About This

• FITMENT FOR CENTURY CLASS:For Freightliner Century Class 2001-2002 8.5L, 11.1L; 2001-2004 10.3L; 2001-2003 10.8L, 15.8L; 2001-2007 12.7L, 12.8L, 14.0L, 14.6L. All listed Century Class applications use turbocharged diesel engines.
• FITMENT FOR COLUMBIA:For Freightliner Columbia 2001-2003 10.3L; 2001-2005 10.8L; 2003-2007 12.7L, 12.8L, 14.0L, 14.6L, 14.9L, 15.8L; 2004-2005 8.9L. All listed Columbia applications use turbocharged diesel engines. Verify the model, year, engine displacement and original reservoir before ordering.
• PRESSURIZED 8 L CONFIGURATION:The included cap has a listed maximum pressure rating of 105 ±15 kPa. The 8 L capacity is measured at the MAX fill level rather than the brim, leaving the intended coolant expansion space. The white/natural PP reservoir is rated from -30°C to 120°C for normal commercial-truck engine-compartment temperature cycles. A sensor interface is provided; confirm the original sensor and connector configuration before ordering. Replaces 603-5201, 575.1011, S-20397, S20397, 0520529000, 0523045000, 0523045001.
• BUILT FOR PRACTICAL TRUCK REPLACEMENT NEEDS:Cracks, seam or hose-neck seepage, dried coolant residue and repeated coolant top-offs can indicate deterioration of the original reservoir or its connections. During routine fleet inspections, also check the cap area, hose joints, mounting points and sensor connection. Replacing the reservoir addresses tank-related leakage, but continued coolant loss or elevated engine temperature requires complete cooling-system diagnosis.
• BDFHYK SYSTEM-LEVEL APPROACH:Reliable pressure retention depends on the reservoir body, cap rating, cap-neck sealing, hose connections, clamps, sensor seating and correct filling and bleeding. BDFHYK focuses on these practical cooling-system interfaces without making unrelated performance claims. Compare the original tank shape, mounting layout, hose positions, sensor interface and replacement number before installation.
