On certain vehicles with Chrysler EcoDiesel V6 engines, soot buildup in the intake manifold can cause a severe loss of power, smoke, and a burning smell. A dealer recall addresses failing EGR coolers on some EcoDiesels, but even if a cooler has been repaired under warranty, it may have already caused problems downstream that aren't immediately noticeable. Soot can accumulate inside the manifold, preventing proper operation of the IMRC system, while regeneration cycles to help clean the diesel particulate filter add even more soot and heat from the EGR system. Ultimately the soot buildup acts as an insulator, causing trapped heat to warp the manifold and create a leak. Manifold runners and the MAP sensor can also be damaged or melted, creating a burning polymer residue that adds to the fouling of the IMRC system. This upgraded Dorman OE FIX intake manifold features a deeper, more protective skirt on the sensor shroud, allowing the MAP sensor to be located farther out of the path of hot EGR gases. These engineering improvements can more effectively divert EGR heat and soot through the intake for a more reliable repair than the original design. This manifold can also help reduce cost by allowing still-functional sensors to be swapped into the new manifold, vs. the OEM replacement which can only be purchased with the MAP sensor, IMRC motor, and both runner sensors.
