[alfa] Re: Underheating GTV

Hi Bruce,
    What makes you sure your temp gauge is accurate?  Is it possible that the 
car really is running at 190F and the gauge is off?
    If you think the gauge is accurate, it could be that the thermostat is 
jamming in the return position (ie once it opens it has a hard time closing 
until things really cool off).  You might be able to see this if you put the 
thermostat in a hot pot of water and let it cool down.  Watch for smooth continuous 
action of the thermostat as it closes.  If you want to get fancy, you can 
even stick a thermometer in the pot.  But what's the accuracy of the thermometer? 
 I am always suspicious of accuracy of intrumentation unless it has been 
calibrated.

I have bleed the cooling system at both locations with the car on a flat
surface to make sure that any air will pool at the thermostat.  My Spider
had air in the system once and it caused it to overheat pretty badly.

When I worked on the SPICA adjustments, I made sure the temp was between 170
and 180 F.  But when driving, it never seems to stay at 175 F .
