Engine Cooling problem
2000 Mercury Sable 6 cyl Front Wheel Drive Automatic 170000 miles
A couple months ago I had a problem of the engine temp rising when I would sit at an intersection. The coolant in my resevoir tank was rust colored and needed to be replaced, so I had it flushed and replaced. That fixed the problem for the time being, then it started up again. I noticed that my coolant had been leaking from the resevoir tank, so I replaced that yesterday and refilled it with new prediluted coolant. I drove it around for about 20 minutes to test it, and it worked fine until I got on the highway, and then it started to heat up again. When I got off the highway the heat stayed up, so I parked it at home. After my car running for fifteen minutes the brand new coolant I had replaced was rust colored again. Any ideas as to what the problem might be? Could it be the thermostat? Should I try getting the coolant flushed again before I do anything major?
have the same problem?
