At startup get this error message: fault cooling system error visit repair shop.
car cooling temperature reads 194 when warmed up. It is not overheating and runs good. warning clears with info lever and warning only comes up when starting car.
A simple thing is to check that your coolant cap is not cross threaded and that it is tightened enough. If it is secure and the problem persists I would do exactly as the message says . . .
