max, because your time is limited, measure everything you can, like head temp (all 4 cylinders if you can), block temp, header temp, coolant hose temps, radiator temp (not sure how to get to that besides through the front grills, which you'll need to remove). After you do all of that that, we'll all collectively anayze the data :-) ok, back to labor day Matthew Pollard "Racing with the wind and flirting with death Dept.
