2002 Ford Ranger Edge 3.0L V6 "clanking" sound

Joined: Jul 26, 2005 Posts: 18

I have a 2002 Ford Ranger 3.0L V6 and was wondering if you guys could help me with something. It's not a real serious issue...... yet. I've heard this sound on the road before with other cars and it's not real loud on mine. Usually occurs when I'm going up-hill and the engine is working a little harder. The noise kind of sounds like there are bottle caps bouncing around under my hood, almost like it's coming from the pulleys near the belt or something. It's a metallic sound but isn't real loud and is really only noticeable up-hill. I know it's pretty hard to give me an idea of what it is seeing the fact that I guess that you would have to hear it to know. I just know it's a distinctive sound that I have heard other cars making before. I do appreaciate the help though!!!!! Thanks!

You're kidding right? OK, I'll bite. I have the exact same model. During the
summer, when pulling up a hill on warm days, I get that sound too. What it
is is pre-ignition or spark knock. A little is normal and nothing to worry
about. If it becomes very loud, causes the truck to vibrate noticeably or if
it occurs when cruising on level ground, it needs to be looked at. Go to
the local Costco/Sam's Club and pick up a 4 pack of Chevron's Fuel Injector
Cleaner. Here in the PRK it will run you $9.00 and change for four bottles
verses $10.00 for one bottle at your local auto parts store. Follow the
directions on the bottle and see if things improve slightly. Odds are they
will. At 3+ years since purchase you might have maybe 40K on the clock
already. I know I have just shy of 48K. There is bound to be some carbon
build up in the motor by now, especially on the plugs. This stuff will clean
it out pretty well.
