Beck/Arnley Thermostat - 143-0849

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

All good, as intended and as described just did not need any longer as it was time for car to go.

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.

This is priced right and makes everything right when your 1.8t won’t warm up.

It fit perfectly in my 05 beetle 2.0 L. I was getting a flashing blue light so I replaced the thermostat and the sensor - it seem to solve my problem.

Replaced the thermostat on my Jetta because the temperature gauge on the dash was showing cold at all times. Turns out that the temp sensor wires has frayed and just needed to be re-soldered. Oh, well. This thermostat has nonetheless worked perfectly and gives me one less thing to worry about. Temperature is as described, perfect fit and comes with a competent gasket. I'll update if it fails but I expect it to be fine.

Hard to write a review on something you put in and forget about. Seems to work well
