Owner had just purchased the vehicle and it overheated on way home.

Owner just purchased this vehicle in a private sale.
It overheated about 9 Km into the trip home and stopped at a service centre. There replaced the thermostat and sent the vehicle on its way. Seven Km on it overheated again and was towed to us.

Owner was asked about the traffic conditions in which the car was driven. First time it was low traffic and high speed and second in evening medium traffic.
