Hello, my Volvo V60 D3, built in 2011 with a 5-cylinder engine and 163 hp, now has 230,000 km on the speedometer and is causing problems for me. The cooling system is constantly overpressure. The cooling fluid level was initially at maximum, but after about 50 km the message appears: “Cool liquid level too low, please stop safely.” If I open the cover of the balance tank, the liquid level increases a bit, but I still have to after a few more Kil My Volvo workshop suspects that either the cylinder head gasket is defective or that there is a crack in the engine block. What do you think? Has anyone had similar experiences?
