Not really "today", more like "over the past 3 weeks in my garage", but...
Replaced all coolant hoses (radiator / heater)
Both upper and lower radiator hoses had started to squeeze out coolant where the hose connects to the engine, and after pulling off the hoses the rubber had half disintegrated into a gooey mess. Also took the opportunity to replace the infamous plastic heater hose coupler on the rear passenger side with a metal unit from Autotecnic. Ultimately replaced every rubber coolant hose (including heater hoses and tiny driver side coolant pipe hose) just to be safe.
(Also, vacuum fill tools are amazing for refilling the coolant system. OEMTools 24444 for the win.)
Replaced left/right motor mounts and rear transmission mount
Was fighting some really bad drivetrain vibration when stopped but in gear. Decided to fire the parts cannon and swap all three mounts. The left/right engine mounts were probably fine, the old ones didn't look much worse than the new ones. But the rear transmission mount had basically collapsed by about 1" vs the new one. No torn rubber, just sitting 1" lower. It completely fixed the vibration I was having.
Replaced serpentine belt, tensioner, and all idler pulleys
Old belt was looking pretty rough and was time to change. Tensioner was still showing within spec, but when I pulled the belt and spun the all the idler and tensioner pulleys, every single one had noisy/grinding bearings. They were also all rusty and trashed from years of road salt. As a bonus, the engine bay is a bit quieter at idle now without all those noisy bearings.
Replaced front hood latch cable and removed/cleaned hood latch mechanisms
The hood latch cable is two parts on Gs and Ms, and it has a problem where the front half of the cabling mechanism will stretch. Symptoms are that you pull the hood release and the hood doesn't pop. Replacing the hood latch cable fixed it, and while I was in there I cleaned up and regreased the latch mechanisms and the secondary hood safety latch.
