Paul,
Have you checked/replaced the thermostat?
BTW, when I replace a thermostat, I prop it open with an aspirin. That
way when I fill up the radiator, it fills the entire system. Once
started, the aspirin dissolves and the engine feels better <G>.

Subject: brain dead... over heating? but gauge is fine!
OK.... I'm sure you're all sick of my brain-dead
thinking as of late... but....
on my GT6 MKIII....
compression per cyl = avg 165psi
Temp gauge works fine. (new mechanical dual press temp) Thermostat=180
degrees Sparkplugs look fine (mixture good) Champion N12YC 13lbs
radiator cap 50/50 mix anti-freeze. (Maybe closer to 60/40 60=water)
So why would the car ...cruising down the highway
start ejecting water out the overflow bottle?
Enough so that it started spurting out the little
lid breather hole and 'geyser-ing' against the underside
of the bonnet. (water all over the place near the bottle)
I used a mechanical 'cooking' thermometer to check the head, radiator,
and back side of the waterpump/head area temperatures. All were below
185 degrees F.
Should there be some air space in the cooling system
to allow for expansion? I though that was the purpose
of the radiator cap design. To allow it to loose coolant
to the bottle, and then suck it back in as it cooled.
comments? wise-cracks? are all welcome
