2017 Ford F150 Upper Radiator Hose Replacement
Replacing a worn or leaking upper radiator hose on your 2017 Ford F-150 is a straightforward DIY task that prevents engine overheating and costly repairs. This guide provides the exact steps, tool list, and professional tips needed to swap out the hose and bleed the cooling system correctly.
We’ve all been there—you spot a puddle of orange or yellow fluid under your truck or smell that sweet, sickly scent of hot antifreeze after a long drive. If you have noticed steam or a drop in your coolant reservoir levels, a 2017 ford f150 upper radiator hose replacement is often the most effective and affordable fix.
The cooling system on the thirteenth-generation F-150 is robust, but the plastic quick-connect fittings and rubber hoses eventually succumb to heat cycles and pressure. Don’t let a minor leak turn into a warped cylinder head or a blown head gasket when you are miles away from the nearest town.
In this guide, I will walk you through the entire process, from draining the system to installing the new hose and ensuring your engine stays cool. Whether you have the 2.7L EcoBoost, the 3.5L EcoBoost, or the 5.0L V8, these steps will help you get back on the road with confidence.
Understanding the 2017 ford f150 upper radiator hose replacement and Why It Fails
The upper radiator hose is a critical component that carries hot coolant from the engine block back to the radiator to be cooled. Over time, the constant fluctuation between freezing outdoor temperatures and 200-degree engine heat causes the rubber to degrade and lose its elasticity.
On the 2017 models, Ford utilized a combination of traditional rubber hoses and plastic quick-connect fittings. While these fittings make assembly at the factory faster, the internal O-rings are notorious for flattening out and leaking as the truck ages.
Common signs of failure include crusty white or colored residue around the connection points or a hose that feels excessively soft or “mushy” when squeezed. If you see any bulging or visible cracks in the rubber, it is time to perform a 2017 ford f150 upper radiator hose replacement before the hose bursts under pressure.
Essential Tools and Parts for the Job
Before you crack open the cooling system, you need to have the right supplies on hand. Having everything ready prevents the frustration of being stuck halfway through the job without a way to refill your truck.
- New Upper Radiator Hose: Ensure it matches your specific engine (EcoBoost vs. V8).
- Replacement Coolant: 2017 models typically use Motorcraft Orange or the newer backward-compatible Motorcraft Yellow.
- Large Drain Pan: To catch the old coolant and prevent environmental contamination.
- Pliers: Long-nose or specialized hose clamp pliers for the constant-tension clamps.
- Small Flathead Screwdriver: Useful for releasing the metal retaining clips on quick-connect fittings.
- Distilled Water: To mix with concentrated coolant if you aren’t using a pre-diluted 50/50 mix.
Always check your owner’s manual or the cap on your degas bottle (coolant reservoir) to verify the correct fluid type. Mixing incompatible coolants can lead to “sludging,” which clogs the tiny passages in your heater core and radiator.
Choosing Between OEM and Aftermarket Hoses
For most owners, a genuine Motorcraft replacement is the safest bet because the fitment is guaranteed. However, if you are an off-roader who subjects your truck to extreme heat, you might consider heavy-duty silicone hoses that offer higher thermal resistance.
Regardless of the brand, ensure the new hose includes the plastic quick-connect housing if your original one is cracked. Some budget hoses require you to reuse the old plastic ends, which often leads to leaks shortly after the repair.
Step-by-Step Guide to Replacing Your Upper Radiator Hose
The 2017 ford f150 upper radiator hose replacement is a job that most DIYers can finish in about an hour. Follow these steps carefully to ensure a leak-free seal and a properly functioning cooling system.
Step 1: Safety First and Engine Prep
Never attempt to open a cooling system while the engine is hot. The system is under significant pressure, and opening the cap can result in a geyser of boiling liquid that causes severe burns.
Park the truck on a level surface and let it sit for at least two hours. Once the upper hose feels cool to the touch, slowly turn the degas bottle cap to vent any remaining pressure before removing it completely.
Step 2: Draining the Coolant
You do not necessarily need to drain the entire radiator for this job, but you must lower the fluid level below the upper hose connection. Locate the plastic petcock drain valve at the bottom of the radiator on the passenger side.
Place your drain pan underneath and slowly loosen the valve. Drain about one gallon of fluid into the pan, then tighten the valve back up; this prevents a massive mess when you pull the hose off the engine block.
Step 3: Removing the Old Hose
The upper hose is held on by a metal spring clip on the radiator side and usually a standard tension clamp on the engine side. Use your small screwdriver to pull the metal clip upward on the quick-connect fitting until it clicks into the “open” position.
Grasp the hose and wiggle it firmly until it slides off the radiator inlet. On the engine side, use your pliers to squeeze the tabs of the tension clamp and slide it back toward the middle of the hose, then pull the hose off the thermostat housing.
Step 4: Cleaning the Connection Points
Before installing the new part, use a clean rag to wipe down the radiator inlet and the engine outlet. Any debris, corrosion, or old rubber bits left behind can prevent the new O-rings from seating properly.
If you see heavy calcification on the metal engine outlet, you can lightly scuff it with a Scotch-Brite pad. A clean surface is the secret to a professional-grade 2017 ford f150 upper radiator hose replacement.
Step 5: Installing the New Upper Hose
Slide the engine-side of the hose onto the thermostat housing first. Position the tension clamp about half an inch from the end of the hose and release the pliers to lock it in place.
For the quick-connect end, ensure the metal clip is in the “down” or “locked” position. Push the fitting onto the radiator inlet until you hear a distinct audible click; pull back on it slightly to confirm it is securely locked.
Refilling and Bleeding the Cooling System
Once the hose is secure, you must refill the system and, more importantly, remove any trapped air. Air pockets can cause your temperature gauge to spike or result in a lack of heat from your vents.
Slowly pour your fresh 50/50 coolant mix into the degas bottle until it reaches the “Max” line. Leave the cap off and start the engine, setting your interior heater to the highest temperature and the lowest fan speed.
As the engine warms up and the thermostat opens, the coolant level in the bottle will drop. Continue to add fluid as needed while watching for bubbles rising to the surface of the reservoir.
Once the truck reaches operating temperature and the cooling fans kick on, replace the cap and take a short test drive. Check the fluid level again the following morning when the engine is completely cold and top it off if necessary.
Pro Tips for Off-Roaders and High-Mileage Trucks
If you use your F-150 for towing or hitting the trails, your cooling system works much harder than a daily commuter’s. During a 2017 ford f150 upper radiator hose replacement, take a moment to inspect the surrounding components.
Check the plastic “Y-pipe” connector found on many EcoBoost models, as these are also prone to cracking. If you see orange crust around that joint, it is best to replace it at the same time since the system is already drained.
I also recommend applying a tiny amount of silicone-based lubricant to the internal O-ring of the new quick-connect fitting. This helps it slide on smoothly and prevents the O-ring from pinching or tearing during installation.
Frequently Asked Questions About 2017 ford f150 upper radiator hose replacement
How long does it take to replace the upper radiator hose?
For a DIYer with basic tools, the job usually takes between 45 and 90 minutes. This includes the time needed to drain the coolant and properly bleed the air out of the system after installation.
Can I reuse the coolant I drained out?
It is generally recommended to use fresh coolant. However, if your coolant was recently changed and you used a clean drain pan, you can reuse it. If the fluid looks brown, cloudy, or contains debris, discard it and buy new Motorcraft Yellow or Orange.
What happens if I don’t bleed the air out of the system?
Trapped air can cause “hot spots” in the engine, leading to localized overheating. It can also cause the water pump to cavitate, which reduces its lifespan and leads to inconsistent cabin heating during the winter.
Do I need to replace the thermostat at the same time?
While not strictly necessary for a 2017 ford f150 upper radiator hose replacement, many owners choose to replace the thermostat as preventative maintenance. Since you have already drained the coolant, it only adds about 15 minutes to the total repair time.
Conclusion: Keeping Your F-150 Cool
Taking care of your truck’s cooling system is one of the best ways to ensure it reaches the 200,000-mile mark and beyond. A simple 2017 ford f150 upper radiator hose replacement is a high-impact maintenance task that protects your engine from the devastating effects of overheating.
By following the steps outlined above, you have saved yourself a trip to the dealership and gained a deeper understanding of how your Ford operates. Remember to always use the correct coolant, listen for that “click” on the quick-connect fitting, and take your time bleeding the air out.
