Installation Notes and Tips

Verify inlet and outlet sizing, core dimensions, and vehicle fitment before installation. Inspect hoses, clamps, and coolant condition during replacement, and confirm the cooling system is properly bled after service. For 2012 Honda Civic USA-built Denso applications, match the original radiator specification before installation.
