General Luke warm heating

[Will I like it? - Yep!]

I have a diesel Grenadier that takes forever for the heating to warm up. At its last service it had the same problem and the dealer sorted the issue.
Anyone know the procedure to resolve what may be an air lock?

Thanks for your help!

All you need to do is fill up the coolant. Both the blue and black lid with HT12 coolant, level to max on a cold engine. Some of the air has purged out and levels have dropped. It will continue doing this for the first few years until all the air has gone. It will work, not perfect but it gets hot in 5 mins from cold start in auto. No condensation or fogging.

Exactly my experience, takes time to get all the air out if not done during manufactur
