Coolant Temperature Sensor

[ericv1984]

I'm now looking into replacing my coolant temperature sensor. I've never replaced one before so I'm only guessing what needs to be done. Step one would be to drain ALL the coolant out in order to unscrew the sensor from the bottom of the reservoir tank. Step two would be to put the new sensor in then fill the tank back up with coolant. Screw the cap back on and it's done? Or is there something else that needs to be done?

Nevermind, I think I got the coolant temperature sensor and the coolant level switch confused.

I was about to say that.

You should only have to drain it to below the sensor level.
