Let’s dive into the world of forced induction and get your Explorer breathing right again.
Recognizing the Symptoms of a Failing Turbocharger
Before you commit to a full replacement, you must confirm that the turbocharger is indeed the culprit. The EcoBoost system is complex, and sometimes a simple vacuum leak or a faulty sensor can mimic turbo failure. However, certain signs are definitive indicators that the internal components of the turbo have reached the end of their life.
The most common symptom is a significant loss of acceleration, often accompanied by a “limp mode” activation. You might also see a Check Engine Light with codes like P0299, which indicates an underboost condition. This often happens when the wastegate arm becomes loose or the compressor wheel can no longer spin at the required RPM.
Keep an ear out for unusual noises, specifically a “dentist drill” or siren sound that rises in pitch with engine speed. This usually points to shaft play, where the internal bearings have failed, allowing the blades to scrape against the housing. Additionally, blue smoke from the exhaust suggests that the oil seals inside the turbo have failed, allowing lubricant to leak into the combustion chamber.
Essential Tools for a 2016 ford explorer turbo replacement
Performing a 2016 ford explorer turbo replacement requires more than just a basic socket set. Because the turbocharger is tucked away near the firewall (especially on the 3.5L models), you will need specialized tools to reach tight spaces. Proper preparation will save you hours of frustration and prevent rounded-off bolts.
- Socket Set: A full range of 1/4-inch and 3/8-inch drive sockets, including deep-well options.
- Swivel Joints and Extensions: Multiple lengths of extensions and universal joints are mandatory for reaching manifold nuts.
- E-Torx Sockets: Ford uses external Torx bolts for many heat shields and mounting brackets.
- Torque Wrench: You must tighten the manifold and oil line bolts to exact factory specifications.
- Crows Foot Wrenches: These are incredibly helpful for loosening oil and coolant lines in cramped quarters.
- Drain Pan: You will need to catch both engine oil and coolant during the process.
Required Parts and Supplies
Never reuse old gaskets or seals when installing a new turbocharger. Heat cycles cause these components to harden and deform, making a leak almost certain if they are reused. Order a complete turbo installation kit that includes the manifold gasket, oil feed and return gaskets, and the crush washers for the coolant lines.
It is also highly recommended to replace the oil feed line itself. These thin lines can develop carbon buildup (coking) over time, which restricts oil flow. A restricted line will starve your brand-new turbo of lubrication, causing it to fail within minutes of the first start. Always use high-quality, full-synthetic oil and a fresh motorcraft filter for the post-installation oil change.
Step-by-Step Guide to the Replacement Process
The 2016 Ford Explorer typically features either the 2.3L inline-four or the 3.5L V6 EcoBoost. While the layout differs, the fundamental steps for a 2016 ford explorer turbo replacement remain similar. Always ensure the engine is completely cool before starting, as the turbocharger retains heat longer than almost any other component.
Step 1: Preparation and Fluid Drainage
Start by disconnecting the negative battery terminal to prevent any electrical shorts. Raise the front of the vehicle using a floor jack and secure it firmly on jack stands. Never work under a car supported only by a jack. Remove the plastic engine cover and the lower splash shield to gain access to the underside of the engine.
Locate the radiator drain petcock and drain the coolant into a clean container. If the coolant is fresh, you can reuse it, but most experts recommend using new Orange-colored coolant (or the updated Yellow formula) approved by Ford. Next, drain the engine oil. Removing the oil now prevents a mess when you disconnect the turbo’s oil return line later.
Step 2: Removing Intake and Exhaust Plumbing
Loosen the clamps on the air intake pipe and remove it from the turbo inlet. Inspect the inside of the pipe for excessive oil or metal shavings; if you find metal bits, you must flush the intercooler to prevent those fragments from being sucked into the new turbo. Disconnect the vacuum lines going to the wastegate actuator and the bypass valve.
From underneath the vehicle, disconnect the downpipe from the exhaust side of the turbocharger. These bolts are often rusted and stubborn. Apply a generous amount of penetrating oil and let it soak for at least 30 minutes. If a bolt feels like it might snap, apply heat with a small torch to expand the metal before attempting to turn it again.
Step 3: Disconnecting Oil and Coolant Lines
The turbocharger is cooled by engine coolant and lubricated by engine oil. There are four lines in total: oil feed, oil return, coolant feed, and coolant return. Use your crows foot wrenches to break the fittings loose. Be prepared for a small amount of residual fluid to leak out as these lines are disconnected.
Check the oil return line for any signs of sludge. If the line is restricted, the oil will “back up” into the turbo, forcing its way past the seals and causing smoke. Most technicians replace the oil feed line as a standard “insurance” policy during a 2016 ford explorer turbo replacement to ensure maximum longevity for the new unit.
Step 4: Removing the Old Turbocharger
The turbo is usually bolted to the exhaust manifold or integrated into it. Remove the mounting nuts holding the turbo to the manifold. On the 3.5L V6, space is extremely tight near the firewall, so you may need to remove a few heat shields first. Once the nuts are off, carefully wiggle the turbocharger off the studs.
Be careful not to drop the unit, as it is surprisingly heavy. Once the turbo is out, inspect the exhaust manifold for any cracks. If the manifold is warped or cracked, the new turbo will not seal properly, leading to an exhaust leak that will ruin your fuel economy and produce a loud ticking sound.
Step 5: Preparing and Installing the New Turbo
Before installing the new unit, compare it side-by-side with the old one. Ensure the clocking (the orientation of the housings) is identical. Clean the mounting surfaces on the exhaust manifold using a plastic scraper or a scuff pad. Do not use a metal scraper that could gouge the surface and cause a permanent leak.
Install the new manifold gasket. Place the new turbocharger onto the studs and start the nuts by hand to avoid cross-threading. Tighten them in a crisscross pattern to the specified torque. Reconnect the oil and coolant lines using new crush washers. This is the most critical part of the job; a tiny leak here can lead to engine failure or a fire.
Critical Post-Installation Steps
You cannot simply start the engine as soon as the last bolt is tightened. The new turbocharger is bone-dry inside. If you start the engine and the turbo spins up to 100,000 RPM without oil, the bearings will be destroyed instantly. This is a common mistake that turns a successful 2016 ford explorer turbo replacement into an expensive disaster.
Before connecting the oil feed line to the top of the turbo, use a small squirt can to pour clean engine oil into the oil inlet hole. Spin the compressor wheel by hand to distribute the oil. Once connected, you should perform a dry crank. Disconnect the fuel pump fuse or the ignition coils and crank the engine for 10-second intervals until the oil pressure light goes out. This primes the system safely.
Once the system is primed, reconnect the ignition/fuel and start the engine. Let it idle for at least 10 to 15 minutes. Do not rev the engine. While it idles, use a flashlight to inspect every connection for leaks. Look for any signs of smoke or dripping fluids. It is normal to see a small amount of smoke coming off the exhaust manifold as the oils from your hands and the new parts burn off.
Common Pitfalls and How to Avoid Them
One of the biggest mistakes DIYers make is failing to address the root cause of the original turbo failure. Turbochargers rarely fail on their own; they are usually killed by poor oil quality, restricted oil flow, or debris. If you don’t change your oil every 5,000 miles, carbon deposits will eventually clog the small passages that feed the turbo.
Another pitfall is over-tightening the small bolts on the oil and coolant lines. These are often made of soft metals or use hollow “banjo” bolts. If you over-torque them, they will snap, leaving you with a nightmare extraction job. Always use a torque wrench and follow the manufacturer’s specs precisely.
Finally, ensure the air intake system is completely sealed. A loose clamp on the intake side can allow “unmetered air” into the engine, causing a lean condition. Worse, it can allow dust and dirt to bypass the filter and sandblast the delicate compressor wheel blades, leading to premature wear and failure.
Frequently Asked Questions About 2016 Ford Explorer Turbo Replacement
How long does it take to replace the turbo on a 2016 Ford Explorer?
For an experienced DIYer with the right tools, the job typically takes between 6 to 10 hours. On the 3.5L EcoBoost, the rear turbo (closest to the firewall) is much more difficult to access than the front one, which can add significant time to the project.
Do I need to replace both turbos if only one is failing?
While you don’t have to replace both, it is often recommended on high-mileage vehicles. If one turbo has failed due to age and wear, the other is likely not far behind. Replacing both at once saves you from having to tear the engine apart a second time in the near future.
Can I drive my Explorer with a failing turbo?
It is not recommended. A failing turbo can send metal fragments into the engine intake or leak oil into the exhaust, which can destroy your catalytic converters. If the turbo seizes completely, it can block the exhaust flow, causing the engine to stall and potentially leaving you stranded.
What is the average cost of a 2016 ford explorer turbo replacement?
If you perform the work yourself, you will likely spend between $600 and $1,200 on parts and supplies. A professional shop will typically charge between $2,000 and $4,500, depending on labor rates and whether you are replacing one or both turbochargers.
Final Thoughts on Your Turbo Project
Completing a 2016 ford explorer turbo replacement is a major milestone for any DIY mechanic. It requires patience, the right tools, and a strict adherence to safety protocols. By taking your time to clean the surfaces, prime the new unit with oil, and check for leaks, you ensure that your Explorer will run smoothly for many years to come.
Remember that preventative maintenance is the best way to protect your new investment. Use high-quality synthetic oil, change your air filters regularly, and allow the engine to idle for a minute after a long drive to let the turbo cool down. These simple habits will prevent the heat-related issues that lead to turbo failure in the first place.
Stay safe, keep your workspace clean, and enjoy the renewed power of your EcoBoost engine. You’ve got this!
