RX400h Posted November 17, 2023 Share Posted November 17, 2023 The bypass hose in a 2003 Lexus ES 300 is part of the vehicle’s cooling system. It plays a crucial role in the circulation of coolant. If your Lexus ES 300 has been either leaking coolant or overheating, you could have a faulty cooling system bypass line1. The bypass hose ensures that the coolant bypasses the radiator and flows directly into the engine, which allows the engine to reach its operating temperature more quickly. This is particularly useful in cold weather, as it helps the vehicle’s heater to warm up more quickly. If the bypass hose is damaged or malfunctioning, it could lead to issues with engine temperature regulation. It’s always recommended to replace a faulty coolant hose with a genuine Lexus part. So if your engine is leaking coolant at a rapid pace, you may not want to drive it to the dealership. Quote Link to comment Share on other sites More sharing options...
