check engine light, P0125

Hi,

I'm new to this forum and it looks like there are folks out here with a lot more knowledge about cars than I do :). Hope you can help me!

I have 2001 ZX2 with 50000 miles and I've always been very happy with my car, never had trouble before until 6 weeks ago my check engine light came on for the first time. I went to the FORD dealership right away and they told me that the engine coolant level was low. They refilled it and the light went out. I had the feeling that my car was running smoother afterwards (the car has always had a rough idle, but it was shaking less now). Unfortunately last weekend it came back on after about 1000 miles. Half a liter of engine coolant was gone again. The dealership checked again for a leak but couldn't find anything.

The problem is also that I shipped my car 5 years ago from the US to Europe and no one has experience with this car here. So your help is very much appreciated!

Try letting the car run at idle fully warmed up, heater on, to see if the leak only leaks when the system is under pressure.

Thanks for the response! It seems I forgot to mention the fix after the problem got solved. Sorry about that. It was the thermostat causing overheating. Since it was replaced in October I have not had any problems with it.
