Overheating

Engine Coolant Temperature Sensor, Mounts in the cooling system in the engine cooling passage ways, most times its in the intake, or side of the block some have both or two sensors, check a manual for where yours is, or install a after-market kit like a Adjustable Cycling Temperature Switch.

I fixed that. Fan works now. But car is still over heating. Whay else could it be?

What about the thermostat, or air in system needs bleed out? Hose's collapsed? Cat clogged up? Do a compression test on cylinders to see if head gaskets have failed and a exhaust in cooling system test.
