Beck/Arnley Beck Arnley 143-0849 Thermostat

Installed it and works fine

Works good on 2013 vw Jetta s 2.0l n/a

part of timing job parts i needed to do on my VW passat 1.8T, exact fitment. works well so far.

Perfect fit for 2008 Audi TT 1.8l. Fit and finish were good. Gasket was high quality and fit perfectly. I did check the thermostat in hot water before installing (I've had new ones fail before). It started to open (that I could see) at the appropriate rating, so that's perfect. Came in typical thin paperboard box, but that's standard.

It seems to work, resolved my issues with excessive cooling during the summer. Does not keep the engine warm during the winter. In all fairness, it is a very small displacement 2.0 and perhaps the orientation of the temperature sensor contributes to the low temp reading, perhaps. That being said the car still runs cold over the cooler winter days, it is my suspicion this is the result of the thermostat not sealing completely or opening prematurely. It does work, although maybe not as well as a higher quality part.
