Product Overview
The Sinister Diesel Basic Solution™ Kit is designed to address two of the most common failure points on the early 6.0L Powerstroke—the oil cooler and EGR cooler.
When the factory oil cooler begins to plug with debris and casting sand, coolant flow through the cooler is reduced. As coolant flow decreases, EGR cooler temperatures rise, often leading to EGR cooler failure, coolant loss, white smoke, overheating concerns, and expensive repairs.
This kit combines the essential components needed to replace those failure-prone parts while providing the gaskets, seals, and hardware necessary to complete the job correctly the first time.
Whether you're repairing a failed system or performing preventative maintenance on a higher-mileage truck, the Basic Solution™ Kit helps restore reliability and protect your engine from some of the most common 6.0L Powerstroke cooling system issues.
