About This

• FITMENT FOR SKY, SOLSTICE:For Saturn Sky 2007-2010 2.0L I4 Turbo Gas or 2.4L I4 Gas Naturally Aspirated. For Pontiac Solstice 2006-2009 2.4L I4 Gas Naturally Aspirated; 2007-2009 2.0L I4 Turbo Gas. Verify the model, year and engine because the Solstice 2.0L has a shorter supplied fitment range.
• FITMENT FOR SATURN ION:For Saturn Ion 2003-2007 2.2L I4 Gas Naturally Aspirated; 2006-2007 2.4L I4 Gas Naturally Aspirated; 2004-2007 2.0L I4 Supercharged Gas. Confirm the year, engine, aspiration type, original reservoir and replacement number before ordering.
• PRESSURIZED 1.3 L CONFIGURATION:The included cap has a listed maximum pressure rating of 105 ±15 kPa. The 1.3 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 transparent body makes coolant-level checks easier without opening a hot pressurized system. Configured for applications using an external coolant-level sensor; confirm the original sensor and connector before ordering.
• REPLACEMENT REFERENCES:Cross-references 603-097, 10368831 and 63515605. Compare the replacement number, reservoir shape, mounting points, cap neck, hose connections and external sensor configuration because similar-looking reservoirs may use different physical arrangements.
• 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, sensor seating, correct filling and bleeding all affect operation. Continued coolant loss or elevated engine temperature requires complete cooling-system diagnosis.
