[Vwdiesel] Ways of cooling an AAZ

[William J Toensing]

You won't want to hear this but my guess is a blown or leaky head gasket. Pablo, what year is your VW which I presume is a Golf diesel. I am not familiar with what year & model an AAZ is. You live in Uruguay. VW & other manufacturers will make different models & have different names for various parts of the world. One thing to look for is a black oily film in the coolant expansion tank. This happened with my Nissan & Mazda diesels but not with my VW diesels. What was a Rabbit in the USA & Canada was a Golf in Europe & I think, the rest of the world. What is known as the Dasher & Quantum in the USA & Canada was, to my knowledge, always known as a Passat in Europe.
