During the ride home the last couple months, my aftermarket autometer temp gauge is saying 220-230 degrees on extended trips in the sun. However, when I get home, I dont see anything coming out of the radiator tube, a drop of antifreeze at most. The cap is rated at 13 pounds, and Ive never seen steam come out of it. I have a 2-row, non aluminum radiator, that doesnt seem to be the original. Im using a 50/50 mix with a bottle of water wetter thrown in. It only seems to get hot after about 15-20 minutes of stop and go traffic with the a/c on. At idle, it grows steadily, but not quickly, but after accellerating a bit, it can gain 10+ degrees and never go back down.

My question is, could my temperature gauge be reading incorrectly, or maybe the sending unit is picking up a hot spot?

Would getting a 3 row radiator help any of this if it is in fact overheating?

Is it mechanical or electrical?
The electric ones are known to send false temps...but autometer is a good brand.

electrical. Just an 18 gauge wire from the sender to the gauge.

Could be the gauge. Get yourself a mechanical for a more accurate reading. But beyond that - from one Texan to another - that 2-row isn't going to cut it! My car always ran cool on its original factory 2-row; but despite that trouble-free history, I stepped up to a 4-row when I added A/C a couple years ago. The gauge should obviously come first (to determine if you indeed have a problem). But if I were you, I'd go ahead and start setting aside a few dollars for a 4-row from Dallas Mustang. It just makes good sense in all this extreme heat we have. Also - you may want to consider a little less anti-freeze (than 50/50). Maybe a 70% water 30% anti-freeze mixture, and add a bottle of WaterWetter for good measure.

what about this one:

Should work just fine, and if you want to help it even more, get an elec fan. It frees up some HP also.

Mine was doing the same thing. I talked with a pro about it and he told me it was the weather. Sure enough, I haven't seen the problem since that 100 degree plus day.

You would be surprised at how much a 3 or 4 row will help. How about this August weather in Texas????Man, I can't believe the rain and nice cool weather.

Either youre being silly, or you live in a different Texas.

Its 98 today with 45% humidity.

Im not really sure about that 4 row from mustangs plus, it just seems weird. What 4 row would you recommend for my 67 in the $200-$300 price range.

The one from Dallas Mustang that I mentioned in my earlier response.
