How do you install an egr cooler?

To install an EGR cooler, first, ensure the engine is cool and disconnect the battery. Remove the necessary components, such as the intake manifold and any associated hoses, to access the EGR cooler. Install the new EGR cooler by aligning it with the mounting points and securing it with bolts, then reconnect all hoses and components. Finally, refill any lost fluids, reconnect the battery, and run the engine to check for leaks and proper operation.
