After reading all the replies I have to say you are getting some good advice regarding dirty radiator fins (external). This is part of having a rear facing radiator. The Simple Green Extreme is a good start. Not distorting the radiator fins is a must.
Getting in there to get things cleaned up gives new meaning to getting into your work. If you are capable it is better if you do this yourself. If you pay most shops the big bucks to do it you will be going back all the time. It is not a fun job and a lot of people assigned the job are not going to apply the needed effort to do it well.

Radiator, charge air cooler, ac condenser and maybe an engine oil cooler. All making the job a bit more involved.
