I'm not a mechanic but I play one on FR.
Something you might consider when in stop and go traffic to prevent overheating, is to pop your hood to the safety latch (make sure it's a good latch). Typically, the way engine compartments have been designed over the past 25 years, engines actually heat up before they cool down for the first few minutes after shut down. Most of those hood safety latches are designed to hold for highway speeds in case you forget to put it back down.
Years ago I was hauling my HD in the back of a small old PU truck through the hills of WV. I kept it from overheating by popping the hood and turning the heater on.
A police car, heading to the accident scene asked if I had trouble (which was great of the NYPD), and I said no.
Sometimes on a very nice day, time to get out of the traffic (especially if there is grid lock) and enjoy the view! My car will run very hot in standstill traffic after about 20 minutes...
But I have no knowledge of aircraft engines... Not a clue...
