What is the problem with the timing chain on a Ford Explorer?
The core issue is wear or failure of the timing chain, its tensioner, or guides in certain Explorer engines, which can let the camshaft fall out of sync with the crankshaft and cause timing-related engine problems.
Across several generations, Explorers have used different engines that rely on a timing chain rather than a belt. When components such as the chain, tensioner, or guides wear or fail, timing can drift, leading to symptoms ranging from rattling noises to engine misfire or power loss. The problem is not universal to all Explorers and appears most often in specific EcoBoost and Ti-VCT engine families within certain model years. Always verify with your VIN whether a recall or service bulletin applies to your vehicle.
Which Ford Explorer models are affected
Engines most commonly implicated
Some EcoBoost-equipped Explorers and certain Ti-VCT V6 configurations have been the focus of timing-chain-related service notices. The exact years vary by engine family, so owners should check their VIN against Ford’s recall and service bulletin databases.
Common symptoms to watch for
The following indicators can suggest a timing-chain problem vs. other engine issues. If you notice any of these, have the vehicle inspected promptly to prevent potential damage.
- Rattling, tapping, or slapping noises from the front of the engine, especially on startup or at idle
- Check Engine Light coming on with codes related to cam or crank timing or misfires
- Engine misfires, rough idle, or reduced power and acceleration
- Unusual engine performance changes, such as stalling or hesitation
These symptoms can also be caused by other problems, but they are commonly reported in cases involving timing-chain wear or tensioner failure. If you hear a loud chain noise, stop driving and have the vehicle inspected as soon as possible.
Causes and risks
Several factors can contribute to timing-chain wear or failure in Explorers. Understanding these can help with prevention and timely maintenance.
- Normal wear of the timing chain with mileage, especially in older engines
- Worn or failing chain tensioners and guides
- Oil starvation or low oil pressure affecting proper chain tension
- Aggressive driving, high RPM operation, or heavy towing increasing strain on the chain system
Left unaddressed, a stretched or failed chain can skip timing or break, potentially causing severe engine damage and expensive repairs.
What to do if you own a Ford Explorer with this issue
Proactive steps can help minimize risk and cost. Follow these recommendations if you suspect timing-chain problems in your Explorer.
- Check your vehicle identification number (VIN) against Ford’s recall and service bulletin databases to see if timing-chain/tensioner-related issues are covered
- Have a qualified technician perform a diagnostic focused on the timing chain, tensioner, and guides
- If a problem is confirmed or likely, prepare for a timing-chain replacement that may include tensioners, guides, and related components (and sometimes the water pump); labor costs can be significant
- Follow maintenance best practices, including timely oil changes with the correct specification, to help reduce wear on chain components
- Avoid prolonged driving with suspected chain issues; arrange towing if there is loud chain noise or sudden loss of power
Timely diagnosis and repair not only restore performance but can prevent catastrophic engine damage and more extensive repairs down the line.
Recalls and service information
Ford has issued recalls and service notices for timing-chain-related concerns on certain Explorer models. Checking for open recalls and service campaigns using your VIN is the safest way to determine if your vehicle is eligible for a free repair or replacement.
- Recalls: Some model years have campaigns focusing on timing-chain tensioners or guides; repairs under recall are typically covered by Ford
- Service bulletins: Independent shops and dealers may reference TSBs that address symptoms, diagnostic steps, and repair procedures even if there is no recall
If your Explorer is listed in a recall or service bulletin, contact a Ford dealer to schedule the recommended service promptly.
Summary
In short, timing-chain problems on a Ford Explorer stem from wear or failure of the chain, tensioner, or guides in certain engines. Symptoms range from engine noises to misfires and power loss, and the risk of serious engine damage grows if the issue is ignored. The best defense is proactive maintenance, prompt diagnostics if symptoms appear, and checking VIN-based recall/TSB status to determine eligibility for covered repairs.
How much does it cost to fix a timing chain on a Ford Explorer?
The cost to replace a Ford Explorer timing chain typically ranges from \$1,200 to over \$2,000, but it can be significantly higher depending on the engine model and whether the engine needs to be removed for the job. The final price includes parts like the timing chain, tensioners, and fluids, plus the labor, which is the most significant expense.

Factors influencing the cost
- Engine type: V6 engines, especially overhead cam (OHC) models, are often more complex and require engine removal, increasing labor costs.
- Labor time: The replacement can take five to eight hours or more, which is a significant portion of the total cost.
- Parts: While some parts are relatively inexpensive, a full timing chain set includes several components, such as tensioners, guides, and gaskets, which add up.
- Shop type: Dealerships often have higher labor rates than independent mechanics.
- Engine condition: If the timing chain failure has caused other internal engine damage, the total repair cost will increase substantially.
How to get a more accurate estimate
- Provide specific details: Be sure to give the mechanic the exact year, make, model, and engine size of your Ford Explorer.
- Ask for a full quote: Get a detailed quote that includes both parts and labor before authorizing any work.
- Compare quotes: It's a good idea to get estimates from several different mechanics, both dealerships and independent shops, to compare prices.

What year to stay away from Ford Explorer?
You should generally stay away from 2002–2006 Ford Explorers due to widespread transmission failures and other issues like engine and suspension problems. Other years with significant problems include 2016, with a large recall involving faulty fuel tanks and suspension components, and 2020, which had many recalls and customer complaints.
2002–2006 models
- These models are widely considered the least reliable, with a major reputation for transmission failures that can be very expensive to fix.
- Owners also reported engine problems (like timing chain and head gasket issues), suspension wear, and electrical malfunctions.
Other years to approach with caution
- 2016: This year had a recall involving faulty suspension components and a fuel tank.
- 2020: This model year had a high number of recalls and complaints, including issues with the transmission, power loss, and a potential rollaway defect.
- 2008: This model year is also listed by some sources as a year to avoid due to low owner satisfaction scores and recalls.
What Ford engine has timing chain problems?
Ford Edge (2007-2014): The 3.5L V6 engine in the Edge has been known to encounter timing chain problems, often manifesting as rough running or metallic noises. Ford Expedition (2005-2014): Similar to the F-150, the Expedition's 5.4L engine also faced timing chain problems, resulting in costly repairs for some owners.
