I've been told it needs to be pressure tested to diagnose the problem but just checking if anybody on here can give me some insight

Thanks all

More than likely you have gotten an air pocket trapped in the cooling system. Before doing a pressure test, I would pull a vacuum on the system to get the air out and refill the system air free.
