Before the usual wash, I removed my wheels to clean the wheel wells and suspension components thoroughly. Was planning on full claybar/wax too, but... Well. It’s late. Next time though!
And yes, the McGuyver’d upper radiator hose worked. Fantastically actually! Engine temps are super low, and I no longer smell coolant when driving. Hooray. I’ll do the coolant reroute soon so I can replace the somewhat janky hose setup asap. I’ve got momentum, and if work things go quickly tomorrow I reaaaaally want to do the hood vents.
