No, it has a timing chain.
The Lexus GS300 qualifies as a midsize sedan. This is a great car, and it has only improved with each new generation Lexus has released. Its latest design was in 2006; however, the 2006 model was discontinued after a year and then rereleased as the GS350. Lexus made the GS350 in a response to the consumer complaints about the lack of power in the GS300. The GS350 was released with a 3.5 Liter V6 engine. Both the GS300 and the GS350 are identical except for the beefed up engine. Hope this helps.

The Lexus GS350 typically has an engine oil capacity of approximately 6.4 quarts (or about 6 liters) when including the oil filter. It's always best to consult the owner's manual for the specific model year to confirm the exact capacity. Regular checks and changes are essential for optimal engine performance.
GS350 uses long-life transmission fluid which doesn't have to be replaced until 90,000 miles. Make sure to get it replaced at reputable Lexus dealer , since they have the equipment to flush the entire fluid, rather then just draining portion of it.

To turn off the maintenance light on a Lexus GS350, first, turn the ignition to the "ON" position without starting the engine. Next, press the gas pedal three times within five seconds. Finally, turn the ignition off, and when you restart the vehicle, the maintenance light should be reset. If the light remains on, you may need to check for any ongoing maintenance issues.
To replace the bulb on a 2007 Lexus GS350, first, open the hood and locate the back of the headlight assembly. Depending on the bulb type, you may need to remove the dust cover by twisting it off. Disconnect the power connector from the bulb, then twist the old bulb counterclockwise to remove it. Insert the new bulb, ensuring not to touch the glass with your fingers, reconnect the power connector, and replace the dust cover.
The following models are affected: 07-09 LS460 AND LS460L, 07-09 GS350 AND GS450H, 2008 GS460, 2008 LS600HL, 2006-2008 IS350.
Most Lexus models use timing belts, but several models, particularly those with the V6 and V8 engines, feature timing chains. Notably, the Lexus RX350, GS350, and IS350, which are equipped with the 3.5-liter V6 engine, have timing chains. Timing chains are generally considered more durable and require less maintenance compared to timing belts. Always refer to the specific model year and engine type for confirmation.
