Infiniti G37 Radiator & Cooling FAQ's

Please read our FAQs page to find out more.

What cooling upgrades keep a hard‑driven G37 consistent?

Aluminum radiators, upgraded fans, thermostats, and silicone hoses improve heat shedding. Proper ducting ensures the G37 cores see cool ambient air.

Is an oil cooler advisable on a tuned or tracked G37?

Yes—an oil cooler stabilizes viscosity and pressure so the VQ37 maintains a safe oil film at temperature under repeated high‑load use.

Do I need to bleed the G37 cooling system after upgrades?

Absolutely—follow the correct bleed procedure and verify fan operation. Air pockets cause hot spots and fluctuating temps on the G37.
