88-91 Honda Civic/CRX OEM Radiator - Auto/Manual Trans
Direct replacement radiator for 88-91 Civic and CRX, available in automatic or manual transmission configuration. Built to factory specifications and engineered to handle stock cooling demands without compromise. Bolt-in fitment means no modifications to your engine bay.
Do I need to flush my cooling system before installing this?
Yes. Old coolant can contain debris and sediment that will clog a fresh radiator. Flush the entire system, refill with distilled water, run it briefly, then drain completely before dropping in the new core.
Will this radiator work with my current hoses and water pump?
Factory OEM hose connections and ports match your original setup, so existing hoses fit without modification. Your water pump compatibility depends on whether you're running original equipment — verify your pump matches the transmission type (auto vs. manual) that you're ordering.
