I had the same problems with excessive heat at intersections,,waiting for long signal lights when the outside temps. are above 100 degrees here in the desert. After doing everything possible, verifying temp. gauge accuracy, 180 thermostat, burping the system , strong puller fan with shroud, recovery bottle and proper coolant..everything worked much better.
I max. out at about 210 in those situations, so I experimented with the installation of a couple of "boat bilge fans" to exhaust the engine compartment heat while sitting at intersections.
I mounted them on each side of the engine, just under the fenders w' 4" flex tubing to direct the hot air out the side vents. I only use them periodically to get the heat out and they seem to pull the temp. down about 5 degrees. The biggest problem was that the fans are plastic so I had to insulate them on the inside and outside.
They sort of look like crap, but do seem to help and give me another option to control the environment.
