f@ck arse c@nt.
Yip, gave it a bloody good try, easy job to remove the air box & MAF.
Then had to either"
A) Take alternator off
II) Make a hole on the plastic trim.
I tried to take the alternator off but after taking the 2 bolts out I could not for the life of me budge it, neither could my father in law... when I pulled up I moved the engine

When I pushed down, I moved the car down...

How the f@ck do you get it off?!
So then I had enough of that, so made holes in the plastic trim covering the light housing so I could do it with the alternator on...
17mm spanner BENT, 3 hours trying different things to budge it including metal poles over the wrench and spanner for more leverage, hammers, mallets... it would not budge.
Then it started getting dark, so I put it all back together, washed my hands and put the kettle on.
143k miles makes the job so much harder.
Oh and and EASY way of moving the tensioner is a mole grip, set it to the right width to grip the nob on top, clamp it down and it's SO much easier to move the tensioner then, with a allen key locking it in place. It started out so well, got it stripped down really quick, just couldn't do the last 1/2
Many thanks to my father in law for helping out today while going back and forth cooking dinner too

oh and my daughter for getting under the car and feeling in the splash guard for the splined bit that goes over the shaft locking bit, that fell and disappeared into the midst of oil and sponge down in the depths of the splash guard, I owe ger a fiver now lol shouldn't have bet her she couldn't find it
