1990–1996 Nissan 300ZX Radiator & Cooling FAQ's

Please read our FAQs page to find out more.

What cooling mods are essential on a Z32 TT?

A high‑efficiency aluminum radiator, sealed shrouds/under‑trays, and clean oil coolers reduce heat‑soak. The factory clutch fan with a full shroud moves a lot of air—retain or replicate its performance.

How do I bleed the Z32 cooling system correctly?

Elevate the nose, open bleeders, and run the heater to purge air. Recheck after heat cycles—air pockets can spike temps and stress seals.

Is an oil cooler upgrade necessary?

Turbo cars benefit from thermostatic oil coolers and ducting to keep oil temps in range on track or in hot climates.
