Hello guys, I have a problem with my Volvo s80 II 12.2012. Engine overheating. Water pump, thermostat, zanremen, pressure compensation lid with accessories I have again at pitstop. The problem still exists. In addition, the coolant (-30) is lost (from the container due to a wage for compensation – whether everything or not is not to invest). Top/Lower hoses are heating, but when heating comes in no warm air. Top hose has a lot of pressure. Ventilator switch et quite normal 10C/50C/90 Celsius. Diagnostic didn’t give anything. Everything was fine. A Volvo Frick (his own workshop for Volvo) told me today that probably thermostat was not installed properly or head gasket. Pitstop and in the workshop are clueless where the problem lies. Could someone help me?
