Product Details
✓FITMENT FOR TOYOTA HIGHLANDER:For Toyota Highlander 2008-2013 3.5L V6 Gas; 2009-2013 2.7L I4 Gas; 2008-2010 3.3L V6 Full Hybrid; 2011-2013 3.5L V6 Full Hybrid. All listed engines are naturally aspirated. Engine and powertrain availability varies by year, so verify the exact year, engine, hybrid status and original reservoir before ordering.
✓NON-PRESSURIZED 0.65 L CONFIGURATION:This is a non-pressurized coolant recovery reservoir with a closure cap. The 0.65 L capacity is measured at the MAX fill level rather than the brim, leaving space for coolant entering the reservoir as temperature changes. The reservoir cap does not regulate cooling-system pressure; pressure control remains with the vehicle’s radiator or pressure-cap system.
✓HDPE CONSTRUCTION:The white HDPE reservoir is rated from -20°C to 110°C for the listed application. Its molded shape supports the required mounting position, hose routing and coolant recovery function. This configuration does not provide a coolant-level sensor function. Compare the tank shape, fill markings, hose connection and mounting points with the original part before ordering.
✓REPLACEMENT REFERENCES:Cross-references 603-289, 603289 and 164700P060. Match both the replacement number and physical configuration because similar Toyota Highlander reservoirs may use different hose locations, mounting points or cooling-system arrangements.
✓BUILT AROUND REAL REPLACEMENT NEEDS:Cracks, hose-connection seepage, dried coolant residue, repeated coolant top-offs or coolant discharged around the reservoir may indicate deterioration of the original bottle or recovery hose. BDFHYK treats this tank as part of the coolant recovery circuit: reservoir condition, hose routing, cap fit, fill level and radiator-cap operation all affect coolant movement. Continued coolant loss or elevated engine temperature requires complete cooling-system diagnosis.
