Got about 137K on this beast; so far I’ve only had to put in a new radiator ($435, ack…) but has chronic growl when idling. Noticed similar symptom on other GC I drove for flower delivery. Can live with it but any advice/thoughts/two+ centavo$ appreciated. T’anks, Brian

I’m thinking either exhaust leak, or engine pinging.

Could be power steering pump or some other device driven by the serpentine belt. If you take off the belt you can feel for roughness or play in the driven devices. Also drive a short distance (avoid overheating) and see if the noise persists or has gone away.
