I've never vacuum filled any of my vehicles when I just do a drain and refill. I just drain the radiator, refill it and then check the level after the first few drives.
I've always just done drain and refills every 30,000 miles on my Edges. My 2011 just hit 200,000 on the original water pump and my 2022 just had its first drain and refill. I also just did drain and refills on the PTU, RDU and trans.
I don't think any automobile manufactures undercoat and rustproof their vehicles. I wish I had the time to get carried away like they did in that video but I've done pretty good with cans of rubberized under-coating, Transtar Amber rustproofing and a few cans of Surface Shield every fall. I live in a nasty rust-belt and my 2011 Edge was still in amazing shape when I sold it a few months ago.
Had to change this response. Only use a stress ball. The Hulk was too small and didn't fit tight enough so it got rolled up in the shade and was a bear to get out.
I just jammed it between the bar and the roof right in the middle. The clip trick that everyone uses just adds pressure to the bar on the passenger side which can also prevent the rattle but mine kept coming back. Putting more pressure in the middle of the bar seems like a better solution and the foam keeps the pressure on the bar despite temperature changes.
So my felt pad under the clip only works for so long but the rattle eventually comes back. I finally came up with a permanent solution!!! The black cross bar that the sunshade rolls under was always the main suspect in my mind. Just for the heck of it I jammed a microfiber towel between that bar and the roof and the ticking/rattle never came back. A foam stress ball works even better and allows the sunshade to operate just fine.
