Hi

 

Looks like an air lock, try vacuum again I suggest. I had the same recently when I changed the front pipes. I assume everything was OK beforehand.

Hi

 

I don't think you need to drain and start again. You need to pull a fair old vacuum in the system to get to the air in the front. Pull the vacuum from the expansion chamber in the engine compartment sealing off the two pipes going to overflow and top up in the boot. Leave the vacuum for a few minutes and make sure it stays then let in the other 4 or 5 litres. Best of luck. Keep an eye on the level for a few kilometres afterwards and top up as necessary.

Hi

Excellent what a relief😀 it must have been an air lock. Refilling coolant system is a right pain. Keep checking level for a couple of weeks to be sure.
