Answers :

1. Possible air lock in the cooling system, does the internal fan blow hot air? You can blead the system through small bleeding points on the water hoses.

2. Head gasket gone, do the water pipes to the rad expand under pressure?

3. Faulty thermostat. Thermostat controls the amount of water directed to the rad.

4. Not enough anti freeze.

5. Rad cooling fan not starting when supposed to causing overheating. Does the tempture gauge in the dash read normal.
Let me know how it goes.
