OK. So I'm getting scary temps(over 100) again when going uphill on hot days(90+). I've heard of these cars running cooler for people and want to know if I'm missing anything.

So far I've replaced:
Thermostat
Expansion tank
Radiator
Fan Blade-switched to plastic
Water Pump

Done a citrus flush
Drove around the neighborhood with exhaust pipe off(still creeped over 85)
Pressure tested system(good)

The aux fan comes when it's supposed to(up to 45mph) so that actaully works well and cools the temp down. But at 50+ uphill the temp just keeps rising gradually

The car just seems to have a tough time regulating itself under load

At idle, in traffic at 100*F ambient temperatures, the coolant temps don't get quite as bad(only around 90) as under load.

The problem doesn't seem to have gotten worse after 7000 miles.

Any other ideas? Blockage in the cooling system somewhere?

Thanks.

The problem is the driver. He gets scared. The engine couldn't care less if it runs at 90C. or 110C., provided that the vehicle has proper coolant and a 140 cap.

The cooling system on these vehicles is insufficient to remove the heat generated under high loads and high ambients without a typical rise in coolant temperatures.

Many folks complain about 110C. coolant temperatures under these conditions, however, none of them (with properly maintained and repaired systems) have ever suffered an overheat.
