What is normal operating temperature? My 00 S runs at 215

Usually temp sits at the end of 8 beginning of 0 in 180. In traffic it gets to the end of 0, that's when the fans start and it goes back to the beginning of 0.

If I have AC on and driving in traffic it's always sits at the end of 0

Is it high? what temperature is the mark after 180?

Thanks

I bought this: http://www.scangauge.com/
It will show real time read outs of all sorts of things.
It was informative because it showed that my "cold air" intake was hotter than stock, and that the engine temp was really high.
Also it help me prove to myself that the low temp thermostat and redline water wetter worked in lowering my water temp by 20 degrees.

Hey
Does scangauge also read out oil temp?

Thanks

No it does not. At least not directly. From my understanding the water temp is close to oil temp because of the design of the coolent system. I don't even know if the computer has a oil temp sensor.

The scan gauge is neat because it also does MPH, gallons of gas in tank, miles to empty, voltage, and many other values that I have no idea the significance of.

Fun toy.

Does the scan guage read out realtime camshaft timing? Big variations in camshaft timing relative to each other are an early warning of a pending IMS failure, from what I've read.

I did the read out on both of my Boxs. The gauge in the 98 Base is just 1 degree off and the 00 S is 2 degrees off of the realtime reading. I'm OK with that.

Thanks for the link!

I did the test yesterday and my gauge seems very accurate.
When cruising at highway speeds (2200-2500RPM) Temp is around 90C
When entering traffic (3k-3500RPM) I usually keep it in higher RPM in city driving, temp rises to 95C
When sitting in stop and go temp rises to 102C, fans come on, temp drops to 96-98C, fans turn off, temp rises again.. and so on
Highest I saw was 105C with AC on, sitting in traffic

Does that sound high?

I also did the test for waterpump/fans in my driveway, I let the car sit with engine running. Same results, fans come on at 102C and temp lowers to 97C and fans turn off and so on

Thanks

The Boxster has a reputation for bad water pumps. Sometimes the impeller blades break up and of course water flow is reduced if some of the blades are missing. I've seen recommendations that Boxster owners should think about replacing their water pumps every two years. Personally i suspect that could be your problem. Even if the fans are functioning correctly, if the water isn't flowing you're going to overheat. I think you need to rule out the water pump before going crazy on fan issues, etc.

The fans have two speeds. They are very loud and forceful in high speed. You might need weather up toward 90 with the AC on before the fans will shift to the higher speed.

On my 2000 S the temp needle never gets past the "0" in 180 no matter what the conditions (slightly beyond straight up). I was idling for about 5 minutes yesterday in 99 deg temps while parked and that's all the higher it went with the AC going full blast the whole time. It sounded like a hovercraft between the radiator fans and the engine compartment fan.
