Aux. radiator clean

[mojoe]

Just bourght a B7 RS4. Was wondering how to go about cleaning the aux. radiators,of leaves and muck,before they start to corrode.
Do you have to remove the bumper,or can you access from underneath the car ?

Just pull the grills out of the Bumper to get to them, they are most prone to fail from the front in this area

I did this last week....can’t for the life of me get my NS grill to clip back in place!!

Had a quick look,through the grills. One looks bone dry,but the other one as water around it,and smells of anti-freeze. But water level in expansion tank,hasn't dropped by much. Both sides are free of muck though.
Am going on a weekend break to Wales,soon so hope it doesn't get any worse.

Mine has been like that for a year (slight dampness) and only now started to get worse . Have done just shy of 6k miles in that time . Driver's side so thinking of just removing it entirely .
