ATRACYPART Coolant Reservoir Tank for 2014–2021 Ram ProMaster 1500/2500/3500 — 1L Pressurized ABS with Cap

ATRACYPART's 603-832 coolant reservoir is a direct-fit, pressurized 1L replacement tank engineered to match OEM form and function for 2014–2021 Ram ProMaster 1500/2500/3500 models.

Designed to replace OE numbers 603-832, 52014880AA, and 68097622AA, this reservoir supplies a sealed, pressurized overflow chamber that maintains coolant volume and system pressure. Molded from durable ABS plastic, it resists heat and corrosion found under the hood, and ships with a cap and reinforced hose connections for tool-free installation in most cases.

How does this reservoir match my vehicle's original part?

The ATRACYPART reservoir is manufactured to OEM-equivalent dimensions and connection points so it installs in the original mounting locations without modification. It replicates the pressurized design and cap function, preserving cooling system pressure and overflow control.

• Direct-replacement for OE 603-832, 52014880AA, 68097622AA
• Three mounting holes aligned to factory brackets
• 1-liter capacity with factory-style pressurized cap
• Reinforced hose joints to reduce breakage and disconnection

Will the material and construction withstand under-hood conditions?

Yes — the tank is formed from high-quality ABS engineered for thermal resistance and long service life. The smooth surface finish reduces stress points, while the plastic formulation resists common automotive fluids and corrosion.

• Durable ABS construction for heat and chemical resistance
• Improved surface finishing to minimize cracking risk
• Designed for consistent performance in harsh environments

How easy is installation and what comes in the box?

Installation is straightforward for anyone comfortable with basic vehicle maintenance: remove the worn reservoir, transfer any necessary hoses and fittings, and bolt the new tank into the factory location. The unit arrives with the reservoir cap installed and strengthened hose connections to make reassembly faster and more reliable.

• No drilling or thermal welding required — fits factory mounting points
• Includes reservoir cap and reinforced hose junctions
• Compatible with factory hoses and clamps used on 2014–2021 ProMaster models

What performance should I expect once installed?

Once fitted, the reservoir maintains proper coolant overflow capacity and contributes to system pressure stability, which helps the cooling system regulate temperatures under normal driving loads. It’s built to be a long-lasting replacement that reduces the likelihood of leaks and pressure-related failures.

• Maintains correct coolant volume and pressure range (cap rated 20.3 PS)
• Reduced leak risk thanks to reinforced joints and quality molding
• Supports dependable cooling system operation across typical duty cycles

Who is this for? If you own a 2014–2021 Ram ProMaster 1500, 2500, or 3500 and are dealing with a cracked, leaking, or otherwise defective coolant reservoir, the ATRACYPART 603-832 tank is built to be an OEM-style replacement. It’s aimed at DIY mechanics, fleet maintenance teams, and professional installers looking for a durable, pressurized 1L reservoir that installs without modification and restores proper coolant overflow and pressure control.
