        Nope. I can sit for about 5-7 without getting too nervous with AC fan going. Some Cali guys should chime in.

              Id put an electric fan in, Its cheap and easy and have no worries. 80 degree thermostat and I used an 82 degree fan switch to turn it on earlier. Never had a problem even idling at the track in 100 degree days.

                  works fine if you have adequate air flow to radiator.

                    Make sure the ground nuts on the back of the cluster are tight, too. If they're gone, you can get an erroneous reading from the coolant temp gauge.
