Product Details
✓FITMENT FOR CHEVROLET EQUINOX:For Chevrolet Equinox 2010-2017 2.4L I4 Gas Naturally Aspirated; 2012-2017 2.4L I4 Flex-Fuel Naturally Aspirated; 2011-2012 3.0L V6 Flex-Fuel Naturally Aspirated; 2013-2017 3.6L V6 Gas or Flex-Fuel Naturally Aspirated. Verify the engine size, fuel type and year because each configuration has a different fitment range.
✓FITMENT FOR GMC TERRAIN:For GMC Terrain 2010-2017 2.4L I4 Gas Naturally Aspirated; 2012-2017 2.4L I4 Flex-Fuel Naturally Aspirated; 2010-2012 3.0L V6 Gas Naturally Aspirated; 2011-2012 3.0L V6 Flex-Fuel Naturally Aspirated; 2013-2017 3.6L V6 Gas or Flex-Fuel Naturally Aspirated. Confirm the original reservoir and replacement number before ordering.
✓PRESSURIZED 0.625 L CONFIGURATION:The included cap has a listed maximum pressure rating of 105 ±15 kPa. The 0.625 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 REFERENCES:Cross-references 603-338, 603338, 15066786, 15075118, 20816269 and 22829367. Compare both the replacement number and physical connection layout because similar-looking reservoirs may use different mounting points, hose connections or sensor 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.
