Stant 10244 Engine Coolant Reservoir Cap
OE Type Coolant Reservoir Cap for BMW, Volvo, and More
The Stant 10244 OE Type Reservoir Cap is an engine coolant reservoir cap for threaded filler necks on closed cooling systems. It uses a 22 psi pressure rating and durable plastic construction to help maintain proper cooling system pressure across a wide range of BMW, Mini, Fiat, Ram, and Volvo applications.
Key Features
- Stant OE Type Reservoir Cap for threaded filler necks
- 22 psi pressure rating for closed cooling systems
- Durable plastic construction
- Direct-fit style replacement for select BMW, Mini, Fiat, Ram, and Volvo models
- Part number 10244 for easy identification
Product Details
Built as an OE Type Reservoir Cap, the Stant 10244 is made to match the pressure requirements used in many late-model and legacy cooling systems. A properly functioning coolant reservoir cap helps the system hold pressure, which supports stable coolant circulation and consistent operating temperature. This part number 10244 is listed for a broad range of vehicles, including BMW 440i, 540i, X3, and X5 applications, along with Volvo XC90, S60, and 850 fitments.
Compatible With select BMW 230i, 330i, 430i, 530i, M3, M5, X1, X2, X3, X5, and X6 models; Mini Cooper, Cooper Clubman, Cooper Countryman, and Cooper Paceman; Fiat 500L; Ram ProMaster 1500, 2500, 3500, and ProMaster City; and multiple Volvo sedans and wagons. The Stant 10244 is a practical replacement when the original reservoir cap no longer seals or maintains the specified pressure.
What This Part Helps Address
- Coolant loss from a cap that no longer seals correctly
- Pressure-related cooling system instability
- Steam or overflow caused by a weak reservoir cap
- Temperature fluctuations tied to poor system pressure retention
- Replacement needs for a worn or damaged threaded coolant cap
Installation Notes and Tips
Verify the reservoir uses a threaded filler neck and confirm the required pressure rating before installation. Match the cap to the vehicle’s cooling system specification, then inspect the neck and sealing surface for cracks, debris, or coolant residue before tightening. For fitment reference, this part number 10244 is listed for 2017-2019 BMW 440i, 2018-2019 BMW 530e, and 2003-2011 Volvo XC90 applications.
Quality Assurance
Stant is known for OE-style cooling system hardware, and this reservoir cap is built to meet the listed 22 psi pressure specification for the applications shown.
