Typical failure mode of the OEM radiator. The crimped section got weaker and started to separate resulting in coolant leaking from the middle section.




New all aluminium Koyo Racing rad. Gave it good flush before the installation.

As reported earlier, I normally buy it from one specific vendor in US with Koyo US parts no. V2032.
However, it was out of stock at Koyo US with no information on the next production schedule so after discussing the matter with the owner, we bought it from drmikey. Thank you, Mike.




The one we received had parts no. KV082303R that is the same one used by Koyo Japan for their NSX radiator sold in Japan at higher price.






As expected, struggled to remove the heavily corroded bolts at the bottom side of the rad fan shroud but other than that, just straight swap and the new radiator slides into its original place with no modifications required.


Just needs replacing remaining coolant hoses before the fireup.


Getting there.
