I have a 98 s70, 160k miles, the past few days heat seemed to be kinda cool,( thought maybe my heater core was going bad) driving home tonight, no heat, got home car is smoking and I popped the hood and there is yellow baby poop brown sludge all over the top of my coolant overflow box... What is going on??? Did I ruin it?? It was running fine, no warning lights no weird smell no strange driving... Im scared... I'm broke and live about 100 miles away from any European mechanics... Can anyone help me diagnose this thing?? Pleaseeeee please please?

 

Check your oil level and oil color. Sounds like your head gasket let go and is allowing oil into the cooling system.
