My 05 6.0 started smoking horribly the other day with some hesitation while driving,and started to overheat.We can smell antifreeze and its losing water but cant find where from. There is no service lights on at all just saying water in fuel. any ideas? and where can i find the cheapest parts or overhaul kit if i need to do that?Any suggestions would be greatly appreciated!!!!

 

this happened to mine and it ended up bein the egr cooloer. bad bad white smoke from pipes. fill up the overflow and it goes away til the water is gone again as well as overheat and lose all power in the engine.

 

also, is there any mods on the truck??

 

Do you have access to a scanner? Check your eot ( engine oil temp) and you ect ( engine coolant temp) sounds like you got either a clogged oil cooler ( which leads to blown egr cooler)

 

Don't even bother man, he feeds off of attention, we have reasons for loving our 6.0, he has reasons for hating them, him.

As for the OP, don't start reaching for the toilet paper yet. Is there a possibility of a blown head gasket? Yes, but not always, as gauge1325 said it is possible that it's either your EGR or oil cooler (maybe both ) but if you don't get it fixed in time then it can definitely lead to a gasket failure. Both of the coolers (and HG if you feel frisky) can be done in your driveway with a little time and tools. If you are in an area that does inspections, I recommend an upgraded EGR cooler (Sinister and BulletProof have good quality and warranties) and a new oil cooler since you will have the engine torn pretty far anyway it's only another 30 minutes or so in each direction (tear down and build up). Also if time and money permits, add a coolant filter and do a full flush (flush before the teardown, filter after). Also invest in some gauges (coolant temp, oil temp, fuel pressure and EGT at a MINIMUM). If you are handy with your hands and have a fair selection of tools then doing all of the work yourself (including ARPs and a couple other upgrades) will set you back around $3k, if you have a shop do it then you're looking in the neighborhood of $6k without the guarantee the heads will be machined true.

 

Back to the question. There is a easy way to check the egr cooler just pull the egr valve in the front of the engine and if it looks all nasty black and wet in there and smells like coolant its most likely a egr cooler. We have been blocking off all our egr coolers on our trucks with freeze plugs that fit in each end of the exhaust side of the egr cooler. Its cheap and easy and we havent had any problems with them ever again. Just make sure thay are a snug fit. Before u get that far in the motor i would make sure your not having oil cooler problems also usually the coolant turns all white and nasty in your degas tank but thats hard to tell when there is nothing in here. But there should be a way to test it other than that.

 

Did you blow a belt?

 

We need more info about the truck, hard to narrow it down at this point, but the guys have hit most of the common points.

 

"Water in fuel light" - Could be injector cups?? but defiantly have larger issues. EGR likely but the torque to yield head bolts are almost as common of a failier expecially if you work it hard. ARPs are a 6.0's best friend then find a nice trash to stuff that EGR cooler in.

Like said above. Pull EGR valve and look for coolant. Head gaskets are almost impossible to confirm. (never a bad gasket, always stretched bolts) Scan tool to see if oil cooler blocked or working.

 

You have to do an EGR delete and change head studs on these.
