Hey guys, I tried to search for someone with this problem, but apparently I'm the only idiot.

I was completing the serpentine belt replacement DIY (also replaced both idler pulleys, tensioner). In the DIY, it instructs to remove the (2) T30 torx screws holding the front intake duct in place and pull it back enough to access the tensioner and serpentine belt.

I'm afraid that I pulled back too hard on the intake duct and it may have slipped off (or may not be completely on) the front of the turbo. However, it's impossible to see down there, nor am I able to see it by removing the belly pan under the car. I tried reaching down but there are coolant and other lines that the intake duct slips behind; I can't feel if it is mounted to the turbo or see it.

What's the easiest way to access the front turbo to ensure that the intake duct is properly connected to the turbo? Is it possible to see it or reach it from the passengers side wheel well? Am I wrong and it can be reached from in the engine bay or under the car? Thanks for any help; yes, I realize this is a noob question.

Best way is to remove the radiator fan. 1 screw on top, one on bottom (only if automatic), disconnect the electrical plug, pulls straight up and out.

Then you have access to the front turbo inlet connection.

Remove the bracket holding the 2 vacuum tanks and you should see if the front inlet slipped off. Then you could use a persuasion tool to help you get it back on.

Would it be best to do this for the belt/pulley maintenance anyway?? Not to hijack, but curious as I just rolled 90k and have intermittent noise I believe to be belt/pulley combo...

If doing belt/pulleys, pulling the radiator fan is pretty much a must

Thank you guys for the replies. I did take the radiator fan out to complete the pulleys and belt replacement. I was able to get the inlet duct MOSTLY back on the turbo. There is an o-ring of sorts that has "ribs" on it for lack of a better term; I got it over the first two ribs but it absolutely won't budge any further. It feels like it's running better, though, and the thing that pointed to it possibly being incorrect (oil running temperature when warm of about 8-10F difference) has remedied itself so I feel good about it.

Thanks again for help MMPerformance and MPoster!

oh man! I'm so glad you made this post. I also changed the serpentine belt and pulleys and ever since have been chasing a turbo siren noise. I thought it was alternator noise initially and finally accepted that the noise could be coming from the turbos. I also pulled back on that front inlet perhaps a little too much in order to get better access to the belt and pulley and probably slightly disconnected the front inlet. I'm so glad you made this post as it has made me so much more confidant that that is my solution as well. I will remove the vacuum canister to get that connection back on probably today. thanks for posting back your results. I will do the same. I want that turbo siren noise gone once and for all as it is driving me nuts. peace!

Reporting back: the front inlet was secure that was not the cause of the my siren sound. Still trying to figure this out
