Mazda RX-8 Mizu Aluminum Radiator Fan Shroud Install

Okay guys/gals I will be documenting the install of the Mizu aluminum radiator, fans, and shroud setup. I will be getting before and after data VIA my Cobb AP and posting up my findings. I currently have the Cobb tune turning the stock fans on earlier. I will go to a stock tune to get the initial data.

I received the items in perfect condition from www.sparkplugs.com. My initial impression is good. The radiator and shroud kit look awesome and fitment seems spot on. I put everything together and had no issues.

I will post up as I proceed with the install.

Also remove under tray.

Remove mounting bolts for condenser and pull forward (if you have one)

Radiator and fan pack will go in as one unit.




Fill and burp the system as referenced in the FSM. Start the car and bring it up to operating temps and check for any leaks.

I have before data and I will get some logged data tomorrow or Tuesday in near 100F driving conditions. All in all it was a easy install and the only gripes I have are the location of the drain plug and the fact that two wire weather safe connectors are not included with the fan shroud kit. The hole in my aluminum under tray is significantly larger than the hole in the stock tray. This will make it a bit messy if you plan to drain the fluid with the tray on. My tray is easily unbolted from the uprights but those with the stock tray may have a difficult time.

It's not really important but it should be noted that the Mizu fans are quiet in comparison to the stock fans.
