Get a little propane torch, put some heat on the block plugs. Several heat and cooldown sessions to help loosen any “environmental locktite” that may be there.

Thanks for tip , i should have that in mind
Finally i got the left side flap done and this is
also made of 3mm polycarbonate plastic.

That will help greatly, good work!

Clearance is needed between the shield and the radiator core to prevent abrasion that could wear through the radiator tube(s) over time. The clearance may already exist, I can't tell from the picture.

Hi thanks yes there is a clearence between plastic flap and radiator tubes , about 1/4". The
plastic flaps on both sides are resting on the vertical alu ridge so i don't think there are any chance the flaps will have any contact with the tubes.
I saw they have the waterwetter here also so i maybe buy a bottle in the spring. Should flush the cooling system more but we have had a lot of rain last weeks so i wait a little.
Very nice to have this forum and could get help and tip about our cars
