6.0 Engine Flush

[olgoat]

I did a search for info about an engine flush but haven't come up with anything. I bought this truck used with 94000 mile and don't know how often the previous owner changed the oil. The truck runs great, but I thought a flush may help clean out any deposits, especially from the oil cooler and injectors.
Any suggestions or thought are appreciated.

Thanks,
Lonnie

I think i seen a post on here about induction cleaning the dealers offered. Its pretty expensive but apparently people said it made their truck run like new. Their was 2 different ones. One just cleaned the injectors i think and was cheaper the other one cleaned a lot more but was pretty expensive. Wouldnt hurt doing some research and seeing what you can dig up.

Heres a good article as to why you should do an engine coolant flush...

I would absolutely recommend NOT flushing the crankcase on a Powerstroke, especially a 6.0. 94k is nothing even on one that has been slightly neglected. more than likely, there are no crankcase deposites anyway. just change the oil every 3500 to 4500 miles with a high quality synthetic blend motor oil, and use only motorcraft filters,it will last you many years, except for the head gaskets, lol. but that can be fixed

Thanks for the info.
I've been using Shell Rotella T Synthetic 5w 40. I was using after market filters until I did some research and found that a mistake. But I did find that Motorcraft, Racor and Fram filters are the same, I visually looked at all three, they even have the same patent number on them. I understand that they are all made by Racor. I've purchased an EGR delete kit and a by-pass oil filter, I'll put them on when the weather warm up.
I also understand that the type of coolant is important, how do I tell if it has the right type (Propylene Glycol)?

Thanks Again,
Lonnie

On and older engine the synthetic oil will be like a flush, Exxon tech informed me once that its the first oil change from conventional oil that realy could dirty your filter. So my vote is a synthetic oil if you realy want to clean her. I changed my filter early when I did put in Synthetic last year.

All Motorcraft filters for the Powerstroke are made by Racor. the recommended coolant is actually ethylene glycol -HOAT formula. you should use Zerex G-05 or Motorcraft gold coolant. the coolant should be an amber color.

Thank you Robsr, I found the Zerex G-05 at O'Reilly's. Guess I'll pick up some to have on had when I install the EGR delete kit.
What is the best way to flush these engines? And how much coolant does it take?

The system holds aprox. 27.5 qts. Drain radiator, then pull the plugs in the side of the engine block, these are 8mm allen head toward the rear of block. you'll need to pull the starter for easier acc. to the RH side. its a messy ordeal, but there will be at least two gallons plus a lot of sediment that can be flushed out by doing this.

We've noticed less sediment trapped in coolant filters we've installed on trucks that had this procedure, so I would say your oil cooler will love you for it, lol. have fun
