This kit is designed to help increase the cooling to the #4 cylinder on the Subaru EJ series engines. This hose kit connects to an existing port on the back of the left hand side of the motor that is blocked off from the factory with a plug.

Compatibility:
All Subaru EJ Series Motors

Included in the kit:

10 Inches of Gates Engine Coolant Hose
-10 AN 45 Degree Push To Connect Fitting
-10 AN to Metric Straight Thread Adapter
Aluminum Crush Washer for Metric Straight Thread Connection
304 Stainless Steel 5/8” Barbed Tee Connection
Qty 4 Stainless Steel Hose Clamps
12mm Allen Socket with 1/2” Square Drive


Basic Installation Steps:

  • Drain coolant from engine below the level of the plug on the back of the engine

  • Remove factory coolant plug using the supplied 12mm allen socket

  • Install straight thread to 10AN adapter with included aluminum crush washer

  • Test fit 10AN 45 degree fitting with hose attached

  • Locate heater core hose that connects to firewall and mark where to cut and install stainless tee fitting

  • Trim included Gates heater hose (different chassis and models require slightly different hose lengths)

  • Install tee connector inline with existing heater hose with the center connection being used for the provided line, use hose clamps on all 4 barbed hose connections

  • Tighten 10AN connection, ensure the new hose does not rub on any other parts in the engine bay paying close attention to the steering shaft

  • Refill coolant and properly “burp” the system to remove all air introduced during the installation

    *Note: If you see corrosion or surface imperfections on the sealing face of the block you can apply Permatex or similar sealing material to the metric straight threads on the adapter fitting into the block for a secondary sealing point. NEVER apply any type of sealant or tape to the threads on AN fittings.

This is a universal kit, depending on the year and chassis this is being installed on the length of heater hose and the point at which you connect into the factory hoses will be slightly different. We will be posting more detailed instructions and photos for each unique application very soon.

The intent of this kit is to solve an imbalance in the factory cooling system on the EJ series motors. Subaru designed the cooling system to ensure that cylinder #4 ran slightly hotter than the rest of the cylinders, this allowed them to then tune the system so that if knock were to occur is would happen first on cylinder #4. While this simplifies the control system on a factory car it doesn’t allow tuners to get the most potential out of the engines, the tune is basically limited by an intentional design flaw in the cooling system. Since this type of modification (not just our kit) can effect knock response on your engine we recommend consulting with your tuner before installation and having your tuner review logs after installation. Professional installation is recommended.

Flimsy and cheap screws
Screws snapped off when I tried to drill htem in and no matter how I try to get the leg pieces in they will NOT stay. Falls apart, screws snap off, the middle axle holes arent even lined up so you cant install one of the pieces in the first place.

Easy to assemble. Works well. Looks nice.
Color: Light Grey, Color: Light Grey
Works for what we need. Easy to put together. Diagram provided was clear. One of the lil screws didn't fit perfectly, but it works well enough. Came with all the lil tools you need to assemble. Product frame is sturdy and hardware (seems heavy duty enough, metal and not plastic) all fits together very nicely. Would buy again if i need another one.

Great value!
Color: Light Grey
I purchased this for a divider in the sanctuary of our church. Making a private prayer corner.. It is way better than expected. Follow direction . When you make the "M" shape put close together. I had the letter tops to far apart and it complicated things. Otherwise it was awesome. Would definitely buy another one if needed
