This is kind of out of left field, BWTF. Try replacing your ECT sensor. It's a fairly simple resistance vs temp device, but if it's sending the wrong signal to the PCM, it could effect fan turn on just enough. The suggestion about putting in an "independent" thermo device wired to the fan relays could be telling, as well as a manual fan switch. None of this will cure an overloaded cooling system, but like you seem to think, I agree the stock cooling system should handle what you're running. -and I (with stock engine only!) have been caught on I-75 for hours behind a wreck and monitored w/Autotap and never saw excessive water temps, with AC running on MAX.
And another thought...even a scanner like Autotap or whatever is only going to see the temp that the ECT sensor says.......

How is it done and where is it?
But...the fans are kicking ***, running on HIGH, every time i pull over and stick my hand down there to check them when its hot.
Thanks.

Also, where is the condensor and how big is it?
When I look up under the front end at the radiator I don't see anything but radiator.
My tranny cooler is on the passengers side in front of the radiator.

The over heating only happens when I drive in the city.

So, after pulling my heads off because I thought I had a blown head gasket, I think maybe I found out why I'm overheating. Could this be the reason?
My pistons, all 8 of them were caked up bigtime with burnt oil. I'm talking it was so thick that some of my valve eyelets on the pistons were almsot all the way filled in. I was told that this stuff will get hot and have red hot spots all over the surface and cause pre-ignition. Now, once this pre-ignition starts happening because the A/C was turned on and raised the temp a little bit (normal), will it kind of snowball out of control from there because of the pre-ignition and keep getting hotter and hotter?
Hoping that's my overheating problem.
