The Banks CoolRunner Oil Pan uses advanced military engine technology to enhance oil cooling, reduce aeration, and extend service life. Designed for the 2020-2025 GM 6.6L Duramax, this oil pan adds 2 extra quarts of oil capacity and features Banks FlowThru Fins to maximize heat rejection. With 86.1% more cooling surface area than stock pans, it ensures full oil drainage, preventing sludge buildup and maintaining optimal engine lubrication.
Unlike stock and other aftermarket oil pans, the Banks CoolRunner fully drains all engine oil, preventing sludge accumulation and ensuring cleaner, more efficient oil changes. Its military-derived design guarantees greater durability, reduced oil oxidation, and superior cooling, making it the best choice for extending the life of your Duramax engine.
Its precision die-cast A380 aluminum design includes 19 external cooling fins and 15 internal fins, along with an anti-cavitation dimple to improve oil flow and reduce pump restriction. The flush-mounted drain plug allows for complete oil drainage, and a 1/8" NPT port is available for an auxiliary temperature sensor.
Installation is secured with 26 stainless steel M6 bolts, and the pan’s full-length squeeze gap prevents RTV sealant from entering the engine. The Banks CoolRunner is engineered for superior performance without lowering factory clearance.
