What is the advantage of the N-FLO dual-pass design?

The dual-pass design means coolant flows across the radiator core twice. This increases the time the coolant spends in contact with the fins, allowing for more efficient heat transfer and better overall cooling performance compared to a single-pass radiator.

Does this radiator come with a radiator cap?

This Koyo radiator does not include a radiator cap. You will need to reuse your vehicle's original cap or purchase a compatible one separately.

What type of coolant should I use with this radiator?

It is recommended to use a 50/50 mixture of distilled water and a quality engine coolant designed for Japanese vehicles. Always refer to your vehicle's service manual and the coolant manufacturer's recommendations for proper use and compatibility.

Product Details

This Koyo N-FLO radiator features a dual-pass core design, meaning coolant travels across the radiator core twice instead of just once. This setup increases the coolant's contact time with the cooling fins, which helps to dissipate heat more effectively than a standard single-pass radiator. It's built specifically for the 1989-1994 Nissan 240SX equipped with the SR20DET engine and a manual transmission.

The N-FLO design is a well-built option for drivers who push their SR20DET engines, whether on the street or track. The increased cooling capacity helps prevent overheating, especially during spirited driving or in warmer climates. Koyo radiators are known for their solid construction and reliable performance, making this a popular choice for maintaining optimal engine temperatures.

Installing this radiator is a direct replacement for your factory unit, simplifying the process. Ensure you have the correct coolant mixture and follow manufacturer guidelines for proper filling and bleeding of the cooling system to get the most out of its improved cooling capabilities.
