Before hot sommer need to clean, at least try to do it as much as possible.
Between intercooler and main radiator there was lot of leaves and other herbal composition. And no acess at all, 2mm space only.
Well, again, like McGiver need to invent special tools and just try.
Leaves I get out mecanicaly.
Other ... soap water, pressured air, water flow and some selfmade tools helps.
And of course hidden radiator behind fog light.

(Edit, I'll shut up, the following is for the 405 not the 322.... dooh....!!)


There is info in the handbook on how to help clean the rads…
