MasterI would make sure that your cooling fan(s) work correctly and that your radiator flows properly. Are you driving with the A/C on? I ask this because there is a dedicated electric cooling fan for the A/C system when ever it is used and it should come on as soon as the A/C is engaged. If this is not working correctly your car will run hot when it isn't on the highway.

Visitor, June 27, 2010, 18:10ReplyWhen they added new coolant you need to purge the system of air.You can google the procedure like on the Peligan Parts web site. I had the same problem when the previous owner change coolant and did not purge the system. I have a 4 cylinder some ther are a little different steps. Drove me crasy at first but not overheating now air in radiator gave cooling fan a false reading and would not come on.
