Product Details
✓FITMENT FOR FORD CROWN VICTORIA:For Ford Crown Victoria 1998-2011 4.6L V8 Gas Naturally Aspirated; 2006-2011 4.6L V8 Flex-Fuel Naturally Aspirated; 1998-2005 4.6L V8 CNG Naturally Aspirated. Verify the fuel type and year because the Gas, Flex-Fuel and CNG configurations have different supplied fitment ranges.
✓FITMENT FOR LINCOLN, MERCURY:For Lincoln Town Car 1998-2011 4.6L V8 Gas Naturally Aspirated; 2006-2011 4.6L V8 Flex-Fuel Naturally Aspirated. For Mercury Grand Marquis 1998-2010 4.6L V8 Gas Naturally Aspirated; 2006-2011 4.6L V8 Flex-Fuel Naturally Aspirated. For Mercury Marauder 2003-2004 4.6L V8 Gas Naturally Aspirated. Confirm the exact make, model, year, fuel type and original reservoir before ordering.
✓PRESSURIZED 2.05 L CONFIGURATION:The included cap has a listed maximum pressure rating of 110 ±15 kPa. The 2.05 L capacity is measured at the MAX fill level rather than the brim, leaving the intended coolant expansion space. PP construction is rated from -30°C to 120°C. The translucent lower body makes coolant-level checks easier without opening a hot pressurized system. This reservoir has no sensor functionality; match the original vehicle configuration before ordering.
✓REPLACEMENT REFERENCE:Cross-references 603-050. Compare the reference number, reservoir shape, mounting points, cap neck and hose connections because similar-looking reservoirs may use different physical configurations.
✓BUILT AROUND REAL REPLACEMENT NEEDS: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. BDFHYK treats the tank as part of a pressurized cooling system: cap rating, cap-neck sealing, hose connections, clamps, correct filling and bleeding all affect operation. Continued coolant loss or elevated engine temperature requires complete cooling-system diagnosis.
