Manage coolant expansion and keep a visible coolant level with the Dorman - OE Solutions Engine Coolant Reservoir 603-503. It installs as a direct-fit replacement for the 1994-2001 Acura Integra and 1997-2001 Honda CR-V, mounting in the front position where the factory reservoir sits.
Overflow reservoir: holds coolant as it heats and expands, then returns it to the system as the engine cools.
Front position: cataloged for the front-mounted location on the listed applications.
Direct-fit replacement: designed to replace a cracked, leaking, or missing original tank for the listed vehicles.
Over time an original reservoir can crack, split at the seams, or leak around the cap and fittings, leading to coolant loss and a hard-to-read coolant level. If a failed reservoir is the cause of your coolant seepage or a repeatedly low level, this tank replaces it. Always diagnose the source of any coolant loss before replacing parts, since leaks can originate elsewhere in the cooling system.
