The Dorman 603-382 is a direct-replacement pressurized engine coolant reservoir with cap, engineered to restore proper coolant containment and match the original fit for compatible Ford vehicles.

This replacement coolant overflow tank is made from heat- and vibration-resistant materials to handle the underhood environment while providing the same mounting points and hose connections as the OEM unit. Dorman designed this reservoir to be a like-for-like substitute for worn, cracked, or leaking tanks used on specific Ford C-Max, Escape, Focus, and Transit Connect model years. Before ordering, verify your vehicle year and trim with the garage tool to confirm compatibility.

How does this reservoir match my original part?

The 603-382 is molded and assembled to mirror the original reservoir’s shape, cap interface, and mounting locations so installation requires minimal modification. That alignment reduces installation time and avoids the common fitment pitfalls of generic tanks.

• Engineered to replicate OEM mounting brackets and hose ports
• Includes compatible pressurized cap seating and threads

Will this hold up in the engine bay environment?

Yes — Dorman uses robust thermoplastic materials selected to resist high temperatures, coolant exposure, and engine vibration. This construction helps prevent premature cracking, swelling, or leaks that occur with aged reservoirs.

• Heat-resistant material suitable for underhood temperatures
• Vibration-tolerant design for long-term durability
• Precision molding reduces stress points and weak seams

How easy is the installation for a home mechanic?

Installation is generally straightforward because the part is a direct replacement: it mates to the factory hoses and bolts into the original mounting points. Basic hand tools and attention to safe coolant draining procedures are usually sufficient for a DIY swap.
