2001 Porsche 911 water cooled
I have just moved to Scottsdale, AZ (temps at 110) - I am accustomed to driving the 911 Porsche in Northern, CA. The thermostat is running at 225 degrees vs a usual 180, and the air-conditioning stops pushing cool air. I have just replaced the water reservoir (had a leak) and it is still running hot.
New thermostat with a different setting??
Clean the radiator of built up debris??
Add any additional cooling mechanisms??
Any thoughts
