Am I worrying needlessly about engine temp?

I've done this too. My car sits on the rightmost edge of the 0 in 180 in hot weather in heavy traffic, but will go down if I turn on the AC.

The low temp thermostat is a good idea IMO (haven't done it yet myself), but I suspect it won't help lower your coolant temps - just delay the system's reaching max temperature. I actually noticed my temperatures go down a bit after cleaning my radiators. 3rd radiator is probably the best permanent fix, if you think it's a problem to begin with.

Geez, dont know why it hadn’t dawned on me early. Just turn on the AC. And as many pointed out here, the low temp thermostat doesn’t really add to the cooling capacity. Just begins the process a little earlier. Am thinking now that the S oil cooler is the first order of business. That should add cooling and not as expensive as the 3rd radiator.
