VGT Owner Servicable?

[Lil' Dog]

After spending some time with my truck over the past few months putting in gauges etc. I noticed my unit has the turbo service plug installed from the factory (along with the teeny tiny Intercooler ). The question is, it there a service sequence that the owner can do to keep the VGT in good shape? I was thinking a decarborizing fluid like Snap-On sells would be what is injected? Do you need the Star-Scan to cycle the VGT during the process?



Anyway, just wondering if there was something an owner can do on his own to keep things in top shape. .



Thanks in advance

I have no idea whether it would be wise or even permissable to attempt to flush carbon out of the VGT but I would recommend talking to several experienced Dodge dealer Cummins techs or Cummins techs experienced with the ISB6. 7 to get their opinion before I would do it. It might be a great idea but it could perhaps wash carbon dust into an inaccessible crevis and cause binding and turbo failure and, if detectable might be cause to void your warranty. Who knows?

Sort of what I was thinking. . I am not out to try and take a techs job, just wondering what they invest so much time in doing on a TSB by servicing the turbo and adding this port. Most shops have de-carborizing fluids on hand for injector/engine flushes for other projects in the dealer. I just see a few fellows here that are more ingrained in the Cummins world that may shed some light on this. .

There are at least three Dodge dealer techs among the TDR membership that I know of and lots of other mechanics, both professional and shade tree, who may know and may offer advice here when they see your post.

I am not sure but think the turbo is probably removed from the engine and a detailed procedure written by Cummins and published by Dodge is used when dealer techs perform a cleaning.

It might be possible for you to obtain a copy of that service bulletin/procedural guide if you want to attempt it.

I think with the cost of the tool and and with the new software you would be spinnin'g your wheels. I see very few turbos now that need any cleaning. They have developed a new test that is run from the starscan (key on engine off)

that will tell you what is needed (after a 2262 code has tripped) software update,cleaning or replacement.

You need to be very carefull with what type chemicals you run through any dpf equipped rig... ... ...

Good info... Thanks. .

You can call Miller and check the cost, but if the turbo is drilled, here is what you need. Like Bob said, not as much need today if you have the newest flashes.

Wow. Thanks. . I was just wondering if this could be a preventative maintenance item. I know some owners that reach the 150,000 mile mark need them serviced regardless of the upgrades/deletes or not. If it could be a preventative thing, that would avoid any potential problems in the future. Are you seeing this same type of thing?

I don't see any reason why you couldn't do it as a preventative but it is not recommended unless you have a P2262. One note is the TSB says to use three cans, but most good techs use six, again assuming you have a P2262. Also having the turbo hot helps. I guess just follow the TSB as it's written and you should not have any problems.
