I have a vacuum leak in a radiator hose which I tested and found. My problem is that the hose is under a metal bracket at the top of the radiator which does not allow me access to the hose. I am trying to remove the bracket, but where the side panels meet it it won’t budge. Is there an extra screw or something I’m missing or do I just need to pry it up? I will include pictures of the bracket and where the leak is. Please help me.
