My rexton presents overheating (the temperature needle is abruptly uploaded to H) only on the road after 90 kph. In the city, as this speed is reached, the vehicle remains well as a tranco. Remove the thermostat, change the two temperature sensors, we check the electrical system, we loaded viscous, the radiator was cleaned, the water changed by refrigerant liquid ..... and nothing ..
the check Engine remains turned on and the Scaner says that it is the problem of the preheating spark plugs ...
any suggestion?
