Who engineered that cover!! What all do I have to remove to easily get it out in one piece. Talking about the thick piece of plastic, under the air filter housing that covers the thermostat and upper rad hose connections. My overheat blow out last summer thankfully blew the hose not the the rad but getting at it with that cover seems painful.

Follow-up: Apparently you are supposed to get at it from the front, not the Air filter housing side. Remove the front covers and the left side Interstate only highway bar/rad cover, then slide out the rad and expose the thermostat and upper rad hose.  Oops. Do you really need that plastic cover to protect the coolant system from the air/fuel system? Mine might now be in assorted pieces after it got attacked by an oscillating tool. Oh and any figured out how to replace the spout of the radiator. Apparently my Rad cap had a set screw I couldn't see until I used channel locks to twist it off. I can replace the cap cheaply enough but the rim of the rad took some significant damage.

Had to read this about six times for my pea brain to understand what happened :)

Your coolant system overheated because the cap didn't release pressure and the top hose blew, then you decided to get at it from the back instead of from the side, because you have a interstate and figured that was the way, while cutting up the heat shield for access,  then you buggered the radiator neck by removing the cap with channel locks because you didn't know about the cap set screw.

Your questions are how to repair the rad and if you need the shield?

Can't help with the rad question, I'd suspect you should look to E-bay for a replacement or try a radiator repair shop.

Much debate over the years on the reason for the shield, but I believe it to direct air passing over the rad away from the rider and isolate the engine heat from the rad while sitting in traffic.

Some riders reported removing it and some of those have reported putting it back.

I will suggest you get your hands on a service manual to prevent further mistakes, but I get it, sometimes you just got to dive in.
