Ford 3.5 EcoBoost head gasket replacement cost
The 3.5 EcoBoost is in roughly one in four F-150s on the road in 2026. Repair runs $3,000 to $5,500, not the $1,800 average for a regular V6, because every hour reaching the head costs you. Here is exactly where the extra money goes.
Quick answer
$3,000 to $5,500 at an independent. $4,500 to $7,000 at a Ford dealer.
A Ford 3.5 EcoBoost head gasket job is roughly double the labor hours of a naturally-aspirated V6, because reaching the cylinder heads on a twin-turbo engine means removing both turbochargers, both intercooler hose runs, both downpipes, the entire intake manifold, the upper radiator hose assembly, and on F-150s the cab-side wiring shroud. The gasket itself is the cheapest part of the bill. Twin heads also mean double the machine shop time and double the head-bolt cost. Expect 14 to 22 billable labor hours depending on the chassis (transverse Flex and Edge are at the high end of the range because the rear bank is harder to access against the firewall than on a longitudinally-mounted F-150).
The good news: 3.5 EcoBoost head gasket failure is genuinely uncommon when the engine has been maintained. Most of the search traffic on this query is from truck owners who have seen white smoke, milky oil, or rising temperatures and want to know if they are looking at a $1,500 fix or a $5,000 one. The answer for an EcoBoost is almost always closer to $5,000 than $1,500, so this page exists to set expectations honestly rather than quote a generic V6 number.
By chassis and year
What you pay by truck or chassis
| Vehicle | Engine | Repair cost | Note |
|---|---|---|---|
| F-150 (2011-2016, 1st gen) | 3.5L EcoBoost (2nd-gen turbos) | $3,200 - $4,800 | Most common application. Carbon-deposit and intercooler-condensation companion issues. |
| F-150 (2017-2020, 2nd gen) | 3.5L EcoBoost (revised heads) | $3,500 - $5,200 | Improved port-injection helped carbon; HG repair largely unchanged. |
| F-150 (2021+, 3rd gen) | 3.5L EcoBoost | $3,800 - $5,500 | Newer trucks usually still under powertrain warranty (5yr / 60k). |
| F-150 Raptor (2017-2020) | 3.5L EcoBoost High Output | $4,500 - $7,000 | Higher-output build. OEM-only parts. Specialist shop strongly recommended. |
| Expedition (2018+) | 3.5L EcoBoost | $3,500 - $5,500 | Body-on-frame SUV. Engine bay access slightly easier than F-150. |
| Navigator (2018+) | 3.5L EcoBoost | $3,800 - $6,000 | Lincoln dealer parts premium. Independent specialist saves 25-35%. |
| Flex EcoBoost (2010-2019) | 3.5L EcoBoost (transverse) | $3,500 - $5,500 | Transverse mounting in the Flex makes rear-bank access harder than F-150. |
| Edge Sport (2010-2019) | 3.5L EcoBoost (transverse) | $3,500 - $5,500 | Same transverse layout as Flex. Rear bank labor adds 1-2 hours. |
| Taurus SHO (2010-2019) | 3.5L EcoBoost (transverse) | $3,800 - $5,800 | Performance sedan trim. Cooling-system complexity higher than F-150. |
Ranges reflect 2026 US independent-shop pricing in mid-rate metros ($115 to $145 per hour). Add roughly 20 to 35% for dealer pricing. California, New York, and Hawaii run 15 to 25% above these ranges (see cost by state).
Where the money actually goes
The line-item breakdown
A quote that does not break itemise these lines is hiding something, almost always the machine shop fee or the head bolts. If a shop quotes you a flat $3,800 and refuses to show the parts versus labor split, walk.
Head gasket set (both heads)
Two heads on a V6. Felpro and Mahle both make full-engine kits; OEM Motorcraft set runs $350-$500.
Labor, 14 to 22 hours
Twin turbos, intercoolers, and downpipes all come off. Roughly double a Civic.
Machine shop: resurface both heads
Both heads pulled, magnafluxed, decked, and pressure-tested. Twin heads = double the shop fee.
Head bolts (torque-to-yield, both heads)
Single-use. Both heads need fresh bolts.
Coolant + Motorcraft 5W-30 + gasket kit
EcoBoost needs Motorcraft Gold coolant. 6+ quarts of oil.
Intercooler service (paired job)
Drain condensation, replace clamps. Recommended while everything is off.
Spark plugs (8 plugs, recommended)
Buried under intake. Replace while accessible. Iridium OEM only on EcoBoost.
Subtotal: roughly $2,320 to $5,330 in parts and labor. Add diagnostic ($100 to $250) if not waived. Sources: Felpro, Mahle, and Motorcraft public part listings; BLS automotive technician wage data; Mitchell ProDemand labor times for OEM 11AB/11AC heads.
What makes EcoBoost different
Four reasons EcoBoost head gaskets cost what they do
Each cylinder bank has its own turbocharger bolted to the exhaust manifold. Removing the heads means removing both turbos, both downpipes, both wastegate actuators, and both oil-feed and oil-return lines. Roughly 4 to 6 hours of additional labor before you have even touched the heads. The 5.4 Triton 3V skips this entirely because it is naturally aspirated.
Air-to-air intercooler with charge-pipes routed across the engine bay. The intercooler condensation issue on 2011 to 2016 F-150s sometimes leads owners to misdiagnose HG failure (white exhaust steam in cold weather can be condensate burning off, not coolant). A competent shop confirms HG with a block test before pulling the engine apart.
Direct-injection engines accumulate carbon on the intake valves because there is no fuel washing the valves clean. When the heads are off, having the valves walnut-blasted ($300 to $600 add-on) restores roughly 10 to 25 horsepower lost to carbon and is a logical pairing. The 2017+ trucks with port-and-direct dual injection mostly solved the carbon problem.
Standard V6 jobs send one head out for resurfacing. EcoBoost ships both heads. Most shops outsource to a local machine shop at $200 to $400 per head plus magnaflux and pressure-test ($60 to $120 per head). Round-trip turnaround is 3 to 7 days, which is why the truck is in the bay for 1 to 2 weeks total.
Before you spend $5,000
Confirm it is actually the head gasket
EcoBoost trucks have at least four conditions that present like a blown head gasket but are not. Spend the $50 to $150 on a confirmatory block test before authorising the teardown, because Ford 3.5 EcoBoost teardowns are sometimes how a $1,500 problem becomes a $5,000 one.
Intercooler condensation
Cold-weather white steam from the tailpipe that goes away once the truck warms up. Not a head gasket. Drain the intercooler ($30 to $80) and reroute the charge-air drain.
Bad PCV valve or breather hose
Excessive oil consumption, light smoke, sometimes oil pooling in the intake. Replace PCV and check the breather ($60 to $200) before assuming HG.
Cracked exhaust manifold
Ticking on cold-start that fades as the metal expands. Smoke if oil drips on the exhaust. $400 to $900 to replace, not $4,500.
Carbon-loaded valves
Misfires, rough idle, P0301 to P0306 codes. Carbon, not HG. Walnut blast ($300 to $600) restores compression on the affected cylinder.

Who should do the work
Ford dealer, EcoBoost-fluent independent, or general shop
The labor hours on a 3.5 EcoBoost are too many to give to a generalist. Find an EcoBoost specialist or use the dealer. Generalists who quote $2,200 are either underbidding (and will return for change orders) or have never done one.
Ford Dealer
$4,500 - $7,000
Right call if truck is under powertrain warranty (5yr / 60k), if a Ford TSB applies, or if a software update is part of the fix. Otherwise a premium for the same gasket.
EcoBoost Independent
$3,000 - $5,500
The sweet spot. Look for shops advertising EcoBoost and diesel work, machine shop in-house or partnered, ASE-certified Master Technician on payroll.
General Shop
Avoid
A general mechanic who has done two Civics this year will struggle with the turbo plumbing. The bill ends up the same as the specialist but the timeline doubles and the failure rate rises.

The fix-or-trade math
Is a $4,000 repair worth it on your F-150?
Trucks hold value much better than sedans, which is why HG repair on an F-150 makes sense at higher absolute dollar amounts. A 2016 F-150 EcoBoost with 130,000 miles is still a $14,000 to $19,000 truck in clean condition in 2026. A $4,000 head gasket repair is 21 to 29% of value, comfortably in the "fix it" zone.
The repair becomes borderline on older trucks with high mileage and a list of looming repairs. A 2011 F-150 with 220,000 miles, worn ball joints, and a tired transmission at $7,000 of value puts a $4,000 HG repair at 57% of value. That is the borderline band where the rest of the truck has to be in genuinely good shape to justify the cost. If the body has rust or the transmission slips, you are propping up a money pit.
Run your specific numbers through the fix-or-total decision framework. The 50% rule is the standard cutoff but trucks can extend to 55 to 60% because of the resale floor.
Frequently asked
Common 3.5 EcoBoost head gasket questions
Is 3.5 EcoBoost head gasket failure common?+
Less common than the 5.4 Triton 3V, more common than a Honda or Toyota V6. The bigger 3.5 EcoBoost concerns are carbon buildup on intake valves (because of direct injection with no port-injection assist on 2011-2016 models) and intercooler condensation, both of which can mimic HG symptoms and confuse diagnosis. Verify HG with a block test or coolant pressure test before authorising the repair.
Why does the EcoBoost cost so much more than a regular 3.5 V6?+
Twin turbochargers, two intercoolers, twin downpipes, twin wastegate actuators, all of which come off to reach the heads. The standard Ford Duratec 3.5 is roughly 8 to 12 hours of labor; the 3.5 EcoBoost is 14 to 22 hours. Parts cost is similar but labor roughly doubles. Add the intercooler-service-while-it-is-open and you arrive at $3,000 to $5,500.
Should I replace the turbochargers while the engine is apart?+
Only if they show shaft play, oil leakage, or have over 150,000 miles. Replacing both turbos out of preventative caution adds $1,800 to $3,500 to the bill. If the truck is at 90,000 miles and turbos spool cleanly, leave them. If you are already at 180,000 and replacing the heads, the labor overlap makes a turbo refresh more rational.
Does Ford dealer pricing differ much from an independent?+
Yes. Ford dealer rates run $145 to $200 per hour in most metros. Specialist independent diesel-and-EcoBoost shops run $110 to $145. On a 16-hour job that is a difference of $560 to $1,000. The dealer is worth it when the truck is under powertrain warranty (5yr / 60k miles), when a TSB applies, or when a software update is part of the fix. Otherwise an EcoBoost-fluent independent is the right call.
What other repairs should I budget for at the same time?+
Cam phasers if the truck is over 100,000 miles ($600 to $1,200 in parts; labor already largely paid). VCT solenoids ($150 to $300 part, minimal added labor). Spark plugs (always). Intercooler clamps and hoses ($100 to $250). Engine coolant flush is included in the gasket job. If the timing chain is original at over 150,000 miles, a guide-and-tensioner refresh runs $400 to $900 extra and is logical now.
Will an EcoBoost run on stop-leak sealer?+
Almost never with a useful outcome. Direct-injection turbocharged engines run cylinder pressures and coolant pressures high enough that sealer products designed for naturally-aspirated 4-cylinders simply blow back out. The 50/50 success-rate on a Honda Civic drops to about 10 to 15% on a 3.5 EcoBoost. Treat sealer as a $60 long-shot before you commit to the $3,500 job, not as a real fix.
