Unknown loss of coolant

[silver6o]

I have a 2006 350 6.0 with about 42k miles. Iv had it for about 2 months now and since then Iv had to add about 6 gallons of the 50/50 mix.(this cant be the norm) I plan to take it to the dealer shortly but wanted to ask what could be causing this?

I cant find any leaks of any kind and theres no residue around the reservoir cap of any kind. Some friends told me that these engines can burn coolant and when it does you will notice white smoke from your tail pipe. I have noticed a little white smoke, but only when its cold, and isn't a lot.

The only mods I have is 4 inch TB with a muffler and no cat

Any thoughts?
thx

If you are having white smoke coming out of the tailpipe, it could possibly be the EGR cooler.

head gaskets

Most likely it is EGR Cooler. I had mine replaced last winter.

it will depend on the dealer. some are mod friendly, some aren`t. if they want the work, they won`t complain....


try talking to them first, ask questions how they feel about diferent mods on the truck. there reaction should beable to tell you whether to take your truck there or not...hope this helps

Exhaust usually isnt an issue on 6.0L's. Unless the dealer is really nasty..
