I got a 2000 Ford Taurus SE, 12 valves, 75000 miles. It overheated on highway when I was stuck in traffic jam, and the coolant reservior broke. However, it runs OK at normal speed of 60, 70 mph.

I put a new reservior and have the radiator flushed. It still overheated in traffic jam or idled for a long time. But runs OK at normal speed.

I replaced the thermostat and the coolant temperature sensor myself. The problem is still the same. So, I suspect it is caused by the cooling fan. But the fan at least run once after this problem appeared.

Is it poosible the control problem of the fan? Where sould I start to test the cooling fan system?

Thanks.

I have a 2000 Ford Taurus and it is doing the same exact thing; I have had the serpentine belt replaced, reservoire tank, and thermostat and it is still running hot however my fan runs normal. So if you figure this problem out please inform me and I will continue to look for a solution as well. Thanks a lot.

I would check the front of the radiator for debris. It could also be a bad water pump impeller.
