'05 6.0 Fuel in Coolant.

What causes the fuel to contaminate the cooling system on a 2005 6.0. Staff states the ambulance got warm enough to blow the cap off the coolant overflow tank.

Anyone else have the same thought. Is this why the aftermarket studs are being installed when the EGR deletes are going in ?

from what i've heard (no personal experience) cylinder heads will crack in that area from
being overheated, usually on higher mileage vehicles.

if the bus was overheating make sure that problem is fixed in addtition to the heads. some will claim injector cups can cause this but it's not worth putting cups in and only having a small chance that will fix it. either way the engine has to come out.

the headgasket problem is a whole other issue not usually found in detuned e-series vans. granted the turbos still can stick causing an overboost condition but they don't generate as much cylinder pressure as the trucks

E350 ambulance with 60K miles. It's had 4 coolers put on and numerous turbo fixes. It's a POS. Fuel in the Coolant is a new one.

cracked injector cup, or a crack between the fuel rail and the coolant jacket.

That happened to me. Pushed all of the coolant out, and replaced it with diesel. I had a cracked passenger side head.

I dream of a better tomorrow, where chickens can cross the road and not be questioned about their motives.

while I have actually seen a cracked injector cup on a 6.0 head i would never recommend anyone replace cups for this concern. it is much more likely you'll end up with a repeat repair. ford does not acknowledge injector cups as a cause for this concern

remember, there is a lower injector o-ring that seals fuel from the injector cup. in order fuel to get in the coolant, not only would the cup have to fail, but the lower oring would also have to fail

I was told by a Ford Tech on here (can't recall his name) that a cracked injector cup will not put fuel in the coolant. I dunno.

On a 7.3 this is true. However on the 6.0's that I've seen it has always been a cylinder head. There is even a tsb on it. I can look it up for you guys if anyone's interested.
