Diesel Injector Cleaning

[BillChaffey]

I'm not sure if this belongs here or in Newbies, but it's here now.
While in my local Ford dealer this morning I was looking over the Glossy 3 ring binders for Vehicle maintenance it said "$169.00 for injector cleaning on your Diesel engine" Service manager guaranted better mileage & smoother running. Any of you smart people know of another name for this. I'm sure it can be done for a lot less considering the dealers mark up.

Yeah, it's called Howes Meaner Power Kleaner. Double dose for the first three tanks to clean the injectors, then regular dose in every tank after that to keep them clean.

I have used Howes in both my trucks since I bought them. A couple of years ago I was down in Alabama and a truck stop was offering something similar for around $90.00. Said it takes about 90 minutes.

There's a process where you remove the fuel lines and run external lines to and from the injectors, and run something like Diesel Purge (expensive brake cleaner, basically) through the injectors at pressure. The supply valve brings new fuel into the injectors, while the return valve processes the used fuel. The supply line usually has a small filter attached to it. Disconnect the original hoses, and attach the new hoses that are connected to the bottle. Essentially, you are creating an external fuel injector line. Dump the cleaner or the purge solution into the bottle. Start the engine, and allow it to rev to different speeds. You must change the engine speed to ensure that all areas of the injectors are cleaned properly. Replace the original parts when you have finished.

Better to use a good injector cleaner on a regular basis so they stay clean in the first place.
