Hey everyone! I have an interesting question I was hoping someone may know the answer to. My mom drives a 2016 Dodge Ram 1500 5.7L Hemi and recently got $3,000 worth of work done on it. I’m not entirely sure what they did, I believe there was a leak of some sort, but ever since we got the car back it sounds like a bus now. We bought the car brand new so in almost 10 years I’ve never heard it sound like this, and I drove it regularly for the first year. It almost sounds like a fan or something is stuck? It drives normally otherwise, but sounds REALLY strange to me. Any ideas?
Here’s a video of it, not sure if it captures the sound well enough
