losing coolant

--------------------------------------------------------------------------------

I have been losing coolant for about 4 years now. It comes from the cap on the degas bottle, bout once a month i put about 2 qts in it. Ive replaced the cap and it still does it. Does anybody know what could be causing it. Ive read all over about radiator leaks and hose leaks and orings but I have had none of these leak. It only comes from the cap. Ive tested the air in the degas bottle for diesel exhaust with a blue point test kit and its been negative everytime. I bought this truck new in 4/2007. Its a job 1 and I did the venturi hose kit when it first came out and Im still running with original radiator. I have 61k miles. Any help is appreciated. Thx

If it' coming from the cap even after trying new ones then there's a good possibility that it's a head gasket issue. Does it do it all the time or only when under load?

I would say it sounds like head gaskets unfortunately. 4 years is a long time. You had it at the dealership at all? Do you still have warranty?
