Woody, The coolant bottle cap should release at 15lb's if it's the correct
one.

Hi, All,

I'm afraid I have a coolant pressure problem (too high) and am hoping
one of you will have a possible easily fixed cause, other than blown
head gasket.

After having the coolant bottle cap blow (on my new SS bottle), I put
a pressure gage on the cooling system.  With engine not running, I
pressurized the system to 15 psi. It held steady at 14.5 psi for over
2 hours.  Thought I was home free.

I then started the car and watched the pressure rise slowly to 20 psi
before shutting off the car and doing possible damage.  This does not
seem normal.  My manual does not give much info; however, I may be
missing pages on this subject.

The car sat for 5-6 years before I bought in on e-bay a little over a
year ago.  At that time, I replaced all fuel system components,
flushed the fuel lines, removed & cleaned the fuel tank, replaced all
coolant hoses, and went thru the brakes.  After clicking the starter a
few times to get the fuel pump to prime the system, the started almost
immediately and seemed to run normally.  However, on my first drive,
the plastic coolant bottle burst at the normal burst point.   A few
days later, I started a new job and shortly thereafter met a special
lady, so I haven't had time to work on the car again until recently.

Am I being paranoid about the pressure rise?  Should I systematically
remove spark plugs to see of the pressure stabilizes below 14-16 psi?

Thanks in advance for your help.

Woody

p.s., Yes, I'm still dating the lady!
