Note: Trucks with front lift kits and drop brackets must remove the drop bracket in order to remove the stock oil pan and install the new Banks Cool Runner Oil Pan

Banks CoolRunner Oil Pan utilizes technology from our military engine program to extend oil life. The system rejects more heat and reduces aeration better than stock and all competitors. Two additional quarts of oil and Banks FlowThru Fins®aid in cooling. Unlike stock, the CoolRunner allows all fluid to drain during oil changes.

Part Number: 35135-B

Features

• Engineered for the best heat rejection, improved oil flow and full oil drainage
• Adds 2 additional quarts of oil capacity
• FlowThru Fins® efficiently transfer heat through the cover
• 72.4% more cooling surface area than stock
• Does not hang lower than factory front cross member
• Unlike stock, allows full engine oil drainage

Additional Info

Engineered to Cool Motor Oil

• 19 deep-cut huge external radiator fins provide more surface area to the cool air moving under the truck
• 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

Thermal Performance

• Banks' proprietary FlowThru Fins® 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

Oil Flow Improvements

• The area under the oil pickup tube features a unique anti-cavitation dimple which smoothly redirects oil flow upwards.
• 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

Full Oil Drainage

• The factory pan uses a drain plug that threads into a welded bung that protrudes inwards. This bung blocks oil from completely draining once it hits the top of the threaded bung
• Due to the high captive oil level that never drains, air cannot displace the fluid in the pickup tube. Therefore, the pickup tube retains dirty fluid during an oil change. This leaves almost half a quart of liquid sandpaper in the pan and pickup tube that pollutes the new oil
