I was wondering, how to clean the radiator itself. The lower front side is clogged with dirt and grease. Should i use any cleaning solutions to get it off or wire brush or something?
At the autoparts store, such as NAPA, Autozone, Advance Auto, etc., there is a section with odds and ends repair pieces such as window cranks, drain plugs, body clips, nuts, bolts, radio knobs, and just about every thing you can think of that breaks or snaps off your car. These parts are on red cards that say "Help" in big white letters. They cover just about every car made, so you really need to be sure of what your are getting. Grease has saved you at least 30 minutes research by providing the part number you need.
Don't use anything stiffer than a nylon brush to clean your radiator, it is only soldered together and the fins are fairly fragile. To clean grease, the best option is to use a strong solution of dishwashing liquid. Mix it up in a bucket and get in there with your nylon brush. A strong jet from your garden hose will do well for rinsing.
