Yes, that is the one. I replaced it last week, total cost a little less than $30.00 Do't forget to replace the black rubber washer.
To take out, pull the lock spring toward you and pull up the senser.

I have a 2006 vw jetta 2.0t and the fans stay on even after the ignition is off and key is out, will run until the battery is dead. I have replaced the coolant sensor and the computer sensor on the...


The fans are run by rad temperature, not engine temp on a VW.Somewhere on the rad you should see a wire harness plugged into it.That is a thermo-switch which turns the fans on and off based on coolant temp in the rad. My car is a lot older than yours but this switch is virtually hidden on the bottom driver's side of the rad. It has 3 wires going into it.There could also be another sensor attached to the engine block or head to monitor engine compartment temps after engine shut off. This will turn the fans on or off as well based on air temp in the engine compartment.

There are two coolant temp sensors. One by the oil filler tube and one near the bottom radiator hose near the radiator.
When you flushed the coolant did you replace with VW rated G12 coloant? Very Important! - You can't use over the counter coolant - it'll cause sludge in your system. You have to use G12...

How to replace a coolant temp sensor on a 2001 vw jetta 2.0


Yes it is that easy. It should be a 4 pin connector located on the transmission side of the engine head in a plastic flange. Best is to wait for the engine to be cold. Unscew the radiator cap to relieve pressure but screw it right back on. On the 2.0L engines when you unclip the coolant sensor little or not coolant loss will happen if you do this. Just unplug it, pull out the clip, pull out the sensor, and the seal which sometimes stays stuck. Install the new sensor with a new seal lubricated with some coolant, make sure it's well seated and reinstall the clip. The sensor is well seated if the clip fits right over the top, just make sure both sides clipped into position. Replug it fill the coolant with VW original coolant mixed 50-50 with water if needed and done. If you have a fault you might need a scanner to erase the check engine or fault in the cluster.

What's the reason for changing it? Eratic temperature readings?
