10 Blade Cooling Fan for Toyota Hilux Surf / 4Runner KZN130 / KZN185 / LN61 | 1st, 2nd & 3rd Gen 84-02

STOP THE HEAT: 10-Blade Cooling Fan Upgrade for Toyota 1KZ-TE Engine

Is your Toyota Hilux Surf running a bit too hot, especially when towing, on the track, or during hot summer months? The legendary 1KZ-TE engine is known for its durability, but inadequate cooling from the factory 7-blade fan can lead to overheating and, potentially, costly head damage.

Upgrade your peace of mind and your cooling capacity with our High-Performance 10-Blade Cooling Fan.

The Ultimate Cooling Upgrade

Our 10-blade fan is a direct, essential upgrade over the standard 7-blade factory fan, engineered to dramatically enhance airflow across your radiator and engine bay.

Key Benefits & Features:

40% Enhanced Airflow: By increasing the blade count from 7 to 10, this fan moves a significantly larger volume of air, providing superior cooling performance at all engine speeds.

Crucial Engine Protection: Specifically designed to combat the common overheating issues associated with the 1KZ-TE engine, helping to maintain optimal operating temperatures and prevent head cracking.

Direct Bolt-On Fitment: Designed as a seamless replacement for the original fan. No modifications are required for your Toyota Hilux Surf (1KZ-TE, 3.0L Turbo Diesel).

Built to Last: Manufactured from high-quality, durable materials to ensure long life and reliable operation in tough 4x4 conditions.

Don't wait for your temperature gauge to climb. Protect your engine investment today with the mandatory 10-blade cooling upgrade.

(Pro Tip: For maximum cooling efficiency, we highly recommend inspecting or refreshing your viscous fan clutch with new oil when installing the new 10-blade fan.)

Frequently asked questions

Will this 10-blade cooling fan fit my 1KZ-TE Hilux Surf?

Yes. The 10-blade fan is a direct bolt-on replacement for the factory 7-blade fan on the 1KZ-TE engine, fitted in the KZN130 (2nd Gen, 1989-95) and KZN185 (3rd Gen, 1996-2002) Hilux Surf and 4Runner. It uses the existing viscous fan hub, so no modifications are needed.

Will the 10-blade fan fit a V6 5VZ-FE Surf?

No — the 5VZ-FE V6 uses a different fan hub design. This kit is engineered for the 1KZ-TE diesel and the related 2L, 3L and 5L diesel engines. For V6 owners, the Max-Cooling Upgrade Kit has a V6-specific configuration.

Do I need to change anything else when installing this fan?

You don't have to, but we strongly recommend refreshing the silicone oil inside your viscous fan hub at the same time. A worn hub won't lock up properly and the extra blades won't reach their full benefit. If your thermostat is older than 5 years or 100,000 km, replace it at the same time too.

How much cooler will my engine actually run?

Real-world reports from customers show a 5-15°C drop in coolant temperature on hot climbs and when towing, depending on the condition of the rest of your cooling system (radiator, hub, water pump). The biggest gains come when paired with a fresh viscous hub and OEM thermostat.

Is this a direct bolt-on or do I need to modify anything?

It's a direct bolt-on swap. Remove the four bolts holding your factory 7-blade fan to the viscous hub, fit the new 10-blade fan, and torque the bolts back up. Install time is typically 20-30 minutes with basic hand tools.
