I'm new to this forum... my Redline Red is running hot in traffic... seems to be OK on the open road, but the temp gauge climbs up to around 235, just to the right of the last tic mark before the red in traffic. Dealer says this is normal... I've never had a vehicle do that... not even my '49 Ford F1. My concern is the long term affect on the aluminum block and heads... anyone have a fix for this?
