Have you ever heard of piston squirters, also known as piston cooling jets? In this episode, we take a deep dive into these hidden but crucial components inside our Land Rover / Ford 3.0L SDV6 Diesel engine (306DT)— an engine also found in the Ford F-150, various Jaguar models, and Land Rovers.
To demystify how these cooling jets operate, we built a custom test setup that allows us to see their function in action—something that usually remains hidden deep inside the engine. We explain in detail how the piston squirters work, their role in cooling the pistons under high load, and the differences between various applications of this engine across different vehicles.
Most people don’t realize that piston cooling jets aren’t the same across all versions of the SDV6 engine! We explore how and why these differences exist and what that means for performance, reliability, and rebuild considerations.
If you’re an engine enthusiast, a DIY mechanic, or just someone who loves seeing complex engine functions in action, this episode is packed with insights, technical explanations, and hands-on demonstrations.
