Engine Coolant Recovery Reservoir
High-Efficiency Overflow Tank for 2001–2005 Toyota RAV4
Keep your engine cooling system performing at peak efficiency with this premium Engine Coolant Recovery Reservoir. Designed specifically for the second-generation Toyota RAV4, this non-pressurized expansion tank acts as a critical buffer for your radiator. As your engine reaches operating temperature, thermal expansion forces excess coolant into this reservoir; as the engine cools, the resulting vacuum draws the coolant back into the radiator.
After two decades of heat cycles, factory plastic tanks often become brittle, yellowed, or prone to hairline fractures. Replacing a cracked or leaking reservoir is essential to prevent air from entering the cooling system, which can lead to localized "hot spots" and catastrophic engine overheating. This replacement unit is manufactured from high-impact, heat-stabilized polymer to ensure a long service life in the harsh environment of your engine bay.

Installation and Technical Tips
Cold System Service: Never open the cooling system while the engine is hot. Wait for the vehicle to cool completely before removing hoses or the reservoir to avoid the risk of pressurized steam or scalding coolant.
Reuse Factory Hardware: This unit is designed to slide into the factory mounting bracket or bolt into the original locations. Retain your original mounting bolts during removal as they are not included with the replacement tank.
Hose Inspection: Check the overflow hose running from the radiator neck to the reservoir. If this hose is cracked or clogged with mineral deposits, the "recovery" function will fail, and your radiator will eventually run low on coolant.
Fluid Level Maintenance: After installation, fill the reservoir to the "Full" mark with the Toyota-recommended Pink or Red 50/50 pre-diluted coolant. Re-check the level after 24 hours of driving to account for any air that may have purged from the system.
