* Brand: OEM (Original Equipment Manufacturer) parts from GM will be the most expensive. Aftermarket brands offer a range of prices and quality. Some reputable aftermarket brands are more expensive than others, reflecting their perceived quality and warranty.
* Where you buy it: Dealerships will charge the most. Auto parts stores (like AutoZone, Advance Auto Parts, NAPA, etc.) will typically be cheaper. Online retailers (Amazon, eBay) can offer competitive pricing, but be sure to check reviews carefully.
* Labor costs (if you're not installing it yourself): This is a significant expense. The cost of labor will vary by location and the shop's hourly rate.
Rough Estimates:
* OEM Oil Pump: Expect to pay anywhere from $150 to $300 or more.
* Aftermarket Oil Pump: You might find them for $50 to $200, depending on the brand and quality.
It's crucial to get a quote from a parts store or mechanic before you begin any repairs. Calling a few local auto parts stores and getting prices on an oil pump for your specific engine (3.5L or 3.9L for the 2006 Impala) is the best way to determine a realistic cost. Don't forget to factor in labor costs if you're not doing the installation yourself.
