Chrysler Cordoba 1977 with 400 CID, Overheats
400 CID with standard replacement radiator. Overheats under load (sustained speeds in excess of 70 mph in hot weather or when traveling under load (mountains with 6+ degree incline for 4+ miles) Not equiped for trailer pull, but I had no problem with a 78 model with dealer installed trailor options (cooling, breaks, suspension). Engine recently rebuilt but problem persists.
