If its getting pretty cold but not quite up to the task you should look

at when this is happening. Is it on really hot days on the highway? Or is

this happening when you sit in traffic? If its going down the highway then

the system just isn't working that efficiently, you could look into adding

the Variable Orifice Valve that was a post a week or two ago. I think you

have the newer style system in your car with the accumulator. If this is

only when you sit in traffic then to improve the efficiency you can add

an electric fan in front of the radiator. This will help the system work

better under lower airflow conditions.
