Product Description

The Hyper V-Core Series is the newest to the Koyorad All Aluminum Racing Radiator line up. An engine's cooling system in many newer vehicles are suffering due to limited space and crowding which affects air circulation. Our new ultra efficient Hyper V core was developed specifically for vehicles which see extreme heat, are limited in space, and where the factory inlet/outlet locations eliminate the option for a proper N-FLO design.

The Hyper V Series radiators have a specially designed fin and tube pitch which significantly increased its surface area while still allowing for excellent air circulation through the radiator. The Hyper V-Core series is the perfect solution where space savings and high performance is a must. All Koyorad Hyper V-Series All Aluminum Radiators are Nocolok brazed, designed as a factory fit, direct bolt in with no engine modifications necessary, and retain mounts for the stock fan shrouds and fans.

  • 36mm High Efficiency Core
  • Cap Not Included

*New Crossflow design requires slight trimming of the fan shroud near coolant outlet pipe. *

Fits:

  • 2003-2006 Nissan 350Z

Automatic Transmission owners PLEASE NOTE:

This high performance, aftermarket radiator DOES NOT include an integrated, internal transmission cooler.  Customers installing this radiator into an automatic transmission equipped vehicle must add an external transmission cooler.  Z1 Motorsports stocks and sells a variety of both universal and vehicle specific transmission coolers which can be found HERE.

Literally the best radiator! Went in and out smoothly, but just keep in mind you need to shave the fan shroud near the bottom of the radiator in order to have enough room for the lower radiator hose to fit. Also learn from my mistake, route the lower radiator hose AWAY from the ac belt because the belt will shred the hose and cause a leak if it’s not relocated properly (ask me how I know…), but other than that you should be fine!

OEM fan shroud along with upper and especially lower rad hoses need trimming. Drove my z for 3 months went to check oil and realized the lower rad hose had been contacting a pully. ordered new silicon one and trimmed 1.5 inches off lower end to pull it away from pulley. Other than that very happy with product.

OEM fan shroud and upper rad hose required trimming, but other than that was simple install.

First, it arrives as promised and the packaging is very good so it arrived intact. no fins bent at all. Now, the install is a little trickier but still simple enough for me to install, I had to cut the short upper rubber hose to fit since the cap is relocated to the passenger side , making the intake port closer to the engine. Bleeding was quite quick to do. Just follow the FSM to the letter.
