Hi, I’ve recently replaced coolant temp sensor on my Deville 87, the one by the thermostat housing. And found similar one behind the alternator. But I don’t recall reading about the one behind the alternator in the service manual. So I guess there should be two or ?

One is for the intake air temperature, the other is for the coolant temperature.
