This afternoon I was trying to take a look at the inside of the engine compartment. I could see the intercooler and didnít like what I found.
It looks to me like the paint/coating is flaking off and plugging some of the passages.
Has anyone seen this before?
That is just an extreme accumulation of road junk. Time to clean it thoroughly. There is a special version of SimpleGreen for aluminum that is recommended. Rinse, spray on SimpleGreen, rinse, repeat - or take it to a shop and let them clean it.
