So temp increases when stoped or under 60kmh- get the rad cleaned, it's air flow related too through core. Do you use factory fan shrouded or elec thermo fan

after driving for a while the engine temp starts to rise. it dosent get hot enough to blow the head but it still raises. it does this when the car is stationary, but as i drive the temp goes back to normal (about half)
is this normal or is there a problem??
cheers
