I can tell you from Experience, that's not a true indicator yet. You need to get your thermostat replaced. Mine was running 13-14 out too. I replaced the thermostat and mine were within 10. All the 'good' mechanics on this forum reminded me that my test was invalid until I replaced the thermostat.

A good mechanic should see this right off the bat.

Good eye, 99. Even if it was a valid test, 14 degree delta is no reason to replace the oil cooler.

Yep 183 is not even up to temp , 190 to 195 adverage running temp .

No leaks whatsoever under the truck. Wouldn't a bad head gasket leak coolant? Also, there is NO white smoke.

Also there is oil in the degas bottle. Doesn't that point to OC failure?

If it blows a little white smoke on startup, that's a sign of ehr cooler rupture. If you pull the egr valve after parking nose down overnight and the intake is wet, this points to ash egr cooler. If neither of these, I would walk away unless I can prove it has too much coolant in it.

The green and dirty coolant is a concern. The green coolant is not original. I know of no ELC EC-1 coolant that is green. Someone has likely changed the egr cooler and put the green stuff in. Most garages that know the 6.0 will not use the green stuff. If the oil cooler with be r&r, that will alieve most of my concern of the green coolant. If you buy the truck, DO NOT CHEAP OUT on the coolant chemical flush. Flush BEFORE the oil cooler r&r ( unless it is blown). Use restore and restore plus. Get that system clean.

Oil in coolant could be from a ruptured oil cooler. Green coolant suggests less than perfect maintenance. They are asking for perfect truck price for a truck that has some problems. May have to suggest walking on this one at that price.

I would think that's why he recommended replacement.

oil in the degas is a DEFINITE walk away from this 'deal' if it were me. The amount of flushing you have to do with Simple Green, and then VC9 and the proper procedures you have to follow which it looks like almost no one ever does unless they do it themselves. It takes an entire day to properly flush your motor and you obviously can't do it BEFORE the oil cooler replacement because it would never work... Man, that would be a nightmare. You could get some guy that does a half flush without removing the block drains and sets you back up with a cooler that will fail again in a few months. I wouldn't be taking a bet on that unless I was getting that truck for a very cheap price. I would be looking to pay less than rough trade in value. Even then, it wouldn't sit good with me.

A hg failure would not typically be leaking externally.

I would walk on this one. Things to check without gates in looking for a 6.0

1. Clean coolant system .... Points to poor maintenance
2. Exhaust blowby from oil fill tube
3. Coolant coming out the degas bottle
4. Slow hot start
5. Rough cold start ... But thus could just be glowplugs
6. Dirty oil
7. Dirty tranny fluid.

You have a few on the top. I would walk .... Especially for that price. Maybe someone sold it for a reason.

There is a reason you can find green coolant and have it be ok.
If someone put the Additive package into the gold it will look
somewhat green.

You need to get that T-star replaced and then rerun the temp test.
A low ECT will mess up the temp spread.

You need to run a pressure test on the cooling system to tell
is there is a leaking head gasket or not.


I think on this truck I would give the low offer and see where it
goes. That way you can pay for the repairs yourself and not have
to pay the dealer to pay for it and then recover the loss from
the sale to you.

Just because you know the guy does not mean that he will not act like
a used car dealer.

Early model year EGR coolers rarely fail, but it is certainly possible.

I agree w/ the statement above - don't go for it unless you get a good price and have $5k + in cash for repairs.

If Ford's SCA is added to the Gold coolant, it can turn a green color.


Also -
While it is true that you need to get the ECT up to 190 for a proper test on the oil cooler efficiency, if you have a differential of 14 degrees BEFORE you get the engine up to temp, there is a problem. Oil in the degas "seals the deal". With failed oil coolers, I have seen several times ECT's that do not get up to 190. Seems that the sludge can insulate the ECT sensor.

So,, it's over $17k, for an early model Dually? No way. He prob paid 6-7k at the auction. Maybe as high as 10. But doubtful. That's way too much $$$$$. Have you been shopping for very long? There are much better deals out there. I bet you can get a studded one for less than that.

How much oil is in the degas bottle? Is it just droplets floating or is it a creamy mix? It's possible that the oil cooler was replaced and that the system wasn't flushed properly. Regardless, the truck would still be a no go for me, especially at that price. It would have to be mechanically perfect and it's far from that.

The oil in the degas was basically just a thin layer/film on top of the coolant. Also the truck does have a slight amount of blow-by when you pop the oil cap off. The mechanic said it was a "normal amount" from his experience, then showed me a truck they were getting ready to work on that had an ALARMING amount of blow-by...it was puffing out like crazy!

The truck did not start rough the day I test drove it (cold start)...fired right up. Yesterday at the shop, the mechanic fired it right back up after we got back from a drive (truck warmed up), so no apparent startup issues.

Appreciate all the responses...at this point I'm not sure this truck makes sense unless they come back with a good offer on my truck and the price is right given the issues that need fixed.

Look to see if anything like the waterpump or rad was replaced. It could be oil left from a sloppy techs part change and there was oil left in the drain pan. I would never give a used car dealer the asking price, no history, no REAL warrenty and no remorse on the troubles you get stuck with. Figure 6k in real life repairs once the troubles start
