    You'll only lose a bottle cap full of coolant. It's probably the easiest job on the car. You pull out the plastic clip on the sensor, it comes out. That's it. Stick the new one in and replace the clip.

    You lose a cup at most is a nice easy swap!

    PS get an OE sensor, bit costly I know but I have had 3 eBay ones fail within 9 months.

    Cheers

    Here's a little guide but it's easy enough to find if you know the general area! VWVortex.com - DIY: Replacing your temperature sender with the updated one (green-top)

    Thermostat is hard to get a nice pic of but if you get that little cover off by the dipstick then the metal bracket and pull the dipstick out. It's to the left behind the alternator it's a hard black pipe with two little bolts and a radiator pipe running off the housing. I couldn't really see from the pics but have a little poke about and it becomes clear!
