Timing Tensioner Problems of Ford Explorer
Ford Explorer owners have reported 40 problems linked to timing tensioner (under the engine and engine cooling category).
#1 - Timing Tensioner problem of the 1998 Ford Explorer
The vehicle involved is a 1998 Ford Explorer. The vehicle identification number (VIN) is 1FMZU34E8W_. The timing chain tensioner broke allowing the chain to slip. It was a recall problem but I was not the original owner and the problem must not have been addressed, or else the recall didn't get done properly. After the repair it hasn't had good oil pressure at idle. It is too bad that Ford put this motor in so many vehicles and doesn't stand behind they. It is poor design in my opinion to have four timing chains on a 4. 0 liter motor is crazy. I wish that Ford would have put more effort into seeing that my vehicle were recalled and not allowed to depreciate because it was happening to so many other Explorer. This timing tensioner problem happened on 01/15/2013.

#4 - Timing Tensioner problem of the 2003 Ford Explorer
The car was a 2003 Ford Explorer. Timing chain broke, with no warning, bent all the valves and wasnt even driving it. Had just started the car in the garage and backed out of driveway with car idling very rough. Pulled back in driveway and oil was pouring out underneath, due to chain had busted the valve cover. Well had to pull the motor, replaced guides, cassettes, and tensioners, with 2000. 00 just in parts alone. Had car back from mechanic not even 3 weeks and engine started knocking as if a rod was knocking. Went back to mechanic and tensioners were the cause of timing-chain "clank". Apparantly they (Ford) designed these tensioners with "plastic" guides which shred off into the hydraulic tensioner pick up tube therefore clogging up the hole for oil to get to chain and will continue to do so unless you get updated tensioners directly from Ford at 100. 00 each. There are 3 timing chains and multiple tensioners as well, which continue to go out after 30,000 miles and need replacing, which most can be replaced with motor in but some cant therefore I have had motor out twice now, at 2500. 00 each time. There was an onp to owners but Ford would only cover cost up to 100,000 miles and only if owners complained!! otherwise they would not fix!!! well this is a bad design on Fords part with plastice tensioners to guide your timing chain!!! now they have updated with a tougher nylon "plastic". But have not recalled the old ones so unless you order dealer parts you receive the old parts which are no good and will end up making you spend more money and for the last 12months, I have had my car 3 weeks due to cant afford the enormous repair bill, which Ford knew about all along, but failed to recall plastic parts unless someone complained. According to my research it has been an ongoing problem since the 1996-2006 year model explores with 4. 0 sohc v-6 motors. Something definitely needs to be done!!!. It was Tuesday, February 1, 2011 when this timing tensioner issue happened.
#5 - Timing Tensioner problem of the 2003 Ford Explorer
The vehicle is a 2003 Ford Explorer. The vehicle identification number (VIN) of the car was 1FMZU73K33_. Timing chain tensioner failure with valve cover damage provoking oil leak and heavy smoke out of the engine, wich lead to spill of oil in the highway (oil dropping) and engine out of sequence due to a plastic "casset" tension break, I have read over the internet alot of complains about the same incident. This issue happened on Aug. 15, 2011.
#6 - Timing Tensioner problem of the 2003 Ford Explorer
Vehicle failure problems with 2003 Ford Explorer. While driving the vehicle stalled in an intersection. The vehicle was taken to the dealer where it was determined that there was sludge in the engine. The dealer insisted that the consumer's neglect was the caused of the failure and if he refused to purchase a new engine from them they would void manufacturers and extended warranty. The consumer indicated that he took care of his vehicle performing all the regularly scheduled maintenance. The consumer believes this problem is related to a defect in the timing chain tensioner. This issue happened on February 16, 2004.
#7 - Timing Tensioner problem of the 2002 Ford Explorer
2002 Ford Explorer with a v6 engine, purchased new, maintained, has 77,000 miles. While driving vehicle it became erratic, as if water in tank, drove about 1/2 mile when it died. Now the engine needs to be replaced: according to warranty inspector the "cassette failed due to the hydraulic tensioner and it is clogged with sludge, sludge is getting thicker and it has clogged a pin hole in the tensioner and caused a loss of pressure". Geico will not cover the engine replacement because they claim it was caused by lack of maintenance; however, I provided them with records of the mileage and date of oil changes at intervals between 3k and 5k miles, problem I have receipts for only 75% of those changes. The highest gap between a receipt backed change and non receipt change is 7000 miles. This problem seems awfully similar to the 1996 - 2002 Toyota camry engines. I think Ford has a lot of explaining to do. Previously, this SUV had to have a transmission replaced at 50k miles and a rear differential at 65k miles, thank goodness they were covered by the warranty. It was Monday, February 20, 2006 when this timing tensioner issue occurred.
#8 - Timing Tensioner problem of the 2002 Ford Explorer
I just bought a 2002 Ford Explorer with 74,000 miles on it. I have had it for just long enough to discover a few problems with it, and have done enough research to know that I am not the only one by far with the same problems. I am not sure what causes the problems that I am experiencing, I just know that lots of other people are also having these problems. First of all, there is a leak in my rear differential. My truck is currently in the shop for that now - however, the shop mgr refuses to fix the leak until the rear end breaks. . . . Which will cost more and cause more repairs than necessary at the current time. My second problem - which the service mgr again refuses to fix until it breaks is with the timing chain tensioner - which leads to transmission problems which are also very costly. I have done my homework on this situation, since I have been forced to, and I am seeing over and over and over again, replaced the rear end on my 2002 Explorer (multiple times on the same vehicle), and I am seeing over and over and over again, new transmission on my 2002 Explorer (again, multiple times on the same vehicle). I don't know if anyone else knows about this site, or I'm sure that hundreds of the same kind of complaints would be filed with you. . . . Someone really needs to look in to this problem, because Ford is awful proud of their vehicles and I am paying a hefty chunk of money for mine, as are the tons of other people out there with the same problems who just may not know how to go about getting something done regarding this problem. . . I'm speaking not only for myself, but, for loads of other people with the same problems. Please look into this problem, I beg you!! I don't want to be on the side of the road with my babies (4 & 5 yrs old) praying that the right person stops to help me and not the one with bad intentions!! something needs to be done about this - Ford has got obvious drive train problems!!! thank you for your attention in this matter!. This problem occurred on 07/06/06.
#9 - Timing Tensioner problem of the 2002 Ford Explorer
The car involved is a 2002 Ford Explorer. I have two or three issues; the first one is my timing chain tensioner broke and came up through the head gasket cover. It was brought to my attention that Ford has had this problem with many of it's 2002 Ford Explorers. I am just returning from iraq (air force) I have just had it towed to the repair shop it has not be fixed. I have transmission problems for about 2 years were it jumps into gear and I have a whining noise coming from the rear end. I spoke with ganley Ford in barbeton and they tell me that there are no recalls however, a lot of customers complain. This timing tensioner issue occurred Feb. 3, 2007.
#10 - Timing Tensioner problem of the 2002 Ford Explorer
My wife's 2002 Ford Explorer had a whine in the rear end since it was new and it continued to get worse with time. At about 55k miles it was so bad that we had to have the entire differential rebuilt at a cost of over $1,000. At 65k miles the engine had begun to make noise and it became much louder rapidly. The entire cam drive (timing chain, sprockets, tensioners) had been ground up. The tensioner pads had 3/8" deep grooves worn into them and there were metal shavings everywhere. The bill this time was almost $1,300. It is interesting that all the parts that were replaced were a different design than the originals. If there was nothing wrong with the original design, why spend the money to change them? of course Ford would not admit that they had a problem with the timing chain for the cams. After the timing chain was fixed there was still a noise so we took it back to the shop that did the work. With a stethoscope the noise was isolated to the bellhousing/torque converter area. We took it to a transmission shop we trust and he thought it was a cracked flex plate because that happens frequently on these vehicles and it causes that kind of noise. The flex plate was fine as was the front pump on the transmission and the starter drive. The only thing left in that area was the torque converter so we replaced that. The noise was still there. He said that the noise had to be coming from the transmission and that would be a $2,000 repair. I've had it with Ford and their "quality is job one" or whatever their current advertising lie is. This car is a lemon and they won't admit to a single thing being wrong with it. Every driveline component has had to be fixed and it only has 67k miles on it. Ford should be ashamed of the way they hang their customers out to dry. Even though I had to identify a particular date below, this car has had major problems since it was new in 2002. It was 07/14/2008 when this timing tensioner issue occurred.
#11 - Timing Tensioner problem of the 2002 Ford Explorer
Timing chain rattle on a 2002 Ford Explorer. Had the fronts replaced once under warranty at about 25,000 miles and again at 80,000 miles at my expense. Now the rear chain is making noise, this is after having the rear tensioner replaced last month at 94,000 miles. The rear cassette seems as if it is ready to go. I don't know how Ford can get away with producing such a poor product. There a thousands of complaints about this problem and Ford won't do a thing about it. The failure date was Mar. 8, 2009.
#12 - Timing Tensioner problem of the 2001 Ford Explorer
The car is a 2001 Ford Explorer. While driving engine check light will flash intermittently. Dealer has been notified.

Camshaft tensioner replaced under recall shortly after, mechanic said this would eliminate noise. Noise grew progressively worse over time - brought into a Ford dealer, had veh. For a week and replaced front cam chain guide. Went to p/u vehicle and was informed noise is still there due to rear cam chain guide needing replacement. Would have to pull motor for about another $1000. Two independent mechanics informed me both guides failing due to cam shaft tensioner. Both guides would not fail at same time on opposite ends of motor unless joined by common part. Dealer and Ford motor CO. Basically said that's my problem. This issue happened on Mon., May. 1, 2000.

Was directed by dealer that ther was no other fix for problem but would not cause damage. Was told that if part failed Ford would warranty for 5 yrs or 75,000 miles. Part failed causing timing chain to slip and break, causing #6 cylinder piston to strike valve and put hole in piston. Ford now states that they are not responsable and will provide no relief for repair. Ford dealer advises that should have been covered but Ford makes final decision. Ford's final position is that age/mileage of vehicle problem is now my problem. Vehicle is 1999 Explorer with 60,000 miles which meets both of their cryteria in their service bulletin.

#22 - Timing Tensioner problem of the 1998 Ford Explorer
The vehicle is a 1998 Ford Explorer. Very heavy rattling in the engine of my 1998 Explorer 4. 0 sohc. Took to local Ford dealer, they claimed characteristics of the motor, twice. Some time later tensioners broke while driving and motor ceased. No cooperation offered on Ford's part. Had to replace engine out of pocket for Ford's design flaw, which has been getting swept under the rug for years now. One month after the replacement Ford offered to fix others, if found before 75k miles, etc. Too late for me. How many failures have occurred? what if this failure had of occurred at highway speed, instead of idle speed. Check the figures on this problem, it's scary, and Ford is pitiful. This problem occurred on Nov. 26, 2004.

The vehicle is a 1997 Ford Explorer. The VIN of the problem Explorer is 1FMDU34EXV_. Chain tensioners have deteriorated and broken up. Engine now rattels and grinds. I have fear of major engine damage. After talking to Ford dealers in reno nv and one in susanville CA I have been told every thing from "your on your own " to " Ford is working on a permanant fix so be patient. Is Ford going to fix my problem . I understand this to be a major widespread problem.
#26 - Timing Tensioner problem of the 1997 Ford Explorer
The car involved was a 1997 Ford Explorer. The VIN of this vehicle was 1FMDU32E5V_. Engine- vehicle began making knocking/ticking noise from engine at 30000 miles, took into dealer to report it, and they said no problems. Noise was at start ups and after vehicle had set for brief time. Noise became louder and longer in duration, took back into dealer at 35000 miles, again, they said no problems-normal noise. At 41900 miles, vehicle became undriveable, noise was extremely loud and metallic in nature. Took to different dealer who stated that they had numerous problems with 1997/98 Explorers with 4. 0sohc engine timing chain tensioner failures. Most were under warranty and they sent entire engine back to manufacturer to repair. Now my vehicle was out of warranty and the reapai cost me $700. 00. The vehicle went back 3 days later with same problem, another $300. 00. I feel that I reported my problem while the vehicle was still in warranty and that Ford should cover the repairs. I also think thatford is fully aware of a widespread problem with these 4. 0 sohc engines and the timing chain/tensioner defects. I have talked with many dealers and individual owners who have stated the defect is not isolated. Had my family and I been traveling at high speed when this thing went bad and the engine quit,there could have been an accident. There needs to be a formal investigation into this issue, it is too widespread and Ford certainly is aware of the problem, but unwilling to address it and compensate consumers who are suffering with this. Fuel system- there is also a hesitation/stalling that occurs on same vehicle that has been into teh dealer on several occasions to fix, but can not be diagnosed or repaired. This is very dangerous especially when pulling into intersections or turning at traffice lights. My wife has had several near misses due to this. Again, this appears to be widespread with this 4. 0 sohc engine. Please let's have something done about this before someone is hurt. Ford's army of engineers surely are aware this exists. Mark ditto. It was 07/07/99 when this timing tensioner issue occurred.

I have had my Explorer in a local shop for 4 weeks "diagnosing" me check engine light problem.

I also found out today that I am going to have to purchase a new engine for the low, bargain basement price of $5400. My god that makes me happy. There are 4 Explorers in my local dealership with the same problem. I am beginning to see a trend here! could somebody please tell me what's up with these engines.
