My Aunt just got a '06 6.0 with 43000 miles. First I can honestly say that it was owned by OLD man that believed in REAL maintenance. This truck is a perfect Lariat. My real concern is that while this truck will not be her daily driver, It will be used. I was wondering if there should be anything I am should warn her about. I must admit that I am a little jealous after parking my little ranger next to this beautiful f250. Also is there a good aftermarket exhaust that is quiet? And should I take out the EGR? So many questions, but I am trying to ensure that this great lady has the truck of her dreams here and now. The really cool thing is that she is giving up her escalade. While I do not hate GM I really don't like their truck platforms. Back on point any recommendations from you the real world experts will be a great help! Thanks Gabe

 

I would take the EGR out and clean it... then Italian tune it up.

Mark in a recent thread put up the new owners to do list...

I agree with 98% of the stuff on that list.

So start there.

Be sure you identify and locate the top 2 or 3 diesel techs in your area.

Find the best 3 for the 6.0 that works at a Ford dealer (and have things like IDS handy)

and another 3 that is independent.

You are going to need them...

BTW... if I owned that vehicle.. I would be posting armed guards to prevent it from being stolen!

 

Sounds like a lucky lady.

I need to point out there is an EGR Valve (which you take out and clean)
and there is an EGR Cooler which some folks will delete (or replace)
when it fails.

Don't spend money on the EGR Cooler delete/replacement - yet!
Since the oil cooler can be replaced @ the same time while everything
is torn apart if/when you decide to replace/delete the EGR Cooler.
Depending upon where you live - state inspections may require
you to "replace" the EGR Cooler vs. delete it also.

First, decide what "needs" attention.
So, I'm not sure which EGR the OP was referring to, but I would suggest
you get an ODBII "gauge" so you can monitor the temps.
See my sig for the one I have.

The ECT and EOT (Eng coolant temp or Eng Oil temp) are very good
at pointing out whether your t-stat needs replacing (seems to often be the case) and if your EOT exceeds the ECT by 15* once fully
warmed up to 190* on the hi-way then you likely have a partially
plugged (or fully plugged) Oil cooler.

The widely held story is that most of the EGR Cooler failures are
actually caused by the OIL cooler getting clogged. So, in the
early 6.0 days, folks would repeatedly replace EGR Coolers that failed
before Ford figured out the Oil cooler was clogged and preventing
enough coolant to reach the EGR Cooler to keep it from failing...

When the oil cooler is plugged it restricts coolant flow to the EGR Cooler
which cools EXHAUST gases on their way back to the intake (via the EGR Valve). The EGR cooler sees very high temps and a reduction in coolant
will cause the factory 'solder' joints to re-flow and cause coolant to
escape into the hot exhaust and lead to all sorts of issues.
