Chevrolet Silverado 1500 2007-2013: The Parts That Actually Wear Out

The Silverado 1500 GMT900 ran from 2007-2013 and is the last of the pushrod-simple full-size Chevys. After enough of these come across the parts counter you start to see the same short list of components over and over. Here is what owners of this generation actually end up buying, and what to know before you order.

Heating and Air Conditioning

The usual tell is a clicking or ticking behind the dash when you change temperature. Heat is the accelerant on this one, which is why it shows up faster here than up north.

Common parts in this group: cabin air filters, blower motors, blower motor resistors, A/C compressors, condensers.

Worth knowing: Condenser and evaporator core dimensions are specific, and a near-fit leaks at the seal.

Ignition and Engine Management

The usual tell is fuel economy that drifts down a mile or two per gallon over a few months. Mileage is a rough guide here. Load, heat and road surface matter more.

Common parts in this group: spark plugs, ignition coils, camshaft position sensors, crankshaft position sensors, oxygen sensors.

Worth knowing: Plug gap, heat range and electrode material are specified per engine, and GM’s Active Fuel Management and Dynamic Fuel Management engines are sensitive to it.

Body and Exterior

The usual tell is a window that drops into the door or moves crookedly. Heat is the accelerant on this one, which is why it shows up faster here than up north.

Common parts in this group: mirrors, door handles, grilles, bumper covers, headlamps.

Worth knowing: Factory paint codes only work if the substrate and primer are the same.

Exhaust and Emissions

The usual tell is an exhaust tick on cold start that quiets as the manifold expands. Worth checking at the same time you rotate tires, since the wheel is already off.

Common parts in this group: catalytic converters, oxygen sensors, DEF injectors, diesel particulate filters, EVAP purge valves.

Worth knowing: EVAP components are leak-rate sensitive, and the monitor is comparing against a factory reference.

Filters and Fluids

The usual tell is an oil life monitor that reaches zero faster than it used to. Mileage is a rough guide here. Load, heat and road surface matter more.

Common parts in this group: oil filters, air filters, cabin air filters, fuel filters, transmission filters.

Worth knowing: GM oil filters are built to a specific bypass pressure and anti-drainback valve spec, which matters most on cold starts.

Cooling System

The usual tell is the sweet smell of coolant after shutdown with no visible puddle. Worth checking at the same time you rotate tires, since the wheel is already off.

Common parts in this group: radiators, water pumps, thermostats, coolant hoses, cooling fans.

Worth knowing: GM cooling systems are DEX-COOL based and the seal and gasket materials are chosen for that chemistry.

Before You Order

Have the VIN ready. On a Silverado 1500 the same model year can carry two or three different engines and several suspension packages.
Check the SPID label in the glove box or console for your RPO codes.
Front and rear parts are rarely the same number, even when they look identical.
If the part is electrical, confirm the fit before you order. Electrical parts are not returnable at any GM dealer, including us.

If you are not sure which version fits your build, send us the VIN and we will confirm before anything ships. Shop our Chevrolet OEM parts catalog or search for Silverado 1500 parts.
