What would you do?

[colberjs]

I have an '06 6.0 Superduty with 165k on the odometer. I pull 11-12k lbs on a daily basis. With this weather we have been having (day after day of 100*+ temps) it has been running tremendously hot (I've seen 207* on my gauges). I know it is in dire need of studs, gaskets, oil cooler, EGR delete, etc. I've put 90k miles on it since I bought it 3 years ago and I still owe $19k on it.


So my question is this, should I:

A- Drop the money on this truck to Bulletproof it and stud it and probably end up putting a tranny in it along with whatever else needs to be done to make it reliable?

B- Buy a gently used 6.4 and have the power and shift-on-the-fly capability of the H&S system?

C- Buy a brand new 6.7?

Looking for opinions......

I'd get a 6.4 or a 6.7, I did the whole bullet proof thing to my 6.0 and I still have problems with it. As soon as I can afford a new 6.7 I'm trading mine in.

First, relax. 207* is perfectly fine for a diesel (especially if towing) and it probably is happier there than at 190*. The important question is what is the temp delta between the coolant temp and oil temp. That is extremely important to know as that's how you monitor the health of the oil cooler.

Delete the egr if you can. If you can't get a Bulletproof Diesel egr cooler. Flush the cooling system real good and replace the Ford coolant with a Cat EC-1 rated ELC coolant. Do that and you will have gone a long way toward fixing the reliability issues of the 6.0. Other things that are known to be failure points are the FICM, the STC fitting on the HPOP, Dummy plug and standpipe o-rings on the HPO system. An edge Insight CTS or CS will let you monitor all of that stuff so you can see a problem developing and deal with it before it leaves you stranded somewhere.

I wouldn't bother pulling the heads off unless the head gaskets go. If that happens, stud it, use the stock Ford head gaskets, and take the heads to a machine shop to make sure there are straight, no cracks etc. Have bronze valve guides and hardened valve seats installed and the max that can be shaved off the deck to square them up is .008".

All the issues and fixes for the 6.0 are well known and documented at this point. I wouldn't trade mine for a 6.4 or a 6.7. If you are willing and capable of doing your own work everything I suggested can be done for about $1000.

PGreen...can you change the STC fitting without removing the intake?

I love the looks of the 6.4 over the 6.7 but 6.7 is awesome

It is tough because you have to remove the IPR to get the HPOP out and there isn't much room there to play with.

Jesse at 207 towing 11k pounds in 100 degree heat you are exactly where you should be. No worries.

[2006PSDSD]

I wouldn't worry about your temps like the others have said

[colberjs]

That makes me feel a lot better about the temps. But when they hit about 200 and up I smell coolant really bad in the cab. That's not normal is it? That's what made me think my gaskets were going bad.
