Honda S2000 Radiator & Cooling FAQ's

Please read our FAQs page to find out more.

What cooling upgrades help an S2000 on hot track days?

An aluminum radiator, improved fans/shrouds, and silicone hoses increase heat rejection. Proper ducting keeps the core fed with cool air.

Is an oil cooler recommended for a hard‑driven S2000?

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

Do I need to bleed the S2000 cooling system after upgrades?

Absolutely. Follow the correct bleed procedure and verify fan operation—air pockets can cause hot spots and fluctuating temps.
