    Volvo 160d coolant bottle pressure

    Has anybody ever experienced the coolant bottle on top of the motors in 2013 Volvo 160d over pressurizing? I’ve been told these machines have a known injector cup issue and that could cause this. No codes present. Machine runs strong with no startup issues.
