2020 Lexus ES 300h Service and Repair Manual
Every specification in this 2020 Lexus ES 300h service and repair manual is tied to one exact year, engine and trim — the 2.5L four-cylinder hybrid (A25A-FXS) and the trim your car was built as — so the torque values and procedures you follow are the ones Lexus published for this car, not a neighboring model year's numbers standing in for them.

Known issues on the 2020 ES 300h. One recall is on federal record for this model year, and it covers the engine and engine cooling: porosity in the engine castings may result in cracks that can allow coolant to leak internally and/or externally. A coolant leak can cause the engine to overheat and cause a vehicle stall in conventional gasoline vehicles, increasing the risk of a crash, and on all involved vehicles the engine may get damaged mechanically, possibly resulting in an engine oil leak, increasing the risk of a fire. Owners have filed 1 complaint for the year. The diagnostic and repair procedures behind the engine and its cooling system are here.
From tracing a coolant leak to a cooling system pressure check or a routine service interval, it keeps you on the OEM procedure and the correct specification for this 2020 ES 300h.
