More A/C Experience

Spent to day running errands with three of my granddaughters!

We have been having days about 90 degrees, with stifling humidity.

The a/c is simply great. Keeps the car cool when idling and is fine when running. Didn't seem to remove as much humidity as modern, but taday is muggy so who knows. Point is comfortable.

The issue I see is still engine heat. My crude judgement is that the car is too hot when I get lots of low load pinging, which I got a little bit of this afternoon. My car has a 160 degree thermostat (new). Runs cool when air is off; needle comes up to 10:30 or so. With air on it goes to high noon, which is right on the edge of comfort. Any more and the pinging begins.

That means that in traffic I just turn on the electric fan, which makes a lot of noise. So far, when they ask, I tell them it's the turbine, which astounds them. FYI, my car has the Packard six blade fan plus the electric. The part in front of the radiator is huge; second biggest available from Vintage air. Probably a factor in being comfortable, but doesn't help cool the engine.

<My cooling system has been professionally cleaned and pronounced fit, FWIW.

Don't know what I might have done different that would affect this.

Naturally your thoughts are welcome, but I posted this for folks think about adding air.

If I had the money, I'd give more thought to a four row radiator....
