✓PRESSURIZED 1.5 L CONFIGURATION:The included cap has a listed maximum pressure rating of 105 ±15 kPa. The 1.5 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 material rated from -30°C to 120°C. The translucent section makes coolant-level checks easier without opening a hot pressurized system. This version has no coolant-level sensor function. Replaces 603-973.
✓WHY DRIVERS REPLACE THE RESERVOIR:Cracks, seam or hose-neck seepage, dried coolant residue, falling coolant levels and repeated top-offs 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 more than the reservoir body. Cap rating, cap-neck fit, molded sealing surfaces, hose connections, clamps and the vehicle’s filling and bleeding procedure all affect cooling-system operation. BDFHYK focuses on these practical interfaces without making unrelated performance claims. Compare the original tank shape, mounting points, hose layout, sensor configuration and replacement number before ordering.
