We will cover everything from initial diagnosis and specialized timing tools to the final torque sequence that ensures a permanent seal. Let’s dive into the details and get your Escape back on the road or the trail.
Signs You Need a 2017 Ford Escape Head Gasket Replacement
Before you start tearing into the engine bay, you must confirm that the head gasket is actually the culprit. The 2017 Ford Escape, particularly those with the 1.5L EcoBoost, is known for a specific coolant intrusion issue where fluid enters the combustion chamber.
One of the most obvious signs is a persistent misfire on cold starts, often accompanied by a “Check Engine” light for codes P0301 through P0304. This happens because coolant leaks into the cylinders overnight, fouling the spark plugs.
You should also check your oil dipstick for a milky, “chocolate milkshake” appearance, which indicates that coolant and oil are mixing. If you see bubbles in the coolant overflow tank while the engine is running, combustion gases are likely leaking past the gasket.
Using a Block Test Kit
To be 100% certain, I recommend using a chemical block tester, which detects CO2 in the cooling system. If the blue fluid turns yellow or green, you have a confirmed leak.
A cooling system pressure test is another great diagnostic tool; it allows you to see if the system holds pressure or if it drops, indicating an internal leak. Always diagnose twice and cut once to avoid unnecessary labor.
Essential Tools and Parts for the Job
This is not a repair you can finish with a basic socket set from a big-box store. Because the EcoBoost is an interference engine with Variable Cam Timing (VCT), you need specific hardware to keep everything synchronized.
You will absolutely need a Ford-specific camshaft alignment tool kit to lock the cams and crankshaft in place. Without this, you risk bent valves and total engine failure the moment you turn the key.
- Torque Wrench: A high-quality digital or click-type wrench is mandatory for the head bolts.
- TTY Bolts: Torque-to-Yield bolts are one-time use only; never reuse the old head bolts.
- Gasket Set: Purchase a complete upper head set that includes intake and exhaust manifold gaskets.
- Shop Vac and Scrapers: For cleaning the block surface without dropping debris into the oil passages.
Selecting the Right Gasket
Always opt for a Multi-Layer Steel (MLS) gasket from a reputable brand or an OEM Ford replacement. These are designed to handle the high cylinder pressures of turbocharged engines better than cheaper composite alternatives.
Don’t forget to have fresh Motorcraft Orange or the newer Yellow coolant on hand, along with a high-quality synthetic oil and a new filter for the post-repair flush.
Detailed Step-by-Step 2017 Ford Escape Head Gasket Replacement
Start by disconnecting the negative battery terminal and draining the cooling system and engine oil. You will need to remove the cowl panel near the windshield to gain enough clearance to work on the back of the engine.
Remove the air intake assembly, the battery box, and the various vacuum lines crisscrossing the valve cover. Label every electrical connector with masking tape to make reassembly much faster and less stressful.
Next, you must remove the Intake Manifold and the Turbocharger heat shields. On the 2.0L models, the turbo is bolted to the exhaust manifold, which can be heavy and awkward to maneuver in the tight engine bay.
Setting the Timing
Rotate the engine to Top Dead Center (TDC) on cylinder number one before removing the timing belt or chain. Insert your timing pegs and alignment bar to ensure the cams do not move once the tension is released.
Once the timing components are clear, you can begin loosening the cylinder head bolts in the reverse order of the tightening sequence. This prevents the head from warping as the clamping pressure is released.
Carefully lift the cylinder head off the block; if it feels stuck, double-check for any missed bolts or brackets. Never use a pry bar against the mating surfaces, as a single scratch can cause a permanent leak.
Inspecting the Block and Cylinder Head
Once the head is off, the real work begins with cleaning and inspection. When performing a 2017 ford escape head gasket replacement, inspecting the cylinder head for flatness is non-negotiable.
Use a precision straightedge and a feeler gauge to check for warping across the deck of the head and the engine block. If the head is warped more than 0.002 inches, it must be sent to a machine shop for resurfacing.
Pay close attention to the areas between the cylinders, as this is where the 2017 EcoBoost blocks often develop small cracks. If you see any hairline fractures in the block itself, a new gasket will not fix the problem.
Cleaning the Mating Surfaces
Use a plastic scraper or a brass brush to remove old gasket material; avoid using steel wool or abrasive “cookie” discs on a die grinder. These can remove aluminum material and create low spots that the new gasket cannot seal.
Wipe the surfaces down with brake cleaner or denatured alcohol to remove every trace of oil and grease. The surfaces should be “squeaky clean” and dry before the new gasket is laid down.
Reassembly and Critical Torque Specs
Place the new gasket onto the dowel pins on the engine block, ensuring it is oriented correctly (most are marked “Top” or “Front”). Carefully lower the cylinder head onto the block without sliding it around.
Install your brand-new Torque-to-Yield (TTY) bolts by hand to ensure they are not cross-threaded. You must follow the Ford service manual’s specific multi-stage torque sequence to the letter.
- Stage 1: Tighten all bolts to the initial torque spec (usually around 5-10 Nm) in the specified sequence.
- Stage 2: Tighten all bolts to the secondary torque spec (often around 40 Nm).
- Stage 3: Use a torque angle gauge to turn each bolt an additional 90 or 180 degrees as specified.
This “stretch” method ensures that the bolts provide a constant, even clamping force across the entire gasket. Skipping the angle-torque step is the number one reason for premature gasket failure after a repair.
Reinstall the timing components, ensuring your alignment tools still fit perfectly. Rotate the engine by hand two full revolutions to verify there is no mechanical interference before putting the valve cover back on.
Frequently Asked Questions About 2017 Ford Escape Head Gasket Replacement
How long does a 2017 ford escape head gasket replacement take?
For an experienced DIYer, this job typically takes between 12 and 18 hours of active labor. It is best to spread the work over a full weekend to avoid rushing the cleaning and timing stages.
Is it worth replacing the head gasket or should I get a new engine?
If the block is cracked (common in the 1.5L EcoBoost), a gasket replacement will fail. However, if the block is healthy and the head is just slightly warped, a gasket replacement is much cheaper than a $6,000 engine swap.
Do I need to change the water pump during this repair?
Yes, it is highly recommended. Since you already have the timing system disassembled, replacing the water pump and timing belt/chain adds very little labor but provides great peace of mind.
Can I use head gasket sealer fluid instead?
No, sealer fluids are a temporary “band-aid” and often clog the heater core and radiator. In a turbocharged engine like the Escape’s, these sealers rarely hold up against high boost pressures.
Final Thoughts on Your Engine Repair
Completing your 2017 ford escape head gasket replacement successfully is a massive achievement that saves you thousands in professional labor. It requires precision, the right specialized tools, and a commitment to cleanliness.
Remember to double-check your timing marks and never reuse TTY bolts. Once the engine is back together, perform a “break-in” oil change after the first 50 miles to remove any assembly lube or debris that entered the system.
Take your time, follow the torque sequences exactly, and don’t be afraid to consult a professional if you find cracks in the engine block. Stay safe, work carefully, and enjoy the satisfaction of a job well done!
