koxuyim Engine Coolant Expansion Reservoir for Ford Focus 2.0L (2012–2018) - Complete Tank, Cover & Hose

koxuyim Engine Coolant Expansion Reservoir is a direct-fit replacement tank, cap and radiator hose assembly engineered to replace OEM CV6Z-8A080-A and restore the cooling system for 2012–2018 Ford Focus 2.0L engines.

This complete front engine coolant reservoir kit from koxuyim includes the expansion tank, matching cover and radiator reservoir hose designed to match the original mounting points and fluid routing of the Ford Focus 2.0L (2012–2018). It replaces the factory part numbers 603-382, 603382, CV6Z8A080A, 8V618K218AE and equivalent OE references so you get a straightforward swap with minimal adjustments. Built from heat-resistant materials and tested for vibration durability, the assembly gives your cooling system a renewed overflow capacity and an OEM-like fit without extensive modification.

How does this reservoir fit my 2012–2018 Ford Focus?

koxuyim engineered this expansion tank to align with the factory mounting tabs, hose outlets and cap location used on the 2.0L Focus models across model years 2012 through 2018. The dimensions and connection points mirror the original equipment so installation is typically bolt-on.

• Replaces OEM numbers 603-382, CV6Z-8A080-A and related references.
• Includes reservoir, cover and radiator reservoir hose for a complete swap.

What materials and quality features should I expect?

The tank is molded from a high-temperature resistant plastic formulated for underhood durability and pressure cycling. koxuyim subjects each unit to fitment checks and basic leak testing so the tank resists typical heat and vibration experienced in daily driving.

• Heat- and vibration-resistant plastic to withstand engine compartment conditions.
• Precision molding for consistent hose and cap sealing surfaces.
• Pre-tested for basic leak integrity and dimensional accuracy.

What does the kit include and how easy is installation?

This listing supplies one front engine coolant reservoir tank, a matching cover and one radiator reservoir hose so you replace the whole subassembly at once. Installation is designed to be straightforward for DIYers with common tools: unclip the old tank, disconnect hoses, bolt the new tank into place and reconnect the hoses and cap.

• Package contents: 1x reservoir tank, 1x cover, 1x radiator reservoir hose.
• Direct replacement—uses factory mounting points and hose connections.
• Simple tools required: basic hand tools, drain pan and coolant refill.

Will this reservoir work with my existing cap and sensors?

The koxuyim reservoir is produced to accept the standard cap position and common overflow hose routing used on the specified Focus models. If your vehicle uses a sensor or unique cap variant, compare the cap thread and sensor port location to confirm compatibility before installation.

• Cap location matches OEM style; verify cap thread if reusing an original cap.
• Sensor port arrangement mirrors common factory layouts for these years.
• Contact support if your vehicle has nonstandard or aftermarket cooling components.

Who is this for? The koxuyim coolant expansion reservoir kit suits Ford Focus owners, independent mechanics and DIY enthusiasts who need a reliable, cost-effective replacement for a cracked, leaking or warped overflow tank on 2012–2018 2.0L models. It’s ideal when you want an all-in-one swap—tank, cover and hose—to restore coolant overflow capacity and routing without hunting for separate components. For fleet vehicles and repair shops, this part streamlines service by matching common OE part numbers and fitment expectations.
