GMC shares its platforms with Chevrolet — Sierra with Silverado, Yukon with Tahoe, Terrain with Equinox — but Denali and AT4 trims add their own brakes, suspension, lighting and trim. Many of the GMC parts we quote are for 1999–2013 Sierra, Yukon and Envoy trucks still working every day, so we read the RPO codes off your VIN and match the part to the truck as it was built.
What’s different about GMC cooling and AC parts
- Sierra and Yukon radiators vary by tow package and transmission cooler lines — the Max Trailering package uses a larger radiator and auxiliary cooler — and Duramax trucks use their own radiator, intercooler and cooling stack.
- Water pumps on the 1999–2013 LS-family V8s are a quick job, but the Gen V engines (2014+) use a different pump and thermostat housing; 2007–2014 trucks are known for cracked radiator tanks and leaking heater-hose quick-connects.
- AC compressor and condenser orders on Yukon XL and Acadia often involve the rear AC unit; 2018+ trucks use R-1234yf refrigerant, while earlier trucks use R-134a.
