The Lexus RX350 Coolant Reservoir protects engine health by holding excess coolant, then releasing it back once the temperature drops and makes the coolant loop full and air-free. Mounted inside an RX350 engine bay, the tough plastic unit connects to the radiator via a hose, allowing heated coolant to expand into the tank instead of spilling onto the ground, in a simple act that also keeps dangerous antifreeze away from the environment. Across RX350 model years, two main styles can be found. Non-pressurized overflow versions put the pressure cap on the radiator, use a light plastic lid on the Coolant Reservoir, and depend on the difference in pressure to force liquid out and vacuum it back. Pressurized expansion designs boast the ability to move the rated metal cap to the tank itself, meaning the Coolant Reservoir is now in the sealed system, is higher than the radiator, and is molded from stronger reinforced plastic to withstand full system pressure while making a permanent air space for thermal growth. Many Lexus drivers like the obvious level marks that allow for cold engine checks to be carried out, and every RX350 Coolant Reservoir adds to the Lexus cooling system that prevents rust, leaks, and overheating. This Coolant Reservoir advantage extends the life of the Lexus powertrain.
