Problem car overheating. First mechanic came around, stripped car on driveway and left it in pieces, never returned. Second mechanic - again on the driveway replaces radiator, condenser, fan motor, car still overheating. Says head gasket has gone, takes car to garage replaces engine, car still overheating. He says it’s Ok. but overheating with a whine. Eventually I take car to a reputable garage All it needed was a simple thermostat. This company has cost me nearly three thousand pounds with their in vetted mechanics and my car had never run the same since they became involved.
