Hybrid Racing has assembled an all-inclusive cooling kit for K20Z3/K24 engine swaps in 96-00 Honda Civic models. This 7-product bundle brings together the most essential components for efficient cooling, saving you both time and effort in your swap project.

Compact and Efficient K-Swap Halfsize Radiator & 12” Slim Fan

Central to the kit is the Halfsize Radiator, expertly engineered to fit your chassis without any modifications. It ensures the coolant inlet and outlet are correctly oriented to align with the K-series engine, providing a perfect fit without the need for custom mounts or chassis alterations.

Hybrid Racing radiators stand out with their dual-core, all-aluminum construction and precision TIG welding, offering a significant upgrade over standard OEM radiators with plastic end tanks that tend to crack.

Complementing the radiator is a 12” Slim E-fan, measuring just 2.25” in thickness. This slim fan efficiently maintains engine temperature, particularly in heavy traffic, and its compact size allows for additional engine bay modifications, including Hybrid Racing’s AC kit.

Durable Silicone Hoses & Reliable Clamps

The kit includes Hybrid Racing Radiator Hoses, specifically designed for compatibility with our radiators. They account for the radiator's thickness and the placement of the inlets and outlets, with strategic routing for a neater engine bay and fewer bends.

Matching Oil Cooler Hoses mirror the quality and performance of the Radiator Hoses.

Constructed from 4-ply polyester reinforced silicone, these hoses meet or exceed SAE20R4# standards, ensuring they are a durable and long-lasting solution.

Four stainless steel T-bolt band clamps are provided for securing the Radiator Hoses, while four standard hose clamps are included for the Oil Cooler Hoses, designed to prevent damage to the hoses.

Accurate Coolant Management with Advanced Sensors

The kit features new coolant sensors to provide reliable data, vital for accurate tuning. The Coolant Switch is essential for ensuring the e-fan operates at the appropriate times, maintaining optimal engine cooling.

These sensors are designed for direct threading into the Hybrid Racing radiator, facilitating installation by eliminating the need for special adapters or inserts.
