1. Does it do the same on long and short routes, or only in stop n go traffic ?
2. Have you checked the AC and radiator fans, their direction, placement and speed ?
3. What is the condition of your condenser, does it pass sufficient air to the radiator ?
4. What is the status of your compressor, does it have a jammed bearing ?
