The other 77 part types cover the remaining 145 parts.

This table covers the seals on each valve stem that control oil into the guides. Typical signs include a wet housing, a drip after sitting, or fluid flung off a rotating shaft. Fix the surface the seal rides on. A new seal on a grooved shaft will leak again.

This table covers the oil-control solenoids that command the cam phasers. Typical signs include a door or range that will not move, or a click with no motion. Confirm the command signal before replacing the actuator — a failed module looks the same.

Buying Engine Parts for a 2020 Chevrolet Silverado 1500

On this vehicle, the engine covers the internals and hard parts that build compression and keep oil where it belongs — gaskets, bearings, camshafts, lifters, seals and timing components.

  • Match the engine first. Every engine part here is engine-specific; each row shows which engine(s) it fits.
  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.

Frequently Asked Questions

How many engine parts fit the 2020 Chevrolet Silverado 1500?

Our catalog currently lists 171 engine parts for the 2020 Chevrolet Silverado 1500 across 80 subcategories and 29 brands, covering all 5 engine options (2.7L L4 Turbocharged, 3.0L L6 DIESEL Turbocharged, 4.3L V6, 5.3L V8 and 6.2L V8). Each part is matched to the engine(s) it fits.

Do engine parts differ between 2020 Chevrolet Silverado 1500 engines?

Yes. Every engine part on this page is engine-specific. Each row shows which engine(s) it fits — use the filter at the top to hide the rest. If you're unsure which engine you have, check the emissions label under the hood or the 8th character of your VIN.

What are the signs of engine problems on a 2020 Chevrolet Silverado 1500?

Common symptoms include oil spots under the vehicle, blue or white exhaust smoke, ticking from the valvetrain, or coolant mysteriously disappearing. If you notice any of these, identify the affected subcategory above and cross-reference the part numbers listed.

What oil viscosity is listed for the 2020 Chevrolet Silverado 1500?

Oil rows on this page include SAE 0W-20. Confirm the engine and the weight on the filler cap before you buy — high-mileage and standard fills can differ.

What should I replace at the same time?

Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2020 Chevrolet Silverado 1500 was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 2020 Chevrolet Silverado 1500?

First match the engine — each row shows which engine(s) the part fits. Then engine hard parts are unforgiving of guesswork — confirm the casting or engine code before ordering, because one model year can hide two different blocks. The notes column carries position and trim qualifiers where they apply.
