2014 Chevrolet Silverado 1500 Serpentine Belt Routing & Part Numbers

Quick Answer

For most 2014 Chevrolet Silverado 1500 models (equipped with the 4.3L V6, 5.3L V8, or 6.2L V8 engines), here are the key serpentine belt details:

• Belt Length: Approximately 2240mm (88 inches)
• Rib Count: 6-rib
• OEM Belt PN: AC Delco 6K888
• Aftermarket Cross-references:
  • Gates K060888
  • Dayco 5060888
  • Continental Elite 4060888
• Auto-Tensioner PN: AC Delco 38194 (or Gates 38194, Dayco 89286)
• Idler Pulley PN: AC Delco 38006 (or Gates 38006, Dayco 89006)

Note: Always verify part numbers with your VIN as variations can exist based on specific option packages (e.g., heavy-duty towing, different alternators, etc.).

Belt Routing

The serpentine belt on your 2014 Chevrolet Silverado 1500 connects various accessories to the engine's crankshaft. Before you begin any work, STOP and take a clear photograph of your current serpentine belt routing! This will be your most valuable guide during reinstallation.

Here's a common text-based routing path for the 2014 Silverado 1500 (V6/V8 engines):

1. Start at the Crankshaft Pulley (the lowest, largest pulley at the front of the engine).
2. From the crankshaft, the belt typically goes up to the A/C Compressor Pulley (usually on the lower passenger side).
3. From the A/C compressor, the belt routes over the smooth Idler Pulley (often located above the A/C compressor or between it and the alternator).
4. Next, the belt wraps around the Alternator Pulley (usually high on the passenger side).
5. From the alternator, it makes its way to the Power Steering Pump Pulley (commonly located on the driver's side, mid-to-high).
6. The belt then goes around the Water Pump Pulley (usually centrally located, high on the engine).
7. Finally, it passes under the Serpentine Belt Tensioner Pulley (typically located on the driver's side, below the power steering pump or to the right of the water pump, featuring a square drive hole for a tool).

This path ensures all accessories are driven correctly. Remember to consult your photo for exact placement!

How to Replace the Serpentine Belt

Replacing the serpentine belt on your Silverado is a manageable DIY task, but it requires the correct procedure:

1. Safety First: Ensure the engine is off and cool. Disconnect the negative battery terminal.
2. Locate the Tensioner: Find the serpentine belt tensioner. It will have a square hole (usually 3/8-inch or 1/2-inch drive) for a breaker bar or a specific serpentine belt tool.
3. Relieve Tension: Insert a 3/8" or 1/2" drive breaker bar (or the serpentine belt tool) into the square hole on the tensioner. Rotate the tensioner to relieve tension on the belt. This will typically be a clockwise or counter-clockwise rotation, depending on the tensioner's orientation.
4. Remove the Old Belt: While holding the tensioner in the loosened position, slip the old belt off one of the pulleys (e.g., the idler or alternator).
5. Inspect Pulleys: With the belt off, take this opportunity to spin each pulley (alternator, A/C compressor, power steering, idlers, water pump). Listen for grinding noises or feel for excessive wobble, which could indicate a failing bearing. Check the tensioner for proper spring tension and smooth movement.
6. Route the New Belt: Following the photograph you took earlier (and the routing description above), carefully route the new belt around all pulleys EXCEPT the tensioner or an easily accessible idler.
7. Final Tensioning: Once the belt is mostly routed, again relieve the tensioner with your tool and slip the belt over the last pulley. Slowly release the tensioner, ensuring the belt seats correctly in all pulley grooves.
8. Double Check: Before starting the engine, visually confirm the belt is seated properly on every pulley.
9. Reconnect Battery: Reconnect the negative battery terminal.
10. Test Run: Start the engine and listen for any unusual noises. Observe the belt for proper tracking.

Replacement Interval

Chevrolet generally recommends inspecting the serpentine belt at every oil change and replacing it if signs of wear are present. As a general guideline, most technicians recommend replacing the serpentine belt between 60,000 to 100,000 miles or every 5-7 years, whichever comes first. If you live in extreme climates or regularly tow heavy loads, more frequent inspections and earlier replacement may be prudent.

Signs of a Failing Belt or Tensioner

Don't wait for a complete belt failure, which can leave you stranded. Be aware of these warning signs:

• Squealing or Chirping Noises: This is the most common symptom. It often indicates a worn, glazed, or misaligned belt, or a failing tensioner/pulley.
• Cracks, Fraying, or Glazing: Visually inspect the belt. Deep cracks, fraying along the edges, or a shiny, glazed appearance on the ribbed side are all indicators it's time for replacement.
• Loss of Power Steering or A/C: If the belt slips or breaks, accessories like the power steering pump, A/C compressor, and alternator will stop functioning.
• Overheating: The water pump, driven by the serpentine belt, circulates coolant. A failing belt can lead to engine overheating.
• Battery Light On: A broken or slipping belt will prevent the alternator from charging the battery, illuminating the battery warning light.
• Wobbly or Noisy Tensioner/Idler Pulleys: If you notice excessive wobble in a pulley or hear grinding/whining noises coming from them, the bearings are likely failing, and the pulley(s) should be replaced along with the belt.
• Loss of Belt Tension: A weak tensioner spring can lead to a loose belt, causing slipping and noise.

Catching these signs early can save you from a more significant repair and inconvenience.
