CSF Race On Your Cooling Questions with our friends at Speedhunters

Ever wonder what the difference between a down-flow radiator or a cross-flow radiator is? Check the article for all the answers of questions you’ve probably had, but never knew.

Cooling Questions: Cross-Flow VS Down-Flow

Cooling Questions: Civic Down Flow Radiator
Cooling Questions: FR-S Cross Flow Radiator

CSF’s Honda Civic radiator is pictured first (CSF #2858). It’s a downflow while the Scion FR-S / Subaru BR-Z radiator following it (CSF #7050) is a crossflow type

A horizontally cored radiator is called a cross-flow radiator and a vertically cored radiator is called a down-flow radiator. There is no difference in these radiators if all variables remain the same. Vehicle manufactures select the type of radiator core they will use on a specific application based on their space restrictions (length and height) as well as their desired placement of inlet and outlet connections. If a radiator is a down-flow type, but is longer (length) than it is taller (height), then changing the design to a cross-flow type will most likely have a positive affect on the performance of the radiator. Although coolant will not move through the cooling system as quickly, the outlet temperatures can be decreased because heat dissipation is improved by lengthening the coolant path from side to side, which more effectively transfers excess heat from coolant to air before leaving the radiator.

Other great cooling questions in the article include how to properly duct your car, and the importance of hood vents in motorsports.

See why CSF makes the best radiators in the world, and the importance of good core technologies. With premium materials and rock solid engineering, is it any wonder how we make the best Porsche radiator in the industry to go along with our Euro and Sport compact lines?

Stay cool with CSF and SPEEDHUNTERS!
