Thank you TXBILL. You really nailed it. I went out and checked the coolant cap. Not only was there no washer but the brass disk that sits on the washer was cracked on both sides. I then bought a new cap and took the car for a spin. I went out on the highway for about 40 min. or so to make sure it was really heated up. Then into heavy city traffic with steep hills for another 30 min. or so. No problem! The temperature guage never went higher than 85 degrees.

Thank you again, TXBILL
