Comments about CARQUEST by BWD Diesel Glow Plug Relay:
I have a 2001 excursion that was getting harder and harder to start during the winter. I had codes P0672, P0674, P0676, and P0678. Checked the wiring harness and glow plugs, no issues found. I swapped electrical connections on the GPCM and instantly got codes P0671, P0673, P0675, and P0677. The GPCM from advanced has worked perfectly since installing.

Q:where is the glow plug relay located & how to test it on my 2003 7.3 power stroke
A:Hello Jerry. There are a few relays that are near each other. Also there are different ways to test a relay. Because there is a risk of damage we suggest consulting a repair manual or a certified mechanic.
Q:Its 40 degrees out and I have to plug my ford f250 6.0 diesel in. If I replace this part, will I still have to plug my truck in?
A:The glow plugs are energized based on the engine oil temp, air temp and altitude: At 30 degrees air temp the plugs heat for 120 seconds; 60 degrees, 60 seconds, 100 degrees, less than 10 seconds. You can check if the Glow plug relay (BWD Relay - Part No. R6036) is bad with a Voltmeter. If this relay passes the test it is good or else you will have to replace it. If you replace the relay and still experience hard starts, you will need to move on to testing the glow plugs themselves. There are a couple ways to test the glow plugs, you will need either a test light, or a good voltmeter that will read in ohms.

Q:where is this relay found an the truck
A:We will need more information including the year, make, model, and engine size of your application before we can make a suggestion.
Q:Where is the BWD relay located on a 2005 Ford F-350 6.0liter diesel? If this part were bad, would that cause rough, smokey starts?
A:It should be right up on the manifold.
Q:where is the BWD relay located on the 2003 ford 250 6.0 diesel?
A:If you take off the air filter it should be located under the air filter and should look like a ford starter solenoid.
A:Actually the previous answer applies only if the vehicle is equipped with the "federal emissions" model relay. For the "California emissions relay" which this part fits, it is bolted to the top of the passenger side valve cover. I have the same exact vehicle and have recently replaced this part.
