Parts often carry over within a generation, but the manual for your exact model year is the one to trust.
What the manual does not print
The 2020 Chevrolet Silverado 1500 owner's manual does not list bulbs, battery and oil sizes; for the battery, read the label on the battery fitted to the car, then check the size against the BCI group chart; many lamps on this model are LED assemblies that are replaced as a unit by a dealer.
Buying the parts for a 2020 Silverado 1500
- Wipers: ask for a 22-inch driver blade and a 22-inch passenger blade. The manual's 550 mm is 21.7 inches exactly; blade boxes round to the 25 mm trade step. Check that the new blade's connector matches the arm on the Silverado 1500.
- Filters: the part numbers above are the maker's own brands; aftermarket boxes list cross-references to them, so quote the number (oil filter PF66) when you shop.
