Hey yal my name is Kody Redman just in case you don't know me. I'm ueally in the IDI section. Well anyways my other mom has a 05 f-450 dually with the egr delete rbp exhause head studs and k an n intake. She use's it as a daily driver at times but mainly for to tow her 4 horse slant living qauters trailer to her rodeos. She just had a problem with it, and some how it is dumping fuel back into the cooling section. Has anyone had this problem before. Any advice will be apperciated.

 

come on fella's please help a guy out

 

Any more info? How did you figure out it was fuel in the coolant? Never really heard of this before even with blown headgaskets, but I suppose it's possible. How many miles on the truck? Did it start losing power at all?

 

had fuel in my cooling system. Ford had told me it was injector sleeves so i said ok fix em. $1800 later got the truck back same thing,still fuel in my coolant. Drove the truck like that for about a month till the diesel started attacking o rings in the cooling system.Causing a major coolant leak. Had ford fix the o ring. So anyways long story short I just finished putting on 2 brand new heads because they were cracked, arp studs and all new o rings in my cooler. ( orings were all swollen from the diesel )

 

Spokes you summed for Mdub707. Same excat thing. And miles I'm not sure, but power she never lost a bit. It ran just fine. I thought the injector sleeves were bad in it also cause it would leek out but not sure how it would get back threw the cooling system unless by passed the water pump or some deal not sure or to bright on the new 6 ohs

 

do we got any other takers??

 

Some 2003-2007 F-Super Duty 250-750, 2003-2005 vehicles built on or before 9/30/2008 may exhibit fuel in engine coolant, due to leaks in the cylinder head fuel injector area. Symptoms may include fuel in engine coolant and or coolant expulsion from the degas bottle.

1. Drain all of the coolant from cooling system.
NOTE:
FAILURE TO DRAIN THE COOLING SYSTEM PRIOR TO PRESSURIZATION WILL PREVENT BUBBLES FROM FORMING WHEN SPRAYED WITH SOAP AND WATER SOLUTION.
2. Remove all injectors from both cylinder heads.
3. Wipe injector bore clean of oil and fuel.
4. Fit the cooling system pressure tester, I used a hand pump radiator tester.
5. Apply 10 psi of air pressure to sealed cooling system. I suggest you use a hand operated pressure tester. (More pressure ISN'T BETTER)
6. Spray a 50/50 mixture of dish soap and water generously inside each injector bore. Ensure cylinder head injector bore casting is coated with a soap layer.
7. Inspect each injector bore for bubbles. Most common area is between the two injector fuel sealing O-rings in the sealing area on the side nearest the cylinder glow plug.

If you see bubbles in any of these areas, replace the cylinder head(s).
