only 4 bolts but hard to get to if you don't have miniature hands like me. haha. You can get to it if you can get someone with skinny arms/hands to get in there to turn a wrench. Just gotta move stuff (hoses, bpt valve, engine harness, etc) out of the way to get more room. I happened to get mine out to clean it but it was a pain and I have knuckle scars to show for it.
You can kind of see it here in the top right image; bottom right corner.
