Audi S4 - head gasket problem?
Hello.......I recently had the timing belt and water pump changed on my 2001 Audi S4 avant. Upon getting it back from the mechanic, I noticed a constant coolant leak that had never been there before. I brought it back to the mechanic and was told that it probably was just over filled when they put it all back together. Basically told me that it would probably stop leaking after a few days. Well it continued to leak small amounts for another 2-3 weeks and eventually the coolant warning light came on. I topped off the coolant and drove it home only to have it smoke like crazy and coolant was sprayed all over the engine compartment.
I called the mechanic and brought it back in again assuming that we just had a loose hose or small leak, etc. Later that day he called and told me that it was bad and looked like I had oil mixing in with the coolant and that the head gasket was probably bad..........and that it would cost a ton to fix.
Obviously, my first question was it must have been something they did as my car did not leak a drop of fluids prior to bringing it in for the timing belt work.
Since I really dont understand all this stuff, I need someone with mechanical knowledge to help me understand what happened to my car and if it could have been something that they did wrong during the service work. I find it hard to believe that it would be a coincidence that I start having problems after this major service. Thanks,
