My daughter has a 97 3.0 CL. She has been having an overheating issue. We have replaced the water pump, radiator and thermostat. It still overheats when in traffic or sitting in driveups. Had a red dye test done...showed nothing they said. We have had the car running in the driveway until it gets up to normal operating temp and the fans do come on and the needle never goes past normal. We were having this issue with the original engine in the car so we put a used engine in and its like the problem never went away, even with all the new parts. At my wits end with the car. Help....is there something else that we might be missing. Thanks.
