Ford Taurus Engine Timing Set Replacement Guide (2013-2018)
Understanding the critical timing set replacement for your 2013-2018 Ford Taurus, especially for the 3.5L engine.
- For the 3.5L V6, a failing water pump often causes timing chain failure by leaking coolant into the oil.
- Always replace the water pump when replacing the timing chain set on the 3.5L engine.
- A rattling noise on cold startup is a key early warning sign that should not be ignored.
- This is a complex, labor-intensive job that is not recommended for DIY unless you are an experienced mechanic with special tools.
Is Your Taurus Showing Signs of Timing Chain Trouble?
If you own a 2013-2018 Ford Taurus, particularly one with a 3.5L V6 engine, it's important to be aware of potential timing system issues. While timing chains are built to last longer than timing belts, they can still wear out or fail, leading to serious engine problems. The most common symptoms are often subtle at first, but ignoring them can lead to expensive repairs.
Known Issue: The Internal Water Pump
A significant design issue on the 3.5L Duratec V6 engine is the internal, timing-chain-driven water pump. 🎬 See how a water pump failure impacts your Ford Taurus engine. When the water pump seal fails, it can leak coolant directly into the engine oil. This contamination can ruin engine bearings and accelerate the wear of timing chain components, leading to a much larger failure. Often, a water pump failure is the root cause of a timing chain replacement job on these engines. Because of this, it is highly recommended to replace the water pump whenever you replace the timing set.
Symptoms of a Failing Timing Set
Pay close attention to how your engine sounds and performs. Here are the key warning signs:
🎬 Watch this video to see the top 5 timing chain symptoms.- Rattling Noise on Startup: A brief rattle or clatter for a few seconds when you start the engine cold is a classic sign of a loose timing chain or failing tensioners.
- Persistent Engine Rattle: A rattling or buzzing sound from the front of the engine that doesn't go away as it warms up.
- Check Engine Light: Fault codes like P0016, which indicates a mismatch between the crankshaft and camshaft positions, often point directly to a stretched timing chain.
- Engine Misfires or Rough Idle: If the chain has stretched or jumped a tooth, the engine's timing will be off, causing it to run rough, misfire, or vibrate excessively.
- Metal Shavings in Oil: During an oil change, finding small metal particles in the used oil or filter is a serious red flag that parts of the timing chain or guides are breaking down.
Choosing the Right Aftermarket Timing Set
When it's time for a replacement, you'll have to choose between OEM (Original Equipment Manufacturer) and aftermarket parts. For the Taurus, OEM parts have known issues, particularly with the water pump design. High-quality aftermarket kits can be a reliable and cost-effective alternative.
Brands like INA are known for producing quality timing components. When shopping, look for a complete kit that includes not just the chains, but also the tensioners, guides, and sprockets (phasers). Given the complexity of the job, using a comprehensive kit ensures all wear items are replaced at once, preventing future failures.
Pro Tip: Replace It All at Once
This is not a job you want to do twice. Since accessing the timing set requires significant labor, always replace the entire kit—chains, guides, tensioners, and phasers. Crucially, for the 3.5L engine, always replace the water pump at the same time. The extra part cost is minimal compared to the labor cost of having to go back in later.
| Part/Service | Estimated Cost |
|---|---|
| New OEM Timing Set | $350 - $550 |
| New Aftermarket Timing Set (INA) | $251 - $473 |
| Shop Labor | $1,200 - $1,800 |
| Total Professional Job (Aftermarket) | $1,451 - $2,273 |
Frequently Asked Questions
Is this a DIY job?
This is an advanced repair. It requires special tools to hold the camshafts in place, extensive disassembly of the engine's front end, and precise knowledge of timing marks. 🎬 View a detailed guide on timing marks and chain replacement. For most owners, this job is best left to a professional mechanic. Incorrect installation can lead to catastrophic engine damage.
Are there any recalls for the timing chain on the 2013-2018 Taurus?
No, there are no specific recalls from the NHTSA for timing chain failure on the 2013-2018 Ford Taurus. Any repairs will be at the owner's expense unless covered by a warranty.
How long does a timing chain last on a Ford Taurus?
A timing chain should ideally last the life of the engine, but issues can arise, often around 100,000 miles or more. The failure of the internal water pump on the 3.5L V6 is a common reason for premature timing chain problems.
What happens if the timing chain breaks while driving?
If the timing chain breaks, the engine will stop immediately. Because the 3.5L is an interference engine, a broken chain will likely cause the pistons to hit the valves, resulting in severe and often irreparable engine damage. This is why addressing the warning signs early is so critical.
