More likelier the coolant reservoir tank dripping.
Take a drive,pop the hood and wait for it
That makes a lot of sense because the noise seems to be a bit louder on the passenger side of the car. I'll go out tomorrow and have a look. Would the coolant reservoir drip naturally or would that indicate a leak? Coolant level and temps seem OK so not a major leak if so.
I took the car out for a 1 hr drive today after verifying coolant level was good. I did not use AC. Popped the hood when I got home to see if I could see anything from above but unfortunately I couldn't. I checked everywhere with a flashlight. It's more of a loud drip noise than a sizzle. The sizzle noise seems to be more prominent when I run the AC.
I won't have the ability to lift the car for a few more days to check from underneath but I'll report back once I do.
