How To - 4th Gen Cummins Heater Core Flush

Thanks for the post my upper house does not have a hose clamp and for the life of me I cannot remove the quick disconnect. Any suggestions?

We were thinking maybe cutting a quick disconnect tool shorter to fit in the area. I’ve seen most people disconnect it but I also had a very hard time trying to get it off.
