1.8L Serpentine Belt Tensioner

[Dalm]

Okay so I can find a decent amount of info on the 1.4l tensioner, and those are the kind I am used to dealing with. Haven't seen one that looks like the one in the 1.8l, and on csmans they only show the 1.4l tensioner in the guides.

I have a tensioner that looks like this :

My question is do I need to turn the bolt in the center of the belt pulley or the 12-point? It also looks like I need to turn it counter-clockwise in order to relieve tension, so i'm leaning toward turning the 12-point casted part. Anyone else done this and know what size wrench and can clarify which one I should turn?

This is what my tensioner looks like from below with the belt still on the vehicle, not a lot of clearance here.

And from above:

Im gonna be doing my compressor but want to make sure I have the proper tools before I pull the engine mount off as I definitely dont have a torx socket if I need to undo that bolt or turn it in any way, though I believe this is just the mounting bolt from looking at the part on amazon and such.

Thanks,
Dalm.

Thanks but this vehicle uses a different type of tensioner. I guess this particular cruze doesnt use the 1.8l, and I haven't been able to find a video/repair manual that documents the 1.8l tensioner.

I'm very jealous of the amount of clearance this cruze has, my buddy with the 1.8l cruze has a similarly tiny amount of clearance as my sonic.

Just an update for anyone doing work on this tensioner/beltline; If you aren't replacing the belt you probably dont need to remove the motor mount, I was able to relieve the tension using a 19mm 12-point socket on the cast nut and slip the belt off for me to get the compressor removed and replaced. Turn the nut counter-clockwise to relieve tension, I was also able to stick an allen key in the locking pin hole but cannot remember what size I used.

The clearance really sucks but its doable if you have small enough hands and arms, otherwise you may want to use a special belt tool that has the flat arm in order to fit in small places.
