5 quick operation and Maintenance Qs

Nothing notably different with the new fan, other than it seems to fit the radiator size better, and doesn't redirect air all over the place, just straight through the radiator.

I think I may back the jet off from a 59 to a 57. The mileage on my car dropped significantly from the 54, where I was getting 19mpg, down to 14... and it did not help cooling.

I am getting a different thought and may want to check the air gaps with a light and see if I can see a big air inlet that bypasses the radiator as you suggested Bob. I think it may be air related because on a cruise up a long steep hill the other day, the motor cranked a good 2500RPM, which is pretty close to what it does at 65 on the freeway (flat). On the hill, the temp didn't move, and I was only going about 25. The temperature stayed at 190.

Also, when I stop the car, to get a temp reading with my gun, while it's at 220 or 240 or so, by the time I pull off to the shoulder, stop, get out, and open the hood, the car cools down to 190 on the dash and head of the motor. Literally that fast.

The other thought i had was maybe the torque converter is worn, or the rear end is slipping somehow, causing the car to overwork. Is that possible? I don't know if T.C.'s go out in one failure, or can gradually wear out, but I feel like I push the gas too much to get moving. Or maybe that's just 4k lb car with 100horse motor... Not sure. It's still a issue, and it's getting gradually more stressful. I'd just like to be able to drive on the freeway... thank you for your help so far.
