I had someone do an EGR delete on my ALH a few years ago and have now noticed that the coolant hose that goes from the side of the head to the fire wall has a small leak. Its nothing major but if you put your hand up around where the hose connects to the firewall you will feel that its wet and has a slight leak. I add coolant to the reservoir every few weeks but want to address the issue. I have looked at it and it appears to be some type of quick disconnect at the end of that hose which connects to the firewall. How do you disconnect it? Is it easy to replace?
