Hi all,

I have a 2009 6.0 E350 just purchased from Ryder. I have read about and seen the horrors on TV about the EGR failures. Dose anyone know if my truck is one of those affected or has Ford fixed the issue by the time mine was built? The mileage is 158K.

Thanks,

Any truck equipped with an EGR system can potentially experience a failure. That being said, the later model year trucks experience a much lesser failure rate in my experience. Each truck is different and it can come down to the luck of the draw.

 

That isn't really true from what I know. The earlier round EGR coolers had a better record then the later square ones. You most likely have the newer square one.

If you keep track of the ECT and EOT and replace the oil cooler before the temp difference exceeds 15 degrees the factory EGR cooler may last a long time.

If you don't keep track, or the temp difference starts to exceed 15 degrees while riding down the road at 65 mph you are most likely going to have an EGR cooler failure. When you get here you will need a new oil cooler and an EGR cooler/ EGR delete kit.

If you are going to repace the oil cooler get one from Bullet Proof Diesel.

Hope this helps.

 

Thanks guys! I am new to diesel and don't know what the ECT and EOT represent. Also, can you tell me how to monitor these? What should the cost be to have the oil cooler and EGR delete done in a shop?

Thanks Again,
Dick

 

here you go, the only OEM replacement bulletproff stuff

BulletProofDiesel - Darn-Near Bullet Proof Diesel Products for your 6.0

 

ECT = Engine Coolant Temperature
EOT = Engine Oil Temperature

The delta, or difference between the two temperatures should be no more than 15 degrees when the van is operated at normal highway speeds and level road.

You can monitor both with something such as a ScanGauge II, available online and at places like Advance Auto and Auto Zone.

The 6.0 is slightly detuned in the E-series vans, so they don't experience some of the extremes that pickup owners experience. But EGR cooler failures are not unheard of in the vans. Getting to the oil cooler and EGR cooler involves taking out the turbo and other parts. The big cost is labor, not parts.

 

Thanks guys, I will look into your recommendations. As for the type of driving I will be doing mostly will be local but occasionally going from Lexington, Ky. to Newark, Delaware through the mountains of Wv. and Maryland. Would it make sense to monitor the two temps and if they are getting far apart to slow down or stop for a while to cool down? or is it too late by then?

Remember that the 15 degree delta is at speed on level road 65 mph no wind or temp extremes.
When you hit those long uphill grades and mountain passes that the engine may or will not maintain that 15 degree difference.
Keep your EOT under 230 degrees and the ECT below 220 - you can do that by keeping engine rpm at or under 2200 rpm which means that you will have to slow down on those hills.
If you see it going above those temps you might want to pull over and take a short break.

Of course there are those 6.0 owners that will tell you that you can exceed these numbers and that they have done so without harm to the engine. Don't do that.

 

Thanks! Do you recommend shutting down the engine or just letting it idle for a while? I plan to buy a Scan Gauge II today so I can monitor the EOT and ECT.

I am an older fellow and have plenty of time and patience so it should not be a problem.

 

Normally I just shut it down around town.
But after a long uphill grade with real hot temps I'll let it idle for just an extra 20 seconds, maybe less after coming to a rest stop.

 

No. The 15 degree delta is under load. The tsb says to drive the vehicle under wide open throttle/high load to achieve maximum boost. As far as keeping your EOT under 230 and ECT under 220, that is silly. The cooling fan does not fully lock in until 219 degrees.

 

Quite hilarious! Love it!
Does the tsb recommend any particular dry lake test bed for running at wide open throttle?

I think it answers some of the OP questions and more.

 

Wow, lots of different thoughts! I appreciate all of your input and am somewhat confused but will take all into consideration. I wonder if I did the right thing by buying this rig!

Seems like no one likes to work on the vans! Can't blame them for that I guess but there are a lot of them out there. Maybe that's why Ford stopped offering the diesel in them.

I just ordered the Scangauge II from Amazon so we will see what happens when I get it in and working.

Merry Christmas to you all! I will keep posting.

Thanks,

Dick

 

I'll agree the newer TSB in regards to oil cooler testing is extremely vague in what they are referencing in going WOT and taking a reading... I do see their point.

The older TSB referenced holding 65mph for a certain distance (6 miles?) and the temp difference should be no more than 25 degrees. Then the newer TSB came out and referenced the above 15 degree at WOT.

FWIW I see 0-2 putzing around town. 2-4 45-55 mph, around 6 @ 65mph and 6-9 at a steady 75-80 mph.

The only reason Ford quit putting diesels in E-series vans is that the 6.4 wouldn't fit, and the development required to put the 6.7 in a van that was on its way out of production didn't justify the cost.

The E-series replacement, the Ford Transit, will have diesel power as an option.
