i can't spary the intercooler... i think a pic of the engine bay might be useful.
careful, clicking on the image loads a 1MB image file for better viewing.
anywho... incase you are unsure, the reservoir has the "green liquid" in it.'' as u can see... sparying the intercooler itself is not really an option... but keeping the reservoir cool would be much easier and i think just as, if not more beneficial.
