The coolant warning light came on Saturday so checked and found that it had almost disappeared, couldnt see any leaks so was abit confused as to where it had all gone. I topped up and now had the same problem this morning. Cant see it leaking anywhere but noticed 2 or drops drops of brown liquid near the front of the car, looks like dirty coolant. No Mayo under the oil cap and the temperatures were almost 0 this morning so the white smoke is more than likely just condensation. The water pump was replaced 5K miles ago and theres no problem with the car overheating. The temp guage on the climate control reads between 88 and 93. Any ideas on whats going on?
