03 C4S air in coolant ?


Recommended Posts

Hi Guys

my C4S coolant temp light was flashing,temp didnt go up,i picked up the pink porsche coolant and with 50/50 distilled water i topped it off,took a little over a quart,surprised it was that low,dont see any leaks or signs of intermix,can coolant level go down over time?,how can you know if there is air in there,i have read that it is hard to bleed these

Thanks in advance

Albert

If there was no job done on the cooling system, no air can come in. A small water leak is still possible, radiators, water pump, piping, etc. even a bad cap may cause this problem. The cooling system can be checked out for leaks with a test device, which puts pressure on the water circuit.

when you added coolant did the light go off? were any fault codes showing up on the computer? I wonder if there is some type of coolant level sensor that read the low coolant level, like sensors in windshield washer tanks? good luck...

Have your water pump checked. Your car is about the right age for the pump to fail. These engines do not like to overheat. I had a warning light and a low coolant level like you describe in my 2000 996. I topped it off and kept driving it. A few days later it blew up (oil/water intermix). huh.gif Water pump had failed with no warning and caused massive overheating. It either cracked a head or the freeze plug blew.

Not trying to scare you but have it checked before you keep driving the car.. Better to err on the side of caution when that light goes off.. Your coolant is going somewhere.......rolleyes.gif

Good luck!
