2013 Ford Fusion Thermostat Location – A Guide To Locating
The thermostat on a 2013 Ford Fusion is typically located on the driver’s side of the engine block, integrated into the coolant housing assembly near the water pump. Accessing this component requires removing several peripheral parts, making it a moderately involved task for the home mechanic.
Is your cabin heater blowing cold air, or has your temperature gauge started creeping into the red zone? These are classic signs that your cooling system is struggling, often due to a stuck thermostat. Finding the 2013 ford fusion thermostat location is the first step in restoring your engine’s thermal efficiency and preventing long-term damage.
We know that staring into a cramped engine bay can be intimidating, especially when you are just trying to get back on the road. In this guide, we will walk you through exactly where to look, what tools you need, and how to safely swap out this critical component without turning a simple repair into a weekend-long headache.
Understanding the 2013 Ford Fusion Thermostat Location
To identify the 2013 ford fusion thermostat location, you need to look toward the driver’s side of the engine, specifically tucked behind the air cleaner assembly and the coolant hoses. Depending on whether you have the 1.6L EcoBoost, 2.0L EcoBoost, or the 2.5L Duratec engine, the exact housing shape may vary slightly, but the general area remains the same.
The thermostat is housed within a plastic or metal assembly that connects the engine block to the radiator via the upper radiator hose. Because these vehicles utilize a pressurized cooling system, the housing is designed to be robust, yet it is susceptible to plastic fatigue over high mileage.
Pro Tip: Before you start pulling parts, always ensure the engine is completely cool. Opening a cooling system while the engine is hot can lead to severe burns from pressurized coolant spray.
Tools Required for the Job
Before you dive in, gather your supplies to avoid mid-project trips to the auto parts store. Having the right tools makes the 2013 ford fusion thermostat location much easier to navigate.
- A set of metric sockets and a ratchet (specifically 8mm and 10mm).
- A sturdy flat-head screwdriver or hose clamp pliers for the coolant lines.
- A drain pan to catch the inevitable spill of engine coolant.
- A new thermostat gasket or O-ring (often included with the new part).
- A funnel and the correct specification of coolant (Motorcraft specialty green or orange, depending on your manual).
Step-by-Step Access and Removal
Once you have located the assembly, you must clear the path. Start by disconnecting the negative battery terminal to prevent any accidental shorts while working near the alternator or electrical sensors.
Removing Peripheral Obstructions
You will likely need to remove the air intake box to get a clear line of sight to the housing. Loosen the hose clamps on the intake tube and pull the assembly upward; it is usually held in place by rubber grommets that pop off with a firm tug.
Draining the Coolant
Position your drain pan directly under the lower radiator hose or the drain petcock. Loosen the radiator drain plug slowly to allow the coolant to flow into your pan rather than all over your garage floor. Always dispose of used coolant properly at a recycling center, as it is toxic to pets and wildlife.
Installing the New Thermostat
With the housing exposed, remove the bolts securing it to the engine block. Be prepared for a small amount of residual coolant to leak out once the housing is pulled away from the block.
Clean the mating surface on the engine block thoroughly with a clean rag. Any old gasket material or debris left behind will lead to a persistent leak once you refill the system. Place the new thermostat in the correct orientation—the spring side should always face toward the engine block.
Tighten the housing bolts in an alternating, “star” pattern to ensure even pressure on the gasket. Do not over-torque these bolts, as the plastic housing can easily crack, leading to a much larger repair later.
Refilling and Bleeding the Cooling System
Replacing the part is only half the battle; the 2013 ford fusion thermostat location is at a high point in the engine, meaning air pockets are common. Air trapped in the system can cause overheating even with a brand-new thermostat.
Fill the coolant reservoir to the “Max” line, then start the engine with the heater set to the highest temperature. As the engine warms up, the thermostat will open, and the coolant level in the reservoir will drop as the air is pushed out.
Continue to top off the reservoir as needed. Once the engine reaches operating temperature and you feel hot air coming from the vents, you can be confident that the system is properly bled.
Frequently Asked Questions About the Thermostat
How do I know if my thermostat is stuck closed?
If your engine temperature gauge rises quickly into the red zone after only a few minutes of driving, the thermostat is likely stuck closed. This prevents coolant from circulating through the radiator, causing the engine to overheat rapidly.
Can I drive with a bad thermostat?
It is highly discouraged. Driving with a stuck-closed thermostat will lead to engine overheating and potential head gasket failure. If it is stuck open, your engine will take a long time to warm up, resulting in poor fuel economy and increased engine wear.
Do I need to replace the entire housing?
On many 2013 Ford Fusion models, the thermostat is sold as part of a housing assembly. Even if the internal spring mechanism is the only part that failed, replacing the entire housing is recommended to prevent future leaks from the plastic casing.
Is it necessary to use OEM coolant?
Yes, Ford cooling systems are specific about the chemical composition of their coolant. Using the wrong type can lead to corrosion or “sludging” within the radiator and heater core. Always check your owner’s manual for the correct fluid specification.
Tackling the 2013 ford fusion thermostat location may seem daunting, but with a methodical approach and the right tools, you can handle it yourself. Keep your workspace clean, take your time with the air-bleeding process, and don’t rush the reassembly. Taking these steps ensures your Fusion stays reliable on the road. Stay safe, and enjoy the satisfaction of a job well done!
