CSF 3-Row All-Metal vs. Koyorad HH 48mm Aluminum Radiator

Both are cooling upgrades for 1984–1989 Toyota 4Runner applications, but they use different construction methods and are best suited to different priorities.

CSF 3-Row All-Metal Radiator

• Traditional 3-row copper core with brass tanks
• Heavier than the Koyorad aluminum radiator
• Available for 22R / 22RE and 3VZ-E V6 applications within the supported year range
• Traditional copper/brass construction can often be repaired, soldered, or recored by a qualified radiator shop
• Best suited to owners prioritizing heavy-duty construction, broader engine coverage, and long-term serviceability

Koyorad HH Series 48mm Aluminum Radiator

• All-aluminum construction with a 48 mm high-density core
• Lighter than a traditional copper/brass radiator
• Designed for naturally aspirated 22R / 22RE manual-transmission applications
• Does not include an integrated automatic-transmission cooler
• Designed to retain the factory fan shroud on supported applications
• Best suited to owners prioritizing lightweight construction and a performance-oriented cooling upgrade

Important: Do not compare these radiators by row count alone. The CSF uses a traditional three-row copper/brass core, while the Koyorad uses a thick 48 mm high-density aluminum core. They use different core technologies to increase cooling capacity.

Choose the CSF if you want traditional all-metal construction, broader engine coverage, and serviceability. Choose the Koyorad HH if you have a naturally aspirated 22R / 22RE with a manual transmission and want a lighter, performance-oriented all-aluminum radiator.
