How the 2018 compares with nearby years
Against the 2017 Sierra 1500: The wiper blade lengths, oil filter and cabin air filter are the same in both manuals.
Against the 2019 Sierra 1500: the oil filter and cabin air filter changed (PF66+PF63E in 2019 vs PF63E+PF48E in 2018; CF185 in 2019 vs CF188 in 2018). The wiper blade lengths is the same in both manuals.
The 2018 Sierra 1500 belongs to the 4th gen (K2XX), which began with the 2014 model year (MY2016 refresh: new grille/headlights/fascia; LED headlights and taillights on SLT/Denali; 2019 'Sierra Limited' carryover); generation dates. 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 2018 GMC Sierra 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 2018 Sierra 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 Sierra 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 PF63E) when you shop.
