aFe 011-16 GM Diesel Trucks V8-6.6L LML Engine Oil Pan Black POWER Pro Series w/ Machined Fins

Better Cooling, Bigger Capacity, Tougher Than Factory

The aFe BladeRunner engine oil pan 46-71080B is precision-machined from aluminum alloy and engineered to replace the factory stamped steel engine oil pan with a unit that runs cooler, holds more engine oil, and provides significantly greater protection during extreme driving conditions. Built specifically for the 2011-2016 Chevrolet Silverado 3500 HD, the 46-71080B features deep machined cooling fins across the exterior surface that increase surface area and dissipate heat into the ambient air, while the reinforced drain plug boss provides a long-lasting seal even after repeated service intervals. This is a direct bolt-on replacement using factory gasket surfaces and factory mounting hardware.

Key Features

• Material: aluminum alloy, CNC-machined for precise fitment
• Exterior machined cooling fins increase surface area for heat rejection
• Increased fluid capacity over factory engine oil pan
• Reinforced magnetic drain plug boss for a long-lasting seal
• Direct bolt-on using OEM gasket surface and factory mounting hardware
• Resists corrosion, thermal fatigue, and impact damage
• Finish: black anodized coating for corrosion resistance
• Backed by aFe Power limited manufacturer warranty

Frequently Asked Questions

Yes. The 46-71080B includes a magnetic drain plug and the gasket or sealing hardware required for installation. Always use a new gasket when installing to ensure a leak-free seal at the mating surface.

Additional capacity varies by platform. The increased reservoir depth adds extra engine oil volume compared to the factory pan, which helps maintain consistent fluid temperatures and reduces the risk of thermal breakdown during extended high-load operation. Check the aFe Power product page for exact capacity figures for your application.

Yes. The included magnetic drain plug attracts fine ferrous particles circulating in the engine oil, trapping them at the drain point rather than recirculating them through bearings and machined surfaces. Inspect the magnet at every drain interval.

The 46-71080B uses the same oil gallery port locations as the factory pan. If your existing cooler connects to factory oil gallery ports on the block or filter housing rather than the pan itself, it remains compatible. Confirm your specific cooler connection point before ordering.

The 46-71080B matches the factory pan profile. If you have aftermarket suspension or underbody protection, test-fit before final installation to confirm clearance with the increased depth of the aluminum pan versus the factory stamped steel unit.

Clean both the block and pan mating surfaces thoroughly. Use the supplied gasket or apply a thin bead of the appropriate RTV sealant as specified in the instructions. Torque all pan bolts in a cross pattern to factory specification. Never over-torque aluminum pan bolts, as this can crush the sealing surface.

In most applications, the factory undertray and splash shield are compatible. If the aluminum pan adds depth compared to the factory unit, a minor gap in the undertray is normal and does not affect function. Confirm fitment visually during installation.

aFe Power backs this pan with a limited manufacturer warranty on materials and workmanship. Coverage does not include leaks resulting from improper installation, over-torquing of pan bolts, or failure to use the supplied gasket. Contact aFe Power for full warranty terms.

Installation Overview

1. Warm the engine to operating temperature to thin the fluid, then safely lift and support the vehicle
2. Place a drain pan beneath the factory engine oil pan and remove the drain plug to drain completely
3. Remove the factory engine oil pan bolts in a cross pattern and lower the pan carefully
4. Clean all mating surfaces on the block and pan rails with a gasket scraper and solvent
5. Install the supplied gasket or apply RTV sealant as directed in the instructions
6. Lift the new 46-71080B into position and hand-thread all bolts before tightening
7. Torque all pan bolts in a cross pattern to factory specification, never over-torque
8. Install the new magnetic drain plug with a fresh sealing washer, torque to spec
9. Refill with the correct grade and quantity of engine oil, start the engine, and check for leaks
10. Allow the engine to reach operating temperature and recheck the drain plug and pan gasket for seepage
