   Are your coolant levels correct
   
   Also do a compression test to check the Head Gasket.
   
   Look for any oil in the water / Mayo in the oil (bear in mind that there can be some of the latter due to short journeys). These are signs of the HG
   
   Also the rad might not be functioning right. Using your hand make sure the radiator hasn't got any cold spots that would indicate a blockage. If you have I would reverse flush the coolant and get some fresh mixture in. Make sure its bled correctly though.
   
   That should do for now
