    140k miles. I changed my spark plugs and wires on my 4.0L 2010. It seems to have started after that. I did have to pull my alternator to get the wires routed. I tried carefully spraying wd40 on the bearing part of each pulley. Then sprayed the pulleys with carb cleaner. Replaced the belt...

    97 4.0 SOHC - Spark Plug Replacement

    I just bought this 97 XLT a few months back, and it's in amazing shape for the age—just about everything works, and the body is rust-free! I don't know the maintenance history, other than it's had a lot of dealership work, but I figured it's always a good idea to do plugs/wires, like I've done...

    1999 Ford Explorer Tune-Up: 4.0 V6 SOHV

    I found out firsthand today why tune-ups are so expensive. On the 1999 Explorer with the 4.0L V6 SOHV, the plugs are a bit of a pain to get to, especially on the passenger's side of the engine. I have a Haynes manual for my vehicle; I found it was vague on what would be involved to change the...

    Seafoam. Yes or no?

    I'm thinking about adding Seafoam to my 2000 4.0 OHV and was wondering how safe it is. Also what's the best way to add it? I've read that you shouldn't add it to the oil, others say to add it to the oil but to change it afterward. The manufacturer says this is the best way...
