Two possibilities - either it really is overheating, or the guage says it's overheating & it's not.
Check the actual heating situation first as it's likely the easiest to diagnose - a capillary guage is the best to compare with. If it's a false reading then check the voltage stabiliser first, hence other requests to you enquiring if the fuel guage is also erratic.
If it is overheating, could be the thermostat (special one in Series vehicles, and MUST be fitted like it or not else you WILL overheat it), radiator blocked, block blocked, pump not working ....
