I have just carried out a coolant change on my 2016 Kadjar 1.2 tce and followed the service instructions (dialogys) fully.
upon refilling opened the small bleed screw until good flow, then replaced cap on expansion bottle and i run engine till it reached operating temp.
I let it cool down then checked level and topped up as the level dropped.
now the cabin heater will not get warm which suggests an air lock?.(was working fine until I changed the coolant)
have anyone experienced this and how did you get the heater air lock removed
update its all working fine now, I drove the car for about 20 miles let it cool down then topped up the coolant as it was low so the air lock cleared itself, checked the level after a few days and it is normal so job done.
