my 05 is due for a oil change and fuel filter change,
i am taking it to my service station, mech on duty there does great work and i do not have to worry about problems after his work.
he was so booked, i could not even get it in before christmas.
not telling you what to do, but sometimes its best to take it to someone who knows his business or let them help you through the process at least once.
does not hurt my feelings letting him do that type work, its his job, he is properly trained and does good work.
You can mess up your truck and cost you big $$$$$ by just making some small mistake.
these trucks are big and tough, but need proper maintenance.
and do not worry what someone says, just get it fixed right.
my 05, just starts right up after the heater lights go out.
let us know what you find wrong with the truck,
