if you try to go with aftermarket for this sensor, the odds are against you. i tried two before finally getting real and buying the oem part. the first one was twice the temp of actual. so it would show operating temp when actually cold and show overheating when actually operating temp. second aftermarket sensor showed cold right at first and then shot to just past operating temp before the engine was actually warmed up. radiator fans run right from the beginning if you even looked at the car funny. real nice when it's 30 degrees outside and you're trying to warm up to use the heater. i figured it's just a thermistor, how could they screw it up? they found a way. stick with oem...
