Boxster yellow cooling light flashing?


Recommended Posts

I have a 1999 Boxster. On the temp gauge there is a yellow lights that alarms you if your car is overheating or if it's too cold to run. I first had this light go on because my engine was very cold and i tried driving it. Now months have gone by and even if it's hot out this light still goes on. Any one have any clue as to why this still occurs. If i let the car heat up and run for a little bit, then turn it off and restart it the light will go away. BUT then if i'm on the highway and the temp drops the slightist bit the light will flash again. Any clues?

I'm bringing it to the dealer this mornign so any help would be great before i bring it in

Could be low, but I bet it is the reservoir. Common problem.

Do you mean the coolant could be low, or the actual reservoir could be damaged?

Look for leaks in the rear trunk (lift the carpet) and near the left right rear wheel. Also, check around the (blue) cap for leaks. If your cap part number does not end in "01" it should be replaced.

If you don't have any leaks then it is likely a bad level sensor.
