The Banks CoolRunner Oil Pan for the 2017-2019 Duramax out-performs and out-cools the competition by leveraging decades of racing and military engine development.
19 deep-cut huge external radiator fins provide more surface area to the cool air moving under the truck.
The die-cast process provides a smoother interior surface which improves oil flow to the pickup tube and drain.
A smooth, streamlined area around the oil pickup with an engineered anti-cavitation dimple improves oil flow to the pump by reducing restriction at the filter inlet.
15 internal fins absorb more heat from the oil than a stock or any other aftermarket pan.
Banks proprietary FlowThru FinsTM maximize thermal energy transfer by lining up the internal and external features with each other.
Engine heat is efficiently drawn from the sump where the hottest oil rests. Cooler oil retains the proper viscosity, which means metal-on-metal surfaces remain properly lubricated.
With more internal heat absorption surface area and more external heat radiation surface area, your motor oil stays within its optimum operating temperature, which prevents oxidation or breakdown even when hauling up a grade.
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.
Both the internal cooling fins and dimple reduce windage common in other aftermarket designs and extend the service life of your oil.
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.
All Banks lubrication cooling products are die-cast, not sand-cast like competitors. Made with far greater precision, a die-cast part is denser, smoother, and has virtually no porosity compared to the equivalent sand-cast part.
Sand-cast parts can even retain the sand they were molded with. (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, we think it's worth it.
