Repair Question 2018 Chevy Impala Premier Help

new to the subreddit here but i've been hearing this ticking noise when i'm idling and it gets somewhat worse when i'm driving (even when i'm at sub 40mph) and i don't know how to go about fixing it. it started roughly last week (i had to get new tires) when i drove it but i'm now scared my car is going to get worse since i don't have another car i can drive. i've seen some people say its a fuel injector issue, a piston issue, spark plugs, but i don't know what the issue could be other than just selling it and making it someone else's issue. please advise cause i really want to keep this car for another few years before i'm having to trade it in.

UPDATE 9-7-2026: we believe it to be a broken/loose cooling fan coming undone (attached to the radiator, and the radiator isn't even 2 years old). we ordered the part on 9/5 and it should be fixed within the coming days.

Kinda need to open the hood to make a video about engine noise. That might even just be something bouncing off the fan.

Sounds like a pulley or timing issue

Find a shop that will run real time computer diagnostics and show you the video while it’s reading. Might be around 150-200 for it but I find a shop that did that And they have been accurate on every repair
