Understanding the 3.5L Cyclone V6 Engine Architecture
The heart of your Explorer is the 3.5L Ti-VCT V6 engine, often referred to as the Cyclone engine. It is a robust powerplant that produces 290 horsepower, which is plenty for merging onto highways or light towing.
However, this engine has a unique design feature that every DIYer must understand: the internal water pump. Unlike many vehicles where the water pump is driven by an external belt, this pump is driven by the timing chain.
If this pump fails, it can leak coolant directly into the oil pan. This creates a “milkshake” consistency that can destroy your engine bearings in minutes. Regularly checking your oil for a milky appearance is a vital safety step for any owner.
The Importance of the Weep Hole
Ford designed a “weep hole” on the side of the engine block to give you a warning sign. If you see coolant dripping from the side of the engine, it usually means the internal seal has failed. Do not ignore this, as a full failure is often imminent.
Replacing this pump is a labor-intensive job that requires removing the timing cover. If you are a weekend mechanic, ensure you have a full set of timing alignment tools before attempting this repair at home.
Spark Plug and Ignition Coil Maintenance
The 3.5L V6 is relatively easy on spark plugs, but the rear bank (cylinders 1, 2, and 3) is tucked under the intake manifold. To change them, you must remove the upper intake plenum.
Always use a new intake manifold gasket when reassembling to prevent vacuum leaks. Use iridium-tipped plugs to ensure you don’t have to perform this labor-intensive task again for another 100,000 miles.
The 2013 Ford Explorer Limited 3.5L V6 4WD SUV Power Transfer Unit (PTU) Survival Guide
One of the most discussed components of the 2013 ford explorer limited 3.5l v6 4wd suv is the Power Transfer Unit, or PTU. This is the gearbox that sends power from the front transaxle to the rear wheels.
Ford originally marketed the PTU fluid as “filled for life,” but many enthusiasts and technicians disagree. The unit sits very close to the exhaust catalytic converter, which causes the small amount of oil inside to “cook” and turn into a thick sludge.
When the fluid breaks down, the internal gears can overheat, leading to a catastrophic failure of the 4WD system. You might notice a “burnt oil” smell or a high-pitched whine from the front end if the PTU is struggling.
How to Service a “Non-Serviceable” PTU
Most 2013 models do not have a drain plug on the PTU, only a fill plug. To change the fluid, you will need a fluid extraction pump and a thin suction tube to vacuum out the old gear oil.
Replace the old fluid with a high-quality 75W-140 full synthetic gear oil. Doing this every 30,000 miles is the best insurance policy you can buy for your drivetrain, especially if you tow or drive in heavy stop-and-go traffic.
Signs of PTU Seal Failure
Check the area where the passenger-side intermediate shaft enters the PTU. If you see dark, oily residue, the seals may be weeping. Replacing these seals early can prevent the unit from running dry and seizing up while you are driving.
Suspension and Steering: Managing the Weight
The Explorer is a heavy vehicle, and that weight puts significant stress on the front suspension components. The 2013 ford explorer limited 3.5l v6 4wd suv often experiences wear in the lower control arm bushings and ball joints around the 80,000-mile mark.
If you hear a “clunk” when driving over speed bumps or feel a vibration in the steering wheel at highway speeds, it is time for an inspection. Worn bushings can also cause uneven tire wear, which is an expensive problem to ignore.
The Rear Toe Link Recall
It is important to note that many 2013 Explorers were subject to a recall regarding the rear suspension toe links. These links can fracture, leading to a sudden loss of steering control in the rear.
Check your VIN on the Ford owner portal to ensure this recall has been performed. If you are working on the rear suspension yourself, always use grade 10.9 hardware and torque everything to factory specifications to maintain safety.
Electric Power Assisted Steering (EPAS)
The 2013 model uses an electric rack-and-pinion system rather than a traditional hydraulic pump. This improves fuel economy but can be prone to electronic glitches. If your steering feels “notchy” or heavy, check the electrical connectors for corrosion before replacing the entire rack.
Maximizing the Terrain Management System for Off-Roading
While the Limited trim is luxury-focused, the 4WD system is surprisingly capable. The center console features a Terrain Management System dial that allows you to optimize the 2013 ford explorer limited 3.5l v6 4wd suv for different surfaces.
Each setting changes the throttle mapping, transmission shift points, and how the traction control interacts with the braking system. Understanding these modes is key to not getting stuck on a trail or in deep snow.
- Normal Mode: Best for everyday pavement, prioritizing fuel efficiency and smooth shifts.
- Mud/Ruts Mode: Allows for more wheel spin to help clear debris from tire treads.
- Sand Mode: Keeps the transmission in lower gears longer to maintain momentum.
- Grass/Gravel/Snow Mode: Provides early upshifts and dampened throttle response to prevent slipping.
Hill Descent Control
In the center of the terrain dial is the Hill Descent Control button. This is a “pro” feature for off-roading that manages braking automatically while you descend steep, slippery grades.
When engaged, you can take your feet off the pedals and focus entirely on steering. It uses the ABS module to pulse the brakes on individual wheels, keeping the vehicle straight and controlled without locking up the tires.
Interior Tech and the MyFord Touch System
The Limited trim comes standard with the MyFord Touch infotainment system. In the 2013 ford explorer limited 3.5l v6 4wd suv, this system was known for being a bit “buggy” in its early years.
If your screen freezes or the Bluetooth stops connecting, the first step is a Master Reset in the settings menu. If that fails, ensure you have the latest software version installed via a USB drive from the Ford support website.
The 110V Power Outlet and Inverter
Many owners forget about the household-style 110V outlet located in the second row. This is powered by a small inverter under the console. It is perfect for charging laptops or running small camping accessories, but it has a low wattage limit.
Avoid plugging in high-draw items like hair dryers or coffee makers, as this will blow the dedicated fuse. If the outlet isn’t working, check the passenger-side kick panel fuse box for a 20-amp fuse that may have popped.
A Buyer’s Checklist: What to Inspect
If you are looking to purchase a used 2013 ford explorer limited 3.5l v6 4wd suv, your inspection should go beyond a simple test drive. Because these vehicles are often used for family duties, they can hide wear and tear in specific areas.
- Check the PTU: Look for leaks and ask the owner if the fluid has ever been changed.
- Inspect the Water Pump: Use a flashlight to look for orange or green crusty residue around the engine block’s weep hole.
- Test the 4WD: Find a gravel patch and engage the different terrain modes to ensure the rear wheels are receiving power.
- Examine the Liftgate: The plastic “Explorer” applique on the rear hatch is notorious for cracking.
- Listen for Hub Bearings: A “humming” sound that changes with vehicle speed often indicates a failing wheel hub assembly.
Check the Cooling System
Open the coolant reservoir (when the engine is cold!) and look for discoloration. If the coolant looks like chocolate milk, walk away from the deal, as the internal water pump has likely already failed and contaminated the oil.
Frequently Asked Questions About the 2013 ford explorer limited 3.5l v6 4wd suv
What is the towing capacity of the 2013 Ford Explorer Limited 3.5L V6?
When properly equipped with the factory Class III towing package, this SUV can tow up to 5,000 pounds. Without the factory package, the limit is significantly lower (usually 2,000 lbs) because the vehicle lacks the heavy-duty engine oil cooler.
How often should I change the oil in my 3.5L V6?
While the Intelligent Oil-Life Monitor might suggest 10,000 miles, most experts recommend a 5,000 to 7,500-mile interval using a full synthetic 5W-20 oil. This helps prevent sludge buildup, which is critical for the health of the timing chain and internal water pump.
Why does my Explorer smell like rotten eggs under heavy acceleration?
This is often caused by the catalytic converters getting too hot or failing. However, it can also be a sign of the PTU fluid overheating and venting gases into the cabin. It is best to have a technician check the PTU fluid level and condition immediately.
Is the 2013 Ford Explorer good in deep snow?
Yes, the 4WD system and “Snow” mode are very effective at managing wheel slip. However, the factory-installed tires on the Limited trim are often street-biased. For true winter performance, consider upgrading to a dedicated winter tire or a high-quality “All-Weather” tire with the 3-Peak Mountain Snowflake rating.
