My truck is an 04 it doesn't have the Degas bottle that came on the 05. I looked for it reading some other threads. I was told by the dealership that they thought I was over boosting it. I have the edge insight that reads PID of the ECM and a Pyro. It said 27lbs of boost. Not sure but that doesn't sound high to me. I could be that I just not finding the Degas bottle. I have found twice now that the coolant Res. has been a gal to 2 gal. low.
what do you mean you dont have the 05 degas bottle on your 2004...
theyre all the same.
you should NOT fill the coolant degas bottle above the "low mark"...
you should ignore the YEARS mentioned on the tsb...the TSB applies
to every 6.0L
if youve been pushing coolant out the cap you WILL have white crusty
deposits on the coolant degas bottle and below...perhaps even on
the valve cover...look at the area UNDER the coolant degas bottle....
27lbs is typical boost...i see 30-32lbs (stock) !
becareful...the dealers comment about "over boosting" could be
a sign that hes setting up to void your warranty...certainly its
an indication that he thinks you have a "performance enhancing" tuner.
if youre not running a tuner or havent recently removed the tuner your
dealer should check the KAM (keep alive memory) and note the number
of engine starts since the KAM was reset...the maximum number of
recorded starts is 200+ (the dealer may choose to clear the memory
too).
