Koyo Performance Radiator – Nissan 370Z / Infiniti G Series / Q60 MT

Application: Nissan 370Z (Z34) / Infiniti G Series (V36/CV36/HV36) / Infiniti Q60 (HV36/CV36) | VQ37VHR / VQ35HR / VQ25HR V6 Petrol RWD | Manual Transmission

Part Number: VH023478 / KV023478

The Z34 370Z and its Infiniti G Series / Q60 platform siblings share one of Nissan's finest V6 engine families — the VQ37VHR in particular is a high-revving, naturally aspirated powerplant that rewards modification and thrives on track. Keeping coolant temperatures stable is key to consistent performance, especially in spirited or circuit driving where the engine is under sustained load.

Koyorad's all-aluminium radiator is a direct bolt-in performance upgrade across the Z34 and V36 platform, engineered to the same factory fit and mounting points as the OE unit. Nocolok furnace brazed, precision TIG welded by hand, and triple pressure tested — it retains all OEM fan shroud mounts and stock hose connections with no modifications required.

Why Koyorad?

• Precise Tube & Fin Alignment — Strict quality control ensures optimal coolant flow and maximum heat transfer efficiency across the entire core.
• Nocolok Furnace Brazing — All tubes, fins, headers, and brackets are bonded in a state-of-the-art Nocolok furnace, creating a structure that resists vibration, road debris, and the elements.
• Billet Filler Neck — Precision-machined billet filler necks are fitted to every unit for superior strength, durability, and a reliable seal.
• OE-Specific Mounting — Application-specific mounting points for fan shrouds, inlet/outlet hoses, and top/bottom pins ensure a pain-free, no-modification install.
• Hand-Crafted Heliarc Welds — Each radiator is individually Heliarc welded by hand, creating the strongest possible aluminium-to-aluminium bond across all components.
