place of the spark plugs used on gasoline-powered cars, but they are both positioned the same way in the engine. In the VW engine, there are four glow plugs (one for each cylinder) located along the front of the engine. A set of wires carries the electrical connections to each plug. The set of wires is attached to the front of the engine.

Follow the wires to each plug and pull the connection off of the plug. This, again, will be like pulling the wire connection off of a spark plug. You are going to need a 10mm socket with a 10" ratchet extension to reach the head of the glow plug. Place the socket over the head of the glow plug and turn it counterclockwise. Most times, the glow plug will stick in the socket and you can carefully pull it out of the side of the engine, but sometimes you'll need a pair of needle-nose pliers to reach into the slot and grab the glow plug so you can pull it out.

Replacing Glow Plug

Place the glow plug into the socket and slide it into the side of the engine. Turn the plug clockwise. You have to be careful turning the glow plug. The glow plug is hollow and if you turn it too hard, you'll snap it. Replace the wire connecter and move to the next glow plug and repeat the process.

Once all the glow plugs are replaced, press the glow plug button and let it warm up the combustion chambers. Your VW should start right up now. For assistance, talk to a professional like Bethel Automotive.
