nme 95k: I would like to say thanks! watched this video and followed to the T and 100% accurate. perfect video. on to video #2

Justin1k R: I've had the issue with the cold start rattle and the rattle above 2500rpm. Had primary tensioner in front replaced for 1800 bucks...noise went away but it is back. Should it go away if I replace the other two? what are the part numbers for the other two?

bleedingeyeball27: *****NOBODY CAN FIGURE THIS OUT!!!!I have a 2006 Lincoln Navigator a whirling sound from engine compartment. NOT POWER STEERING, but sounds like that when PS fluid gets low and wheel being turned. No check engine lights or rough idle. Running just fine...for now. Any help would be appreciated. I have a 24 sec video --

bfan64: My 1998 stopped entirely. The mechanic told me the 3 timing chains outside the engine were broken and they thought that it wasn't worth fixing. They said the entire engine had to be pulled to fix which would be very expensive. They said there is also a chain inside the engine which also might break so they recommended replacing engine. (which they don't do) Does this sound right?

Mmmmm Toast: Hi, what is the part number for the lower tensioner? I can find the 6k254a is the top one, but the ford diagram doesn't show the lower one with a part nubmer. Thanks

Matt Casdorph: I thought I'd ask this to make sure I know where these tensioners are, looking toward the motor from the grill area, is the short on on the passenger side on the head near the firewall? and the other on the driver side is toward the belt near the front end of the valve cover? I've never replaced timing chain tensioners before I'm assuming these are the ones since they look like the pictures of the tensioners. Our Explorer started making the rattling noise and I suspected the tensioners upon reading different things online. I would rather try replacing the tensioners since its cheaper to see if it fixes it before getting into checking the timing chain guides, I almost thought it may have been stuck valves but a buddy at the local garage used a stethoscope and came to the conclusion the noise was coming from the timing chain areas.

EDIT: never mind, had I watched the video before asking if those where the tensioner's, my answer was in the

JOSE BADBOYJOSE: hey guys I have a 96 Ford Explorer 4.0 which sometimes it gives me a problem on startup have noticed that I have low oil pressure sometimes but the truck runs just is that when I turn it off and try to start it back up it gives me a problem to start up sometimes could this be the timing belt tensioners

getredytagetredy: Drop the tensioner bolt in oil to lube it before fastening

GS Allen: This video saved my........nerves, engine, etc. Had been poring over the online forums for a couple years on the timing chain issue - never saw mention of this welcome fix. Replaced both and the engine went silent on the chains aspect. But after 2 days the front tensioner was making a loud grinding noise; so I put the old front one back in that seemed to have decent spring pressure. Now, after some 2000 miles, it starts quietly and runs quietly, with the injector percolating making the most noise. Had the chain noise problem for 5 years and was always worrying about a chain breaking and destroying the engine. Was always able to let it idle a minute or two until the chain noise went away. It appears these tensioners were the only problem. Got lucky, I guess. Now will keep the Explorer a good while longer.

qbce123: Hello I've replaced the tensioners and i still have the same rattle? It sounds exactly the same as when you turn your explorer on. It even rattles when its warm. Any ideas?

Michelle Francis: I have a 2001 explorer sport and my truck just started this crazy noise last night! I took the tire off and the bolt is not in the same spot! Any idea where they would be?

Logan Ferguson: My truck rattles at start and at 2500 RPM when cold.
Couldn't find where it'd been mentioned in the comments previously so here is my question;
When removing the tensioner, wouldn't slackening that timing chain cause the timing to jump if the valve springs are under any pressure? Do you have to set the motor to TDC prior to removing the tensioner? None of the videos mention this and my concern would be the timing jumping upon removal of the tensioner but it seems as though everyone does okay just pulling them out and putting new ones in? Is this not of concern because the tensioner is on the slack side of the chain?

Trevor Fisher: Just did this job on my son's 03 Sport Trac, last night.  It had slight rattling on cold start.  This did the trick and silenced it. Extremely happy with the result.  Thank you for posting this!

Randy Kirkman: here in orange county ca none of my part stores carried it ebay less than $20

Randy Kirkman: hey people also its a bitch to remove the entire thermo housing, but suggest you do, it was worth taking out, the seal was grungy. You don't want to take it all apart again for a bad seal and, replace the hard to get hoses w/real hose clamps F them factory clamps keep y'all posted

Randy Kirkman: been working on cars sense I was 11, 54 now.I build custom retro rods. What I want to know is WTF were these Germans drinking when they designed this engine.

trickydicky7383: Ideally you should have left the new tentioners to soak in warm oil for 12 hours before you installed them. Still a great installation video.

wbrudi28: Did you use ford OEM tensioners? I'm looking to do the same to mine, both left and right

drake7331: Should I use some kind of a gasket or something on the new tensioner? I took out the OEM tensioner and there was a metal gasket at the base of the tensioner. I added a rubber seal on the base of a new one and installed it in my car. The death rattle is pretty much gone, however, at cold start there's a really weird squeaky noise coming from the new tensioner. Why is that? When I used no seal/gasket, it leaked oil badly, so I don't know what to do now...

JESUS ROBERTO RAMIREZ HUERTA: hi guys I have a ford explorer mod 99 eddie Bahuer 4x4 and sometimes sounds like the chain of time but the strange thing is that sometimes takes away, I think that if some tensor'm not sure anyone can tell me your opinion about this. excellent video
