My friend just got a 2000 Mercury Cougar V6, mileage not disclosed to me. He's already asked my help to work on it. Both of us are mechanically inclined. He wants a reliable daily driver, nothing special or wild. He wants to do the struts all around. I'm also trying to sell him on new plugs/wires, transmission oil, PCV valve, and a new drive belt. What are other issues with the Contour platform and the Duratec 2.5l V6 I should know about before getting my hands dirty?
