Where is the coolant pump B installed in the Leiling Hybrid?

Toyota Leiling's coolant is located at the lower hose of the radiator. The engine coolant in the Leiling provides the following protective functions: 1. It offers anti-corrosion protection for components of the cooling system. 2. It prevents scale buildup, avoiding a reduction in the radiator's heat dissipation efficiency. 3. It ensures the engine operates within the normal temperature range. Additional knowledge: Leiling coolant replacement method: 1. Unscrew the radiator cap, open the radiator drain valve, and drain the coolant. 2. Insert a rubber hose connected to a tap into the radiator filler port, turn on the tap, and allow tap water to continuously flow through the engine cooling system. During the flushing process, keep the engine idling and continue the operation until clear water flows out of the radiator. 3. Turn off the tap, wait until all water is drained from the cooling system, then close the radiator drain valve. 4. Add coolant into the radiator filler port until it is full. Unscrew the reservoir cap, add coolant up to the "Max" mark, being careful not to exceed it. 5. Replace and tighten the radiator cap and reservoir cap. 6. Start the engine and let it idle for 2-3 minutes, then unscrew the radiator cap. At this point, as some air is expelled from the cooling system, the coolant level will drop. Add more coolant until it reaches the "Max" mark. 7. Securely replace the radiator cap.
I've repaired quite a few Levin Hybrids, and that coolant pump B is usually installed in the left area of the engine compartment, near the firewall and the hybrid inverter module. As an experienced technician, I often check it there because this pump is part of an independent system specifically designed to cool the battery and electrical components. During maintenance, you can see it connected to coolant hoses and wiring when you open the hood; its location is chosen to be close to the core components for efficient heat dissipation. If it fails, it may cause the inverter to overheat and shut down, or even trigger fault codes in extreme weather. I recommend checking the pump for smooth operation or leaks every two years during routine maintenance to avoid costly repairs. Such additional pumps are critical in hybrid vehicles, and proper maintenance can enhance overall reliability and fuel efficiency.
