Re: Sweet sweet smell
I think you are on the right track with the coolant and a leak. Sounds like its only present after you drive it and the whole system is up to temp and pressure. Had that happen before on another vehicle and it ultimately was the head gasket.
With that said, you mentioned one change that caught my attention which is the Killerglass radiator hose. I'd really give that a closer look. Suspecting a pinhole leak that only occurs when the system is hot and under pressure. What type of hose clamps did you use? Factory or "worm gear" style? If it were me, I'd change the radiator hose back to stock then give it the sniff test for a couple of days.
