In a typical Silverado, throttle body replacement costs usually fall in the hundreds to low thousands of dollars, with most customers seeing a bill around $400 to $900 at an independent shop. The final price depends on the engine, the parts chosen (OEM vs aftermarket), and whether a throttle relearn/calibration is required.
What influences the cost
The total price is driven by several factors: the type of throttle body you install (OEM new, remanufactured, or aftermarket), the engine in your Silverado (common options include 4.3L V6, 5.3L V8, 6.2L V8, and 3.0L Duramax), regional labor rates, and whether the shop performs a throttle relearn/calibration as part of the replacement. On many newer Silverado models, a throttle body relearn procedure is needed and can affect the final charge.
Cost ranges for a Silverado throttle body replacement
The following ranges cover typical options and what you can expect to pay before tax. The exact price will vary by model year, engine, and supplier.
- OEM new throttle body: roughly $320–$640
- Remanufactured/rebuilt throttle body: roughly $140–$280
- Aftermarket brand throttle body: roughly $100–$230
Prices can vary by model year and supplier; gaskets and seals are often sold separately and may add about $5–$20 if not included with the unit. In practice, the parts cost for a typical Silverado replacement generally ranges from about $140 to $640, depending on the option chosen.
After considering the parts themselves, the overall cost also depends on labor and any calibration work. The next section outlines common labor charges and related fees.
Labor and calibration can add significantly to the bill. Here’s how those costs typically break down.
Labor and related costs
Labor charges vary by region, shop, and whether you choose an independent shop or a dealership. The following are typical ranges you may encounter.
- Labor time: Most Silverado throttle body replacements take about 1 to 2 hours.
- Shop rate: Roughly $80–$150 per hour, depending on location and whether the shop is a dealership or indie shop.
- Total labor cost: Approximately $80–$300
- Calibration/relearn and diagnostics: Often $40–$100 if not included in the labor, with dealers sometimes charging more.
Many shops include the throttle relearn in the labor charge if they perform the procedure, while others bill it separately. If you have a warranty or use GM-approved parts, verify whether calibration is included in the quoted price.
DIY considerations
Replacing a throttle body yourself can save on labor if you’re comfortable with the task. You’ll pay only for the parts if you supply your own, plus any tools or diagnostic equipment needed for the relearn. Be aware that a throttle relearn or calibration is often required and may necessitate a scan tool and familiarity with the vehicle’s software procedures.
Summary
Bottom line: Replacing a throttle body on a Silverado is a multi-factor job, with total costs typically ranging from roughly $400 to $1,300 depending on engine, parts choice, and whether calibration is included. Independent shops generally fall toward the lower end of the range, while dealerships or high-cost areas can push the total higher. Always request a detailed written estimate that breaks out parts, labor, and any diagnostic or calibration fees, and confirm whether a throttle relearn is included.
