Peter,

One thing you did not mention: where is the coolant which has been displaced
by the air bubble going?  Is your reservoir tank filling up?  Also, a system
pressure test done cold most often proves nothing.

<<Is there a test for Hydrocarbons that checks the coolant itself, rather than
the gas found in the cooling system? >>
Yes.
