Engineered to Cool Motor Oil
The Banks Oil Pan for the Duramax out-performs and out-cools the competition thanks to years of racing and military engine development. The19 deep-cut huge external radiator fins provide more surface area to the cool air moving under the vehicle.The die-cast process provides a smoother interior surface which improves oil flow to the pickup tube and drain.15 internal fins absorb more heat from the oil than a stock or any other aftermarket pan.
Engine heat is efficiently drawn from the sump where the hottest oil sits. Cooler oil retains the proper viscosity, which means metal-on-metal surfaces remain properly lubricated. With better internal heat absorption surface area and more external heat radiation surface area, your motor oil stays within its optimum operating temperature, which prevents breakdown even when towing up a grade.
Oil Flow Improvements
The CoolRunner oil pan features a 1/8" NPT port for an auxiliary temp sensor, is able to hold an additional two quarts of oil compared to stock, and allows for complete oil drain free from the sludge known to stay within the stock pan. Unlike competitors, which feature small grooves that run against the oil's return flow and disrupt the oil pickup tube's action, the CoolRunner's deep fins properly direct fluid to the oil pickup. The area under the oil pickup tube features a unique anti-cavitation dimple which smoothly redirects oil flow upwards. Thanks to a high static oil level, pressure on the pickup tube inlet prevents oil from escaping during an oil change. This leaves almost half a quart of liquid sandpaper in your engine.
Sealing Enhancements
Duramax oil pans use an RTV-style liquid gasket that must fully seal to prevent leaks. Poorly designed pans with an improper sealing surface can result in leaks or damage from strands of RTV falling in, clogging the oil pickup tube, or jamming the pump. Borrowing from decades of reliable military development, the CoolRunner uses an OE-style full-length squeeze gap that runs the entire inner perimeter of the pan. This precision-machined feature prevents small RTV strands from breaking off, falling into the sump, and damaging your engine.
Die-Cast vs Sandcast
All Banks lubrication cooling products are die-cast, not sand-cast like competitors. Die-Cast has superior precision, since die-cast part is denser, smoother, and has virtually no porosity compared to the sand-cast part. Sand-cast parts often retain the sand they were molded with. Sand is an abrasive material that can cause damage to bearings and cylinder walls. In other words, you don’t want sand in your oil. Finally, our long, thin cooling fins are only possible with a die-cast process. Although this process costs more, it's worth it.
Fluid Dynamics
- Internal cooling fins run inline with the drain port with streamlined passageways
- Anti-Cavitation dimple directly under oil pickup improves oil flow rate
- Downward facing port eases oil change process
- Low fluid aeration means longer fluid life
