Coolant Flow in Subaru EJ-Series Heads

In this video I dive into coolant flow through the heads of Subaru engines and I discuss why cylinder number four has so many issues! This Subaru DiY video is the second in a multi-part series about COOLANT FLOW through Subaru EJ-SERIES engines, and why you may want to consider purchasing a ‘REVERSE COOLING MOD’ (aka 'COOLANT BALANCE') kit for your Subaru.

This series took a significant amount of effort to create and I think it’s one of the most comprehensive dives into Subaru cooling and the primary achilles-heal in Subaru EJ-series engines - the NUMBER FOUR CYLINDER! I hope this deep-dive into coolant flow becomes a valuable resource for Subaru enthusiasts all over the World!

This video is part of a "Build Series" (see "Playlists" tab for all videos) for my 1998 Rally Blue Pearl RSTi Coupe (Impreza 2.5RS swapped with a EJ205 turbo engine), which is 1 of only 720 sold in the USDM for 1998. This RSTi Build has come a long way and includes a full archive of videos documenting how to: (1) Pull a EJ-series turbo engine, (2) Replace the head gaskets, (3) Add key upgrades to increase long-term reliability, and (4) Restore the interior to OEM specifications.

*2020 UPDATE: After working as a professional Hydrogeologist for 15 years, I've decided to embrace the reward I've found in creating YouTube content, my passion for competitive Motorsports, and building relationships with all the people and small businesses that make these communities work. I'M GOING FULL-TIME as a YouTube Creator starting Dec 2020! Hope you'll join me on this journey into the unknown!
