Default Water Temp. Sensor

So I guess now that my brakes are fixed I'm looking at replacing the water temperature sensor. Before I do anything 1)Where is it? There is a big hose going from the radiator to the engine, and a small wire and what looks like a sensor below it, is that it?

and 2) Do i have to drain the coolant to get at this thing?

On a non turbo car...it's on the coolant overflow tank. Pull the tank up from it's holder and you'll see it on the bottom. I imagine you'll lose some fluid that's in the overflow tank, but not much.

Are you looking for the coolant level sensor or the actual coolant temperature sensor?

For the non-turbo:

The level sensor is under the reservoir.

The temperature sensor is where you said it was. Under the large hose on the engine. That's also where the thermostat is located.

I imagine it's the same for the turbo motor.

My remedy : two gallons of ice cream. Just wash out the buckets when you're done and you're good to go. Draining and refill is easy like sunday morning that way.
I suspect you only need to get enough out to get the upper radiator hose empty.
