* LT1 5.7L V8: This engine used a specific power steering pump. You'll need to find a pump specified for this engine to ensure proper fit and function.
* 4.3L V6: The V6 also had its own specific power steering pump. Again, you need a pump designed for this engine.
To find the correct replacement pump, you should:
1. Identify your engine: Check your vehicle's identification number (VIN) or engine bay for the engine size.
2. Use the engine code and VIN: Use this information to search online auto parts retailers (like AutoZone, Advance Auto Parts, RockAuto, etc.) Their websites have search tools where you can enter your vehicle's details to find the correct part.
3. Check the old pump: The pump itself may have a part number cast into it. This number can be used to search for a direct replacement.
Important Note: Don't just buy a "generic" power steering pump. The flow rate and mounting points vary, and using the wrong pump could damage your steering system. Always specify the correct year, make, model, and *engine* when ordering a replacement.
