Detailed Description of the Dorman 54228 Cap

This engine coolant reservoir cap by Dorman is tailored for use in various Acura and Honda vehicles such as the Accord, Civic, Clarity, CR-V, CR-Z, Fit, ILX, Insight, and MDX. The cap’s 32 mm diameter and compact 1.5 inch dimensions ensure a precise fit on the reservoir neck.
