Removing parts, I noticed there is the actuation sensor on the top plastic cover, removed it and removed the cover. How is the big piece which the sensor attaches to underneath the cover is removed? Just remove the star screws?

More then likely yes, you just remove the screws that are called torx screws but can you get a picture of what you are dealing with?

I suspect you have a 1.8L as if you have a chain that is the only 4 cylinder with a turbo that has a chain. The 2.0L should have a belt so I attached the complete process below on how to replace the chains on this vehicle.

Let us know what questions you have. Thanks

When inserting the long tool to push back the tensioner it doesn't budge, I believe it is out all the way, that is why am changing the chain. I checked it through the hole and saw it was at its limit and when the crank is on time both camshaft are couple of teeth out, so what do I do to remove the tensioner if I can't push it back?

So instead of putting the crank on time first and then having to move both camshafts later so they align should I align the camshafts and lock them then worry about the frank?

Yeah. That is what I normally do is lock the cams so that are held in place but if you think about it, once the engine is locked down and you remove the chain, it doesn't matter what position it is in as long as the chain goes back on without it moving. So if you align the cams or crank so that you can get the chain in the correct position and then the engine doesn't move until the new chain is installed, then the engine will remain in time.

A lot of people think they need to set the engine in time then remove the chain. That is fine but the engine is already in time so you just need an orientation point which would be the cam or crank and then you can lock it down and put the new chain on and it remains in the same position.

The only times you need to re-time the engine is when the chain skipped or broke or the engine moved when the chain was removed.

Hope that helps. Thanks

Yes, that is what is going on. It isn't time as I indicated in my previous message, otherwise I would have locked everything and it's easy.

You mean the timing chain guide tensioner? No, you can't put this in if it is not retracted or you will not be able to get the chain and guides on.

If you have a bench vice, you should be able to squeeze it and install the lock. Below is the locking info.

Oh. Sorry. Yes. If you are not putting it back on then it is fine to just take it off.
