Thanks guys.
I am posting a lot now as I am still going over the pictures and jobs I did over the last 2 months, but soon I will catch up to current status and slow down
As I mentioned in the beginning, my rear tyres were OK-ish with thread, but they were coming from 2011. In the front I have 2020 Michelins and these are fine but I replaced the rear ones. In current situation with rising prices and decreasing availability of anything, if I exclude Chinese brands I could decide only between Conti and Pirelli. Nothing else was available here in the GS size. And I personally don´t like Continental (I understand they are great tyres, I just irrationally don´t like the brand) I went with Pirellis. And taking 2 wheels to my friends workshop to replace tyres, I took all 4 to have them re-balanced as well. And clean all properly.
Removing the tyres and having a good look, I found out the rims were resprayed. And sprayed with tyres on, just masking tyres and spraying rim faces. There is a lip and light paint peel where rim meets the tyres. No big deal, the job is nice and maybe over the next winter I am thinking to do the job properly and spray them inside-out in Grigio Mercury that I like on yellow GS more. More importantly I checked if they are straight and indeed they are. 2 wheels have a small hit, but nothing really bad and will be straitened in the future if I respray them.
The cabin filter was probably the last filter to replace.
It is hiding under the black cover under the windshield. The most difficult part is to remove the wipers, that´s usual pain and you need a puller to do so, but the rest is easy.
I was welcomed with a pretty dirty area full of leaves and dirt:
The black plastic over the air intake where you see a lot of leaves is actually glued on. Maybe it was leaking, I don´t know but somebody put a lot of black body glue to put it on. Structural glue, very difficult to remove, like windshield glue. I think if I ever really need to remove it, it will for sure break. So I only vacuumed all loose bits as good as I could and spend a over a good hour to clean all the area. I removed the wiper mechanism as well to make room and to clean that one as well:
Filter itself hides under the steel cover in the middle and just pulls out after removing the cover:
For the first replacement I bought OEM filter including the plastic frame as I didn't know what condition to expect, but I understand the filter is identical with Alfa 166 and you can replace only the paper filter inside of the frame.
Filter was pretty dirty, but not a disaster, I have seen worse on used cars:
Cleaned and assembled back:
I did clean and grease the wiper mechanism as well
And job done, except the final cover. As that one was really faded and more grey than black, I later restored it with ceramic coat. Came out nicely, but I don´t have a picture. Anyway, treating some small stonechips, paint clay, full car polish and ceramic coat is on the to-do list for the next 2 months.
