Gurgling noise after coolant change 1.5dci

[hardcore]

Hi

Just done a timing belt and water pump change on my megane 1.5dci , however when replacing the coolant as per manual I get a gurgling noise from around the heater matrix area , temp seems to climb as normal and the heater is blowing hot air. . But I have noticed that the top radiator hose on left is cold ? Would appreciate some advice. , done the same job on a 1.6 scenic with no problems at all . Thanks

Bleed screws do you mean ? I used the 2 , the one one where the thermostat is and the one on the bulkhead , however it is fine now , it disappeared after the test drive , everything is working normal , no noise, no overheating and have good hot air . Thanks
