Coolant Temperature sensor location

[subjfd]

I know...dumb question....

But I cant find it, and my milleage is baaaad, and I have a code 21...So I got a new one from the dealer.

2 questions:

1) Where is it lovated (idiot proof)
2) Is it necessary to remove coolant, or a quick swap will do it.


In my vw, it says to remove the coolant, but I can manage with a quick swap ! And I know....Not to forget to apply teflon to thread !

Cheers

1) It's threaded into the water manifold that runs under the intake manifold. Look under the rear passenger-side intake runner for a sensor with a reddish-brown 2-pin connector. Next to it is the probe for the temperature gauge; this one has a single-terminal connector on it.

This is a picture of both parts:

I believe a deep 19mm (or maybe 17mm) socket is what you need to get the sensor out. There's also a copper washer between the sensor and the manifold that provides a seal; be sure to get the old one off.

2) You don't need to drain the system. Some coolant will spill out, and a little bit of air will get in, but it'll clean up and burp out relatively easily.

3) Do not apply Teflon tape or any other sealant to the threads. Just use a new annealed copper washer. A new sensor will come with a new washer.
