Review on 🚗 TOPAZ 06D121111G - Coolant Flange & Thermostat with Housing for Audi A4 2005-2009 2.0T by Mark Ponnusamy

Thermostat housing fitted everything worked fine but the next day I noticed coolant on the floor of my garage. I checked the body again to see where the leak was coming from and found that it was leaking through the supplied o-ring. Took it off and compared it to the OEM o-ring with caliper and it turned out to be not only a little thinner in diameter but also a lot softer. Original O-ring cleaned, everything reinstalled and no more leaks. Just wanted to post this so others can compare the original and new o-ring before having to install the manifold and do the job twice.
