Prado 120 Colorodo engine (2002) has a strange heating problem. When ideling it does not go beyond the half way but when driving at speeds of 110 kph or more the guage rises to 3/4. No leaks! New fan coupling fitted and thermostat?
have the same problem?

Flush the radiator, engine block, and heater core. There could be a restriction in any of them.
