This service and repair manual is built around the 2008 GS 350 specifically, covering the 3.5L V6 (2GR-FSE) in either AWD or RWD form, so the clearances and torque figures you work to are the ones Lexus published for this year rather than values carried over from an adjacent GS model year.

Known issues on the 2008 GS 350. Two recalls are on federal record for this model year, and both concern the engine. The first, filed under engine and engine cooling, traces to the valve springs: micro-foreign objects in the valve spring material, with the consequence that the engine could fail and stop suddenly while the vehicle is in motion. The second covers the variable valve timing hardware, where loose bolts could cause the VVT gear housing and sprocket to separate. Owners have filed 25 complaints for the year and Lexus has issued 59 technical service bulletins. The diagnostic and repair procedures behind each of those systems are here.
Whether you are inspecting valve springs, checking the VVT gear housing and sprocket, or working a scheduled service interval, it keeps you on the OEM procedure and the correct specification for your specific 2008 GS 350.
