• PRESSURIZED 1.95 L CONFIGURATION:The reservoir is supplied with a cap for the listed pressurized cooling-system configuration. Its 1.95 L capacity is measured at the MAX fill level rather than the brim, leaving the intended coolant expansion space. The black upper section and translucent lower body use PP-GF10 material rated from -30°C to 120°C. The translucent section allows coolant-level checks without opening a hot pressurized system. Configured for applications using an external coolant-level sensor; confirm the original sensor and connector before ordering. Replaces 603-283, 2115000049, FRT2411C, SK603283, Z49022, 210501061564.
• WHY DRIVERS REPLACE THE RESERVOIR:Cracks, seam or hose-neck seepage, dried coolant residue, repeated coolant top-offs or a low-coolant warning may indicate deterioration of the original reservoir or its connections. Replacing the tank addresses reservoir-related leakage and sealing problems, but continued coolant loss or elevated engine temperature requires diagnosis of the complete cooling system.
• BDFHYK SYSTEM-LEVEL APPROACH:Pressure retention depends on the reservoir body, cap fit, cap-neck sealing, hose connections, clamps and external sensor seating. BDFHYK focuses on these practical cooling-system interfaces without making unrelated performance claims. Confirm the exact model, year, engine, trim, four-door sedan body style, original tank configuration and replacement number before ordering.
