Coolant - Red temp. gauge light

[sentipede]

On a couple of occasions recently, shortly after start up, the red light at the end of the temperature gauge has started to blink red. When I turned the car off and restarted it, it seems to reset and go away. Is it possible that I am low on coolant? The car has about 24K miles, and was serviced 2K miles ago...no leaks.

If I just need more coolant, what kind/brand etc...and how much should I use?

Thanks in advance!

If you are adding to existing coolant I would use only Porsche coolant.

A mix of 50-50 with water should be fine. Fill the line on the coolant tank - with the engine cold.

The level sensor is very sensitive. Just a little low and the light comes on. When you restart the coolant is hot so it has expanded a bit, and the level is higher. That is why the light does not come back on after a restart.

Just add some water to bring the level up to the max.

Distilled water?

Yes, distilled water would be best.

OK,

Well, I finally got around to picking up some Porsche coolant, and just filled it up. The coolant that was already in there looked yellow. This Porsche coolant that I purchased was pink even after the 50/50 mix. I added it and the light is off, is there any reason why the original coolant was yellow?

Thanks!

Porsche changed to pink coolant recently. Green/yellow was the old color. Can be mixed, no problem. Use 50/50 coolant/water (distilled water). --Brian
