Radiator Difference

Something is not right. I have a big stroked and bored FE, with the ERA HD fan, and pusher fans that only come on with a separate switch -- I don't use them. A few weeks ago I had the car out in almost 100 degree heat with humidity in the 80's. I noticed my puller fan came on more often than normal (I have a little discrete light that tells me the fan is on) but the engine coolant temperature stayed consistently at where it does on 75 degree days with low humidity. That temperature is between 85 and 90 degrees Celsius. Always. The coolant temperature never goes above 90 except when I shut her down and then it can creep up to maybe 93 at the most. My thermostat is the 165 degree one. My oil temperature goes to 90C on a really hot day, and I have an oil cooler which is tastefully blocked off with a removable cover. On that last drive though I had to cut the drive short after a half hour or so because I thought I was going to literally pass out from the heat and humidity. In other words, the car performs better than the driver in brutal heat. I don't know what the issue is with your car, whether it's timing, air flow across the radiator, or what, but trust me, something is not right.
