radiator cooling fan turn on temperature

Is it possible for the dealer to change the cooling fan on/off temperature settings?

Not easily, the fan control (on and off) if done by the DME software; to alter the temperatures, you would have to install an external control system of some sort, which a seriously doubt a dealer will do. Why do you want to alter the profile?

I'm a strong believer that too much heat kills. I've seen engines with lower temp thermostats live for literally hundreds of thousands of miles. I guess I can tie an external toggle switch to the existing fans or add my own fan to one of the radiators to provide more cooling when tooling through the mountain roads.

You could also clean out the collected debris in your radiators (always a problem on these cars), and install a 160F thermostat (always an excellent idea).

I did install the 160 deg thermostat and in cold weather or at highway speeds the engine tops out at 180 instead of 210. That works great. Its when I'm going slow in town or up the mountain passes that it will jump right up to the 210 zone where the cooling fans kick on. But, over 95% of my commute is highway so it runs right at 180. I have checked the front side of the radiators but have not had the nerve to take the front bumper skin off yet to do a deep cleaning. Is there a posting on here or pelican or somewhere that I can follow that is clear as to how to disassemble the front bumper to get to the radiators? I have a strong suspicion its relatively clean in there but don't know that for fact since i haven't been in there.

There are several DIY's for this, this is a pretty good one: http://www.skylersrants.com/Porsche/Radiator/Radiator.html

In addition to the 160 stat, you might consider the larger oil cooler and a third radiator if you car does not already have them.
