2006 Head gasket replaced @ 28,000 - Diesel Forum

moabtj · 10-15-2006, 11:47 AM

Anyone Else have this problem????
I have a 06 super duty, It has been in the dealership 4 times now for overheating, and The dealership has just add antifreeze back into the degass bottle, I have told them about the TSb that was out but they insisted on the faulting cap 3 times. The truck always overheats when pulling a heavy load over a grade. Finally I went into the dealership with a 25,000lb load on day and got the tech to go with me. I got the truck to overheat, after he again put 1 gallon of antifreeze into the truck. The head gaskets are blown, My question What else shouls they be replacing????

TSB from FOrd
Coolant Expelling From Degas Bottle:
Trucks built with the 6.0 PowerStroke engine may exhibit coolant loss, low coolant, or coolant blowing out of the degas bottle. First, ensure the coolant level is not too high and the expulsion is not due to normal expansion. The coolant level in the bottle at normal operating temperature should be at the MIN mark. 2005 trucks should be checked to see if recall 05B32 applies to them.
The coolant bottle cap should be checked to see if it is capable of holding 16 PSI, and it is sealing properly on the coolant bottle. Pressure test the cooling system to verify there are no leaks. Note: It is advised to either disconnect the right exhaust manifold from the right side turbo Y-pipe, or to raise the rear of the vehicle and remove the EGR valve to check for an EGR cooler leak. Failure to do so may result in a hydralically-locked cylinder. Repair any leaks as necessary.
Inspect the coolant for oil, which would indicate a leaking oil cooler. Check the engine oil sensor reading against the coolant temp sensor. An EOT that is 25 degrees higher may indicate a failed oil cooler. On Econolines, if the engine oil cooler is replaced, the heater core inlet hose should be replaced with part 5C2Z-18472-AA, which includes an internal restrictor. If oil is present in the cooling system, the system will have to be cleaned using a solution of 1/2 cup low-sudsing liquid dishasher detergent to six gallons of water, possibly up to three times. Flush the system afterwards with clean water.
If the coolant expulsion occurs under high load conditions, suspect head gaskets that are leaking compression into the cooling system. It may be necessary to test drive the truck with a pressure gauge TEE'd into a hose and the cooling system sealed so it will not vent to verify over-pressure. When replacing the head gaskets, it is necessary to install new head bolts--they are not reusable. There is a revised torque sequence and specification for the head bolts. The head gasket kits have been revised to include parts needed in the service, but the gaskets themselves are not updated. Recommend using kit 5C3Z-6079-B, which includes all parts for both sides of the engine and covers 2003-2005. You will have to purchase the two intake manifold to head gaskets, oil filter, oil filter base o-ring, oil vent tube o-ring and heater pipe to timing cover o-ring seperately. Note: The turbo should be checked for sticking/overboost to prevent reoccurance of the head gaskets blowing.

my 2004 went at 66k, it didn't overheat, but it did blow out the antifreez. i found the EGR cooler leak blew out more antifreze than the head gaskets.

Could you clarify what you mean by 25000lb load? Is that a gross combined weight...or a trailer weight?

OMCUSNR · 10-15-2006, 04:16 PM

And, would you please add the truck & all the mods in your sig? This allows us an opportunity to give some sound advice, or pinpoint an area of trouble.

Wow.

Do you feel that an F-250 should pull a 25000lb trailer up a grade without overheating?

8" lift, 37" tires, 25,000 lbs load

Hmm...I wonder

BigDaddyT · 10-16-2006, 03:50 AM

Why lift the truck if your gonna pull with it? Just doesnt seem like something to do to a work truck. Seems like it would compromise everyones safety as brakes are intended to work with the proper sized tires. Big loads + Bigger tires is a bad idea. Specially since the load is way over what the truck is rated for. Very high probability to get severe brake fade in a panic stop.

For the money you spent on mods you coulda got the truck that was intenended for that kind of load.

Diesels arent really sposed to overheat. They have (maybe HAD would be better) very low heat rejection compared to gassers. Ive towed with oversized tires and didnt have a problem. Though I wouldnt consider pulling 25k with oversized tires. Way too much stress on the components.

If you are overheating there is a way to slow that down. Less footfeed. If I think there is gonna be a problem Ill slow down to 45 and turn on the hazards.

A better question is what else should you be replacing?? And the answer is, your truck, with one intended to pull that kind of load. A 25,000lb load + the weight of the truck, puts you up around 32-33,000lbs. Even the F350 Tow Boss isn't rated that high. You need far more truck than you have.... In all liklihood, getting the right sized truck would solve your overheating problem.....

Yes,

I have an 2002 with a *' lift 37" tires Stock gears and a chip with 160,000 miles that pulls that same trailer around everyday, the only diferance is that it has a payload of 29,332 gross. Yes I just put a new tranny in it about 10,000 ,miles ago (1st one)

First,
Just because you can get a load moving with your truck, doesn't mean you should use it to pull that load. Your F250 was not designed to pull that much and it's not safe to do so. I again reiterate what I stated before. The first thing you need to do is replace your truck with one that's designed and intended to pull that much weight. The mere fact that you are overheating while pulling this load is evidence enough that you are using the truck beyond it's design limits.

Second,
You will notice this thread is now in the U&A section... I guess you just forgot about your post in this thread. Since your truck has a Hyperpac box on it, this topic belongs in the U&A forums.....

The truck should be capable of running at 90-95% load WITHOUT overheating. Weight doesnt matter, engine load factor does.

DTRAIN · 10-26-2006, 09:18 AM

Yeah dont feel bad my 06' has been in the shop 9 times for oil leaks with only 9,000 miles on the clock. Head gaskets and Rocker gaskets twice. I dont know what to do with it anymore. It seems everytime the dealer touches it the truck gets slower and slower. I would like to add a programer but this thing wont stay together stock.
