The wire mesh were supposed to be designed for car radiators but I examined them last week and figured out that they slowed the airflow by maybe 50% (test with a hair dryer). That would mean that even at normal speed not enough air would flow through the radiators.
So I got rid of them, and alas the coolant temp no longer stared spiking.
Success?
Not really: Today on a normal drive in 70F weather, the oil temp went to 230F and the oil pressure dropped very low when idling (which confirms that the oil thermometer was reading correctly).
So it seems that I no longer have an issue with coolant getting too hot but the oil temp is still going out of control
So next step, replace the oil cooler?
(It's an "S" so I already have the larger oil cooler)

I'm not sure you have a problem, 230 is about 106-108C, which in stop and go traffic, is probably ok. Oil temp is usually 5-10C higher than water temp. When you say oil pressure is very low, how low is it?
