Engine whistling when coasting/slowing down
This may sound weird, but I can hear a slight whistle :whistling: when my 13 JKUR is slowing down. Could it be a leak?

Mine whistles during acceleration, around 2k rpms. Searched high and low with no luck!! Checked vacuum lines around battery box, no success in finding anything out of the norm. 07 jk

1000 miles so far. Thought I would do a quick check here first. Thanks!

Mine does the same thing. It whistles as you decelerate. I took it to the dealer and they replaced the water pump and flushed the lines but it did nothing to help. No idea what the problem is
