CSF Radiator How Tos


The Civic CSF radiator provide optimum cooling efficiency and keeps your engine from overheating. If you are modifying your vehicle or using it in competition style events, there are very few options that give you as much cooling power than these CSF Radiators.

What puts these CSF radiators ahead of the competition is their extensive cooling testing and technology. Part of this cooling tech is what CSF calls its B-Tube technology. Using cooling tubes that are shaped like the letter B instead of the standard oval tubes, CSF can use a thinner material that dissipates heat better than the competition. Despite the thinner cores, CSF race radiators are actually proven to be stronger than their counterparts without this unique design.

This is not for the EP3 Civic, or one equipped with the DOHC K series i-VTEC engine. Meant only for the 1.8 liter engine.
