My guess will be matrix blocked. I had this when i first brought my 306 i fitted a new matrix new coolant and all was fine took me about half a day as i had never done one before.The only thing to be carfull of is dont force the matrix pipes out of the connectors enginge/bulkhead area as these break very easily. Theres a little clip in between the two pipe fittings which i didnt notice myself and cracked mine resulted in a trip to the scrap yard.
