Blinking temperature light - Page 2 - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Change the water pump (every 3 years if possible). The impellers in the porsche design are known (99% probability) to break or erode. That's what I've learn on 986forum anyway. Results are very low water circulation and overheating.

Keep on the look-up for impeller debris in the thermostat area. And no, i am not joking. Ask porsche if you don't believe me... heard they gave away many FREE water pumps to nasty and pissed customers

I am surprised to see that even a 7 years old thread can still be indexed. Well spotted mate

You may have air in the system. does the heater blow hot air? open the bleeder valve. after the car cools, see if the level goes down. if not, pump is out. pull it and see.

The coolant light will also flash if your intake fan malfunctions.

I have a '07 that the gauge would "stick" on the far left and the light would blink when the car was driven a few blocks. As soon as the needle moved the blinking would stop. The scenerio eventually turned into the warning lignt telling me to take the car to the shop. So, I called the dealership. My car is a CPO car and Porsche picked the car up, and sent it back to me the same day telling me it was a little low on coolant. I thought the problem was fixed...Wrong. The car started doing the same thinf a day or two later. Porsche came again. This time they checked the thermostat and some temp sensors and replaced one of the sensors. (sorry, I dont have the service tag in front of me). Been driving the car for a week and no warning lights at this time.
I'm happy I bought a CPO Car!!!

Thanks

normal is relative. if it's hot outside, the engine will run a little hotter.

normally mine sits on the left side of the "8" in "180" however yesterday being so hot (middle of nowhere kansas) and driving down the highway at *ahem* slightly over the speed limit, it stuck straight up and down.
