BANKS POWER COOL RUNNER ENGINE OIL PAN 35135-B | 2017-2019 Duramax 6.6L L5P

The Banks CoolRunner Oil Pan helps extend motor oil life in your 2017-2019 GM 6.6L Duramax L5P. Derived from military engine technology, it rejects more heat, reduces aeration, and includes two extra quarts of oil. The Banks FlowThru Fins improve cooling and ensure complete oil drainage.

Engineered to Cool Motor Oil

The CoolRunner Oil Pan features 19 deep-cut external radiator fins that increase surface area exposed to air beneath the truck. Die-cast construction ensures smooth interior surfaces for optimal oil flow to the pickup tube and drain. An anti-cavitation dimple improves flow to the pump. Additionally, 15 internal fins absorb more heat than stock or other aftermarket options, while FlowThru Fins optimize thermal transfer and maintain optimal oil viscosity for engine protection.

Oil Flow Improvements

• 1/8" NPT port for auxiliary temperature sensor
• Holds 2 extra quarts of oil
• Facilitates full oil drainage during changes
• Internal fins guide oil to the pickup tube
• Anti-cavitation dimple redirects flow for optimal lubrication
• Reduces windage for extended oil service life
• Flush-mounted, downward-facing drain plug with O-ring for complete drainage

Sealing Enhancements

The CoolRunner employs an OE-style full-length squeeze gap for the inner perimeter of the pan, ensuring proper sealing and preventing debris from damaging the oil pickup or pump.

Die-Cast Construction

Unlike sand-cast competitors, the Banks CoolRunner is die-cast, producing smoother, denser, and near porosity-free surfaces for maximum precision and reliability. Long, thin cooling fins further enhance heat dissipation and efficiency.
