Hello all. I'm a new Lexus owner and know nothing about cars so please bare with me. I have a 2009 Lexus is350 with 98K miles.

I'm hearing a light ticking noise from the engine that comes and goes. It's not related to direct injection because the ticking is very soft, I first heard it last week while stopped at a light, but it eventually went away. I heard it again today as I was parking the car on the driveway. You can hear it inside and outside the car.

Here's a video of the sound:

The last maintenance done was a month ago
- Spark plugs replaced
- Transmission fluid changed
- Oil and filter changed
- Brake pads and rotors replaced

My initial guess was the water pump? According to the vehicle records, water pump was replaced in 2015 at 75K miles. But what do you think?

Also, I might be wrong but I think the ticking only starts after driving the car aggressively. Like today I drove through some hills and windy roads. I did something similar last week when I first noticed the noise. During my daily commute to work however I don't hear it at all.

Try a new OEM accessory belt. I actually had a similar chirping from my IS350 and installing a new OEM belt fixed it!
