How To Check Glow Plugs On 6.6 Duramax

Glow plugs are small heating elements that are used to help start diesel engines. They are typically checked by removing a connector and testing for resistance. The proper resistance should be around 8-10 ohms.

How To Check Glow Plugs On 6.6 Duramax

To check the glow plugs on a 6.6 Duramax, you will need to remove the engine cover and locate the eight glow plugs. You can then use a test light or voltmeter to test for resistance between the plug’s connector and the engine block. A good plug should have around 12-14 ohms of resistance, while a bad plug will have significantly more.

Frequently Asked Questions

How Do You Test A Glow Plug Without Removing It?

There are a few ways to test a glow plug without removing it. One way is to remove the spark plug and hold the glow plug wire against the metal part of the engine while someone else cranks the engine over. If you see a spark, the glow plug is working. Another way is to remove the air cleaner and hold a light up to the glow plug while someone else cranks the engine over. If you see a light, the glow plug is working.

How Do You Check Glow Plugs On A 2005 Duramax?

There are three ways to check the glow plugs on a 2005 Duramax: visually, with a test light, and with a scan tool.

How Do You Test Diesel Glow Plugs?

The most common way to test diesel glow plugs is by using a glow plug tester. This is a device that attaches to the glow plug socket on the engine and measures the resistance of the glow plug.

How Do You Check If Your Glow Plugs Are Working?

There are a few ways to check if your glow plugs are working. One is to start the engine and see if it’s hard to start or not. Another way is to remove one of the glow plugs and see if it has a good spark.

How Do I Test My Duramax Glow Plugs?

Testing glow plugs is a relatively simple process that can be accomplished with a multimeter. By measuring the resistance across the plug’s connector, it’s possible to determine whether or not the plug is functioning properly.

How Do You Test A Glow Plug With A Multimeter?

To test a glow plug with a multimeter, you need to set the meter to read resistance. Touch the probes of the meter to either side of the glow plug. If the meter reads zero resistance, the glow plug is good. If the meter reads a high resistance, the glow plug is bad.

How Do You Check Glow Plugs On Diesel Engine Without Removing?

There are a few ways to check glow plugs on a diesel engine without removing them. One is to remove the air filter and look at the glow plugs. Another is to remove the valve cover and look at the glow plugs.


Wrap-Up

There are a few steps that can be taken to check the glow plugs on a 6.6 Duramax. The first is to make sure that the engine is cold, as this is when the glow plugs are used. Next, locate the glow plug relay and remove the cover. There should be four connectors coming off of the relay – two for the positive and two for the negative. Use a test light to check each connector for power. If there is power at any of the connectors, then the glow plug is working. If there is no power at any of the connectors, then the glow plug needs to be replaced.
