Whether you are a seasoned DIY mechanic or a first-time car owner, this guide is designed for you. We focus on practical, real-world advice that saves you a trip to the dealership. Let’s dive into the details of fixing your Fusion’s cooling system.
Understanding the Role of the Degas Bottle
In the 2013 Ford Fusion, the coolant reservoir is often referred to as a degas bottle. Unlike older overflow tanks, this is a pressurized component of your cooling system. It does more than just hold extra fluid; it helps remove air bubbles from the circulating coolant.
Air is the enemy of your engine’s cooling efficiency. When air pockets form, they can cause “hot spots” in the cylinder head. The degas bottle allows these bubbles to settle out, ensuring that only pure liquid flows through your radiator and engine block.
Because this tank is under constant pressure and high heat, the plastic eventually becomes brittle. This leads to hairline cracks, usually along the molded seams or near the hose inlets. Identifying these leaks early is the key to preventing a total breakdown.
Signs You Need a 2013 ford fusion coolant reservoir replacement
How do you know for sure that the tank is the culprit? One of the most obvious signs is a visible crack in the translucent plastic. Over time, the heat cycles of the engine cause the material to yellow and weaken, making it prone to splitting.
You might also notice a persistent low coolant light on your instrument cluster. If you find yourself topping off the fluid every few weeks, the system is losing pressure somewhere. Check the area around the reservoir for white crusty residue, which is dried coolant.
Another sign is the smell of syrup when the engine is hot. If the 2013 ford fusion coolant reservoir replacement is delayed, the leak may worsen suddenly. This could leave you stranded with an empty system and a steaming hood.
Common Failure Points
- The Pressure Cap: Sometimes the cap seal fails, allowing steam to escape.
- The Return Port: The small nipple at the top of the tank often snaps off during other repairs.
- Bottom Seams: The point where the two halves of the tank are joined is a frequent leak site.
Tools and Materials Required
Before you start, gather everything you need to avoid mid-job trips to the parts store. Most of these tools are standard in a basic DIY kit. Having them ready will make the process much smoother.
You will need a set of socket wrenches, specifically 8mm and 10mm sizes. A pair of long-reach pliers or specialized hose clamp pliers is also essential for those stubborn spring clamps. Ford uses constant-tension clamps that can be tricky with standard pliers.
Don’t forget the safety gear. Wear nitrile gloves to protect your skin from the chemicals in the coolant. Eye protection is also recommended, as pressurized fluid can spray if the system isn’t fully cooled down.
Parts List
- New Coolant Reservoir (OEM or high-quality aftermarket).
- New Reservoir Cap (Highly recommended to replace with the tank).
- Motorcraft Orange or Yellow Concentrated/Premixed Coolant.
- Distilled Water (If using concentrated coolant).
Step-by-Step 2013 ford fusion coolant reservoir replacement Guide
Safety is your first priority when working on any cooling system. Never attempt to open the reservoir cap while the engine is hot. The pressurized steam can cause severe burns instantly. Wait at least two hours after driving before you begin.
- Drain the Fluid: You do not need to drain the entire radiator. Use a fluid transfer pump or a large syringe to suck the old coolant out of the reservoir. This minimizes the mess in your engine bay.
- Disconnect the Hoses: There are typically two or three hoses attached to the tank. Use your pliers to slide the spring clamps back. Gently twist the hoses to break the seal before pulling them off.
- Remove Mounting Bolts: Locate the bolts holding the tank to the chassis. On the 2013 Fusion, these are usually 10mm bolts. Keep them in a magnetic tray so they don’t disappear into the engine bay.
- Extract the Old Tank: Lift the reservoir upward. There may be a plastic tab at the bottom that slots into a rubber grommet. Give it a firm but controlled pull to release it.
- Install the New Reservoir: Slide the new tank into the mounting position. Ensure the bottom tab seats correctly into its grommet. This prevents the tank from vibrating and cracking later.
- Reattach Hoses and Bolts: Reinstall the mounting bolts first to steady the tank. Then, slide the hoses back onto their respective ports. Position the spring clamps exactly where they were originally to ensure a leak-free seal.
Choosing the Right Coolant
The 2013 Ford Fusion originally came from the factory with Motorcraft Orange coolant. However, Ford has recently transitioned to a newer Yellow formula (WSS-M97B57-A1). This new yellow coolant is backwards compatible and offers better long-term protection.
Avoid using “Universal” coolants found at big-box stores unless they specifically list Ford’s specification. Mixing incompatible coolants can lead to gel formation. This sludge will clog your heater core and radiator, leading to expensive repairs.
Always use distilled water if you are mixing concentrate. Tap water contains minerals like calcium and magnesium. These minerals will scale up inside your engine, reducing heat transfer and eventually causing the water pump to fail.
Crucial Post-Installation: Bleeding the Air
After finishing the 2013 ford fusion coolant reservoir replacement, you cannot simply drive away. Air trapped in the system will cause the temperature to spike. You must “burp” the system to ensure all air is purged.
Fill the new reservoir to the “Max” line with your 50/50 coolant mix. Leave the cap off for the initial warm-up phase. Start the engine and turn your heater to the highest temperature setting with the fan on low.
Watch the reservoir level as the engine reaches operating temperature. When the thermostat opens, the fluid level will likely drop suddenly. Top it off as needed. Once the bubbles stop appearing and you have hot air blowing from the vents, the process is nearly complete.
The Final Check
Reinstall the pressure cap tightly. Take the car for a short 10-minute drive, keeping a close eye on the temp gauge. After the engine cools down completely, check the level one last time. It is normal to add a small amount after the first heat cycle.
Common Pitfalls and Pro Tips
One common mistake is over-tightening the mounting bolts. The reservoir is plastic, and the mounting ears can crack if you apply too much torque. Just snug them down until they are firm.
Another tip involves the hose clamps. If your original spring clamps feel weak or show signs of rust, replace them with stainless steel worm-gear clamps. These provide a more adjustable and reliable seal on older hoses that may have hardened.
If you have the 1.6L EcoBoost engine, be especially careful. This specific engine had recalls regarding coolant loss and engine fires. Ensuring your reservoir is in perfect condition is not just about maintenance; it is a critical safety requirement for this model.
Environmental Responsibility
Coolant is toxic to animals and the environment. Its sweet smell often attracts pets and wildlife, but ingesting even a small amount can be fatal. Always perform this repair over a drip tray or cardboard.
Collect your old fluid in a sealed container. Most local auto parts stores or municipal recycling centers will accept used coolant for free. Never pour it down a storm drain or into the dirt.
Cleaning up spills immediately with kitty litter or specialized absorbent pads is the best practice. Rinse the area with water after the absorbent has been swept up to ensure no residue remains for pets to lick.
Frequently Asked Questions About 2013 ford fusion coolant reservoir replacement
How long does a coolant reservoir replacement take?
For a beginner, the job usually takes about 45 minutes to an hour. This includes the time needed to drain the old fluid and bleed the air out of the system. A professional can often do it in 20 minutes.
Can I drive with a cracked coolant reservoir?
It is not recommended. A crack prevents the system from holding pressure, which lowers the boiling point of the coolant. This can lead to localized boiling inside the engine and permanent damage to the cylinder head.
Why is my new reservoir turning brown?
If your new tank discolors quickly, it may indicate rust in the engine block or a failing head gasket. If the fluid looks like a “chocolate milkshake,” stop driving immediately, as oil is likely mixing with your coolant.
Do I need to replace the cap too?
Yes, it is best practice to replace the cap. The cap contains a pressure relief valve that is calibrated to a specific PSI. If this valve sticks, it can cause the new tank to burst under pressure.
Is there a difference between the Hybrid and Gas reservoirs?
Yes, the 2013 Ford Fusion Hybrid has a different cooling layout, often involving two separate cooling loops. Always verify your specific sub-model (S, SE, Titanium, or Hybrid) when ordering parts.
