I was mudding last weekend and now my adiator was covered with mud. I already tried to clean it with a pressure washer, but it seems like there is still mud and dirt on and in it.
On the highway the temperature is about 10 degrees higher than before and I need to turn on the heating to come down to a normal temperature.
How can I clean the radiator? Is there a special trick to do that?
Do I have to soak the radiator for a while to get all mud out of it?
Thanks for your help.
