    Miracle in a bottle for Timing Chain tensioner?

    Hi everyone, new here (I've been reading for a while and finally registered:) and I have a question about an oil treatment that is supposed to help clear the ports on the hydraulic timing chain tensioner. My 2003 Sport Trac (XLT, 4WD, 4.0L SOHC) has 231k miles on it, and has been running smooth...

    Serpentine belt, tighten tensioner pulley

    For #reasons I've replaced the alternator in my 1999 Explorer. Not only is it the first Ford I've had since my 1978 Ford Econoline, but it's my first alternator replacement. Yay for me. I've done enough work on vehicles that I neglected to look up instructions before I started work and didn't...

    Stalling when in Gear along with Flickering Lights

    I have a 2006 Mercury Mountaineer 4.6 V8. It starts but stalls within a few seconds. I recently did a bunch of work to it (intake gaskets, valve cover gaskets, valve cover, vct sensor, crank sensor, etc) and now when I start it I hear a squealing/whining noise coming from the belt. I'm thinking...

    4.0 OHV Correct Belt Tensioner?

    Hey everyone. So it’s been a long time since I last replaced my tensioner and I really can’t remember what kind the ohv uses. I see Gates “round locator pin” and “v locator tab” on amazon, and both are listed as fitting my truck. I think I replaced it with the v tensioner last time but I’m not...

    Timing chain tensioner leak

    I replaced the left head timing chain tensioner on my Sport Trac, but I didn't realize that it was not threading into the head straight. I removed it and put it in straight with a new washer, and tightened it to the correct torque, my torque wrench could easily be out of calibration, because...

    2006 Explorer 4.6 Timing Guides

    I've got a 06 Ford Explorer 4.6 with the tow package that has around 133k on it. I bought the vehicle a couple of weeks ago and have no idea of its history. My question is would it be good medicine to replace the timing chain, timing guides, and tensioners while I do all the regular maintenance...

    2004 4.6L V8 - Belt Slipping Laterally

    (( In case anyone asks, this truck has seen 165k+ miles, primarily around the New Jersey coastline where it is really wet & salty. Hence he surface corrosion on nearly everything and the quarter panel )) Originally I replaced this idle pulley yesterday, which had been stuck long enough to...

    Idler came loose. Can't replace serpentine

    I have a 5.0L AWD 97 Explorer. My serpentine had been making noise while idling for a while now. It came loose today and I went to replace it, and this is what I found where the idler should be. Whatever fastens it to the engine was gone and it was just hanging on a peg. Both it and the idler...

    4.0L Timing Chain Replacement

    Well it has come that time where I need to start doing some thinking about my vehicle. I'm at 105k right now, and I feel like I have crested that hill on reliability. So far all I have replaced is minor things (Fuel pressure sensor, wheel bearing, balljoints, ect.) Well now bigger things are...

    How common is it to have the timing chain rattle with an intact main tensioner?

    I just finished the front timing chains, plugs, and wires on my 2002 Explorer last night. I had the famous rattle from about 2,200 to 2,800 RPM and it started in January at about 128,000 miles. I fully expected to see the main chain flopping around and bits of plastic in the oil pan and...

    Squealing/Tensioner shaking?

    A few days ago I started getting a squealing noise coming from under the hood whenever I accelerated on my way to work. Later that day I looked at the belt but it appears fine, no cracks and all of the grooves are still there. I noticed some dry mud on one of the pulleys. I cleaned it off and...

    Returning squeal

    So, I have a squeal under the hood. I know I had posted about this previously, but I thought I had fixed it with the replacement of the water pump and belt. Now, after that, the squeal was gone for a few days, but it seems to come back. I replace the belt, squeal goes away, then returns. I've...

    Rattling/Tinging Noise

    I have a '99 XLS 4.0 and there is a rattling/tinging noise coming from somewhere around the serpentine belt tensioner. Not so much when it's idling but when I rev it, it is very noticeable. I thought it coulda been the tensioner itself cuz it looks rather wobbly, but when I removed the belt and...

    Brand new serpentine belt has started squeaking

    I know what you're thinking already. This is some noob who thinks his belt is squeaking when really one of his components is. That's not it, though. Without the belt, the noise disappears. The full story: a couple months ago, the belt tensioner went bad really fast on my '97 V8 AWD Ex. I...
