Coolant disappearing with no visible leak, white smoke from the exhaust, or a misfire on one cylinder of a Ford EcoBoost (the 1.5, 1.6, 2.0 and even the 3.5) is the well-known coolant-intrusion failure. The engine's open-deck design lets coolant seep into a cylinder when the block or head gasket cracks — washing the cylinder and fouling the plug. Before you pay, the first move is checking for any extended warranty, recall or settlement coverage on your engine. If you're not covered, the honest fix runs into the thousands; I diagnose it, check coverage, and flat-quote it at your home in the GTA. Call or text 647-450-0406.
Your Escape, Fusion, Edge, F-150 or other EcoBoost keeps eating coolant and you can't find a drop on the driveway. Maybe there's white smoke out the back, or a misfire on one cylinder, and the dealer said something scary like "short block" with a five-figure number. Before you panic, let me explain exactly what's happening — and the first thing I'll do is check whether Ford still owes you the fix.
I'm Fares, a mobile mechanic in Mississauga, and EcoBoost coolant loss is a regular call. The F-150 EcoBoost is everywhere up here, and the smaller 1.5/1.6/2.0 engines are in a ton of Escapes and Fusions. This failure is documented enough that Ford issued service bulletins and warranty extensions on several of these.
Many EcoBoost engines use an open-deck block — the cylinders aren't fully tied into the block casting around the top, which is lighter and good for cooling but structurally weaker. Under boost and heat cycling, the area around a cylinder can crack, or the head gasket fails locally, and coolant seeps into the combustion chamber. That's "coolant intrusion." The coolant gets burned off, which is why you lose it with no puddle, and it washes the cylinder and fouls that plug, causing a misfire. The white smoke is coolant going out the exhaust.
The pattern varies by engine: the small 1.5, 1.6 and 2.0 (Escape, Fusion, Edge, MKC) are the classic intrusion engines, and on those Ford's official repair is often a short block. The 3.5 EcoBoost (F-150) more commonly has a coolant issue tied to the cylinder head/gasket. Either way the symptom set is the same, and either way coverage is the first question.
I confirm it: a combustion-gas (block) test on the coolant shows exhaust gases in the system, pulling the suspect plug shows the tell-tale clean/wet cylinder, and a cooling-system pressure test rules out a simple external leak. And I run your VIN for any Ford extended warranty, customer-satisfaction program or class-action settlement. Several of these engines had coverage extended — if yours qualifies, the dealer does the repair and you shouldn't pay me. I'll tell you that straight.
If you've fallen outside coverage and it's confirmed, the fix depends on the engine. On the small EcoBoosts with a cracked cylinder, the proper repair is a short block (the lower end) with your good parts transferred over. On a 3.5 with a head-gasket/head coolant issue, it can be a head and gasket job. I'll tell you exactly which after diagnosis — no guessing, no quoting a short block when a head job will do.
Real numbers, for an out-of-pocket job. The exact figure depends on your engine and which repair it needs, but here's the honest GTA range.
Dealer, out of pocket: typically $6,000–$10,000 for a short block
At your place with Cars With Fares: usually $4,200–$5,500 for a quality short-block job, or less for a head/gasket repair, flat-quoted before any work.
That's parts and labour as one number. What swings it: short block vs. head job, the 3.5 (F-150) vs. the small fours, and parts availability.
It lands under the dealer because there's no service-department overhead on top, not because anything's skipped. The savings is the byproduct; you're paying for the right repair done once.
An engine repair sounds like a shop-only job, but with proper support I do it at your place, and you're standing right there to see the work. On a five-figure-class repair where the dealer's first word was "short block," being able to watch the old unit come out and the new one go in — and getting a flat number that doesn't move — is exactly the trust you want. No car vanishing for a week, no bill that grew.
If it's smoking, misfiring badly, or overheating: stop driving it. Coolant in a cylinder hydro-locks risk and washes the bore — every drive makes the damage worse and can take out the catalytic converter too. And the bigger reason: if you might be covered, you don't want to drive it into a state that complicates the claim. Park it, let's confirm the failure and check your coverage first. If Ford owes you the fix, you'd hate to lose that by running it.
Tell me your year, model and engine and what's happening — I'll tell you if it's coolant intrusion, help you check coverage, and quote the real fix if Ford no longer owes you one.
Get My Quote →Several EcoBoost engines (the 1.5, 1.6, 2.0 and some 3.5) had coverage extended through Ford warranty extensions, customer-satisfaction programs or class-action settlements for the coolant-intrusion failure. The first step is running your VIN and engine against those programs and calling the dealer. If you're covered, the dealer does the repair and you shouldn't pay out of pocket. I always check this first — there's no reason to pay for something Ford owes you.
If you're outside coverage, a quality short-block repair on a small EcoBoost runs roughly $4,200–$5,500 done at your home, versus $6,000–$10,000 at a dealer. A 3.5 EcoBoost with a head-gasket/head coolant issue can be less if it only needs a head and gasket rather than a short block. It depends on which repair your engine actually needs and parts availability. I diagnose it precisely and flat-quote before any work — and only after confirming you're not covered.
The classic signs are coolant disappearing over weeks with no external leak you can find, white smoke or steam from the exhaust (often under load) with a sweet smell, and a misfire on one specific cylinder, where pulling that plug shows a suspiciously clean, steam-washed cylinder. Some cars also overheat or the overflow bubbles as combustion gases get into the coolant. A combustion-gas test on the coolant confirms it.
Yes — with proper support a short-block or head repair is doable in your driveway across Mississauga and the GTA, and you get to watch it happen instead of losing the truck or car to a shop for a week. But on an EcoBoost coolant case the real first step is confirming the failure and checking your Ford coverage, because if you qualify, the right answer is the dealer's covered repair, not my bill.
