I have a 2002 Nissan Pathfinder. A couple of months ago the check engine light came on and the temperature gauge quickly hit the roof. I was able to pull it into my mechanics shop before any damages was done. They looked at it and said I needed a new thermostat and housing. A few weeks later the temp gauge again went up to near the top. I live, work and shop all in a close radius so am not in my car for long periods of time but the gauge seems to measure high after about 20 minutes of driving in the city (no more than 45 mph) with the AC on. I turned off my AC and took the car back. They then replaced the fan belt and clutch that engages the fan.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
Took the car home and two days later temperature was up again. Took it back and they said they had not realized my car had a second thermostat so they changed it (at no additional charge "since they didn't catch that up front") - they kept my car for 2 days. A couple of days later the scenario replayed itself. I took it back in they changed the sensor to the temp gauge (at no additional charge) tested it and still overheated so now they have now also flushed radioator 3 times for any debris. They have had my car for three additional days now.
Please help!!! Thank you and hope to hear back from you. Andrea
