Nissan 350Z Mizu Radiato, Fans, and Hoses Installation

I got the opportunity to review the http://www.mymizu.com/ Mizu Cooling Solutions radiator, cooling fans and silicone hoses. My car was running a Mishimoto radiator for the past 3 years, it is pretty much a knock off of the Koyo 36mm radiator. Old cooling system stripped out, ready for fun.




First thing I did when I got down to www.paladinlasvegas.com was unbox the Mizu and get the old radiator out to compare them side by side.





Not easy to see, but the Mishimoto measured out at 37mm while the Mizu measured out at 44mm, but what you can see is the upper and lower tanks are massive on the Mizu. Bigger tanks = more fluid, that added capacity is usually a good thing.

Time to slide it in place, this is where the fun begins. I've installed a couple 36mm Koyo's, the 54mm Koyo, obviously the Mishimoto and its always a fight with the lower AC condensor mounting points. First time, it went right in, also shocking because of the tank size. No cutting of the core support needed (unlike on the 54mm and 56mm cores radiators) and the upper mounting posts were actually in the proper location unlike my prior radiator.

Little tip to make things easier. On the passenger side remove the coolant reservior and the bracket before you slide the radiator in or out of the car. The the AC line bracket on the drivers side on the frame rail right behind the radiotor, unbolt it.



Next it is time to wire up the fans. This the the diagram that I8acobra came up with 4 years ago when we wired up istans car. Pretty crazy, I8acobra now works at Paladin Advanced, same shop we were doing my car at.

Fans are all wired up, FYI , when reading the schematic the color of wires is the chassis harness, not the wires after the cannon plugs that connect directly to the factory fans.



All wired and taped up, a pic from the top. Between the fan shroud and polished radiator, it is pretty. It is also very thin compaired to the stock shroud, very nice to have because of clearance problems on the FI cars. Then the show guys, this just adds some nice bling while pushing a lot more air that stock .



Another view, dam this thing is slim.



Hoses are the 2 piece set, upper and lower. Just like every other hose kit i have installed the upper hose needed some trimming to fit. The hose needs to be shortened roughtly 3/4 to fit without having a kink. Very simple to do, then i used a pocket torch to smooth the cut ends. They still look showquality when finished. Hoses installed and time to fill it up!!!



I really hate the bleeding process. First i tried the vacumm fill, all that did was create air pockets thru the entire cooling system. So I next broke out the spill free funnel

So nice to have, i bought one for home use. I still do a lot of the work out of the garage at my condo. While my car was running and waiting for the thermostat to open time to get some work done on the thmotorsports Circuit Battle Subaru STI



Back in the morning to finish this up. Not to mention, way to much to write up in one post. thmotorsports
