but if it is clogged in the city, it is still clogged on the highway. still sounds like the heat transfer from coolant to ambient air is not taking place. are u sure the fans are working and working well? on the highway, the ONLY difference is that the speed of the car pushes a lot of air through the radiator whereas in the city, the fans have to do it. . |
Hi try to check if U have a right pressure in cooling system , does the coolant fluid go out when engine runs?
