Review on Astro 78585 Universal Radiator Pressure by Michael Wilder

So I asked if this would work on a 2007 Chevy Avalanche. I received two replies that yes it will. This information was wrong. I spent $200 on this kit not having what I need. If you have a mid or late 2000s GM you will need to order cap 7858541. I will not be returning this kit but I am disappointed that for the price it does not include a cap. The seller needs to scan the manual into the photo gallery here so people can see which caps fit which cars. Uppercase letters ending in -03 through -19 are included. Full numbers 785841, 7858542 and 78585230 are not included in the package and will be paid extra. Another $16 to get the right cap.
