I want to change the thermostat in my 2001 Audi A3 8L1 1.9L myself, but I don't know which one to buy. I went on my local dealer's website, punched in my vehicle information, and I got a few thermostat results from different manufacturers. They all have the same temperature info, but vary in size.

Since I don't have any technical specs for my car or anything like that, how would I go about choosing the right one?

Go to a site for parts diagrams with a VIN/chassis number lookup like http://www.realoem.me. Give it a try, I think it will be quite helpful.

Using that site based on an ASV engine I believe you need 044121113

@FCPEuro neat website

What I always look for is:

  • is it in the correct temp range for your car
  • is it a high flow thermostat?

you need the proper temperature so the engine will run correctly without getting too hot or cold.

A high flow thermostat can relieve some problems with extra hot days.
