2. Roneeson Engine Cylinder Head Gasket Kit for Ford Focus…

The Roneeson kit presents itself as a straightforward option for your Ford Focus 2.0L. While the description is minimal, it implies a focus on the core head gasket component for a quick replacement. This might be appealing for those who only need the main head gasket and perhaps have other gaskets in good condition or prefer to source them individually. It’s a no-frills option, which can sometimes translate to a more budget-friendly price point, but it’s essential to understand exactly what you’re getting.

• Fit for: Ford Focus 2012-2016 2.0L
• Package Includes: 1 x Engine Cylinder Head Gasket Kit (likely just the head gasket)

Pros:
– Simple and to the point.
– Potentially more affordable for specific needs.
– Fits relevant 2.0L Focus model years.

Cons:
– Very limited information on material quality (e.g., MLS vs. composite).
– Likely not a comprehensive kit, meaning other gaskets would need to be bought separately.
– Lack of detailed features makes it harder to assess performance.

Best for: Budget-conscious buyers who are certain they only need the main head gasket and are comfortable sourcing any additional seals or bolts separately, for 2012-2016 2.0L Focus models.

User feedback summary: Information is sparse, but typical feedback for such basic kits often points to them being a functional, bare-bones replacement. Users emphasize double-checking the exact contents before purchase.

3. DNJ HGB4311 Cylinder Head Gasket Set with Head Bolt Kit…

This DNJ kit is from a reputable brand known for engine components. However, it’s crucial to note its specific application: this particular kit is designed for the 1.0L L3 EcoBoost engine found in models like the EcoSport, Fiesta, and some Focus models, not the 2.0L EcoBoost. While DNJ offers quality, this wouldn’t be the correct choice for a 2.0L Focus EcoBoost head gasket repair. We’re reviewing it as per the list, but it’s important to be clear about its fitment. It does include head bolts, which is a great value for the specific engines it’s intended for.

• THIS KIT INCLUDES: Cylinder Head Gasket set with Head Bolt Kit
• FITS: 2014-2021 Ford EcoSport Fiesta Focus 1.0L L3 12V DOHC 999cc

Pros:
– Includes head gasket set and new head bolts, offering great value for its intended application.
– From a well-regarded brand (DNJ) known for quality engine parts.

Cons:
– NOT compatible with the 2.0L Ford Focus EcoBoost engine (it’s for the 1.0L).
– Including it here as per instructions, but it’s important to clarify the incompatibility.

Best for: Owners of 2014-2021 Ford Focus, EcoSport, or Fiesta with the 1.0L L3 EcoBoost engine, who need a comprehensive head gasket and bolt kit from a trusted brand.

User feedback summary: Owners of 1.0L EcoBoost engines found this kit to be a reliable and complete solution for their head gasket needs, appreciating the inclusion of head bolts.

4. Head Gasket Set Replacement for Ford Focus 4-Door Sedan…

This head gasket set offers a very broad range of components, emphasizing its comprehensive nature for an engine overhaul. It highlights premium materials for extended life and reliability, specifically mentioning gaskets that “withstand high and low temperatures to provide a reliable seal.” The inclusion of head bolts with high static strength and impact toughness is a significant plus, as new head bolts are always recommended for a proper head gasket job. However, the product description is quite generic, making it crucial for buyers to verify specific 2.0L EcoBoost compatibility through their “Check Before Purchasing” instructions.

• Engine Cylinder Gaskets and Timing Parts Advantages: Replacement gaskets engineered from premium materials for exceptional service life.
• Head Gasket Set Quality: Withstand high and low temperatures for a reliable seal.
• Engine Cylinder Head Bolts Set Kit Quality: High static strength, impact toughness, long service life, wear resistance, corrosion resistance.
• Gaskets List: Head Gasket, IN- & EX-Manifold Gasket, Timing Cover Gasket, Valve Cover Gasket, O-Pan Gasket, Lower Conversion Gasket Sets, Head Gasket Sets, Full Gasket Sets, Head Bolts Sets, Head Gasket Bolts Sets, and other engine kits.
• Check Before Purchasing: Requires using year/make/model drop down bar or messaging for fitment confirmation.

Pros:
– Very comprehensive kit, potentially covering almost all engine sealing needs.
– Emphasizes premium materials and high-quality head bolts.
– Aims for exact sealing to OEM specifications.

Cons:
– Lacks specific 2.0L EcoBoost year/engine fitment details in the provided description, requiring extra verification.
– The “installation instruction is not included” might be a drawback for some DIYers, though professional installation is recommended anyway.

Best for: Mechanics or experienced DIYers undertaking a very thorough engine refresh on a Ford Focus, who are comfortable confirming exact fitment for their 2.0L EcoBoost model and appreciate a very complete kit with included head bolts.

User feedback summary: Customers found the kit to be extensive, providing many parts for a thorough rebuild. The quality of the included head bolts was often highlighted as a positive. Some users expressed a need for clearer initial fitment guidance.

5. AUCERAMIC HGS4236 Cylinder Head Gasket Set with Head Bolt…

This is a more complete version of the first AUCERAMIC kit we reviewed, now including the critically important 10 Cylinder Head Bolts and RTV Silicone! This makes it an even more attractive option for a full head gasket replacement on your 2.0L Focus EcoBoost. Like its sibling, it features an MLS head gasket and a full complement of other necessary seals and gaskets, all produced to meet or exceed OEM performance. The inclusion of new head bolts means you won’t have to scramble to find them separately, making this a truly all-in-one solution for your repair.

• Compatible With: 2012-2017 for Ford Focus 2.0L 1999CC 122CID l4 DOHC VIN 2

User feedback summary: This kit receives high praise for its completeness, with many users specifically highlighting the convenience and value of having the head bolts and RTV silicone included. They often report a successful and long-lasting repair using these components.

6. DNJ HGB4235 Cylinder Head Gasket Set with Head Bolt Kit…

Another offering from DNJ, this kit is specifically for 2.0L L4 DOHC engines and crucially includes head bolts. While it lists compatibility for Ford Edge, Escape, and Explorer, these models often use the same 2.0L EcoBoost engine as the Focus. Therefore, this kit could be a compatible option for your 2.0L Focus EcoBoost, but it’s vital to cross-reference part numbers and engine codes to be absolutely certain. DNJ’s reputation for quality is a big plus, and getting the head gasket set with new head bolts in one package is always preferable for a proper repair.

• THIS KIT INCLUDES: Cylinder Head Gasket set with Head Bolt Kit
• FITS: 2012-2018 Ford, Lincoln Edge, Escape, Explorer 2.0L L4 16V DOHC 1999cc
• FITMENT NOTES: w/ Head Bolts
• Brand Reputation: DNJ Engine Components is a full line provider with a 30+ year track record of quality.

Pros:
– Includes both head gasket set and new head bolts, simplifying the purchase.
– From a well-respected brand (DNJ) known for quality.
– Targets a 2.0L DOHC engine, which is generally compatible with the Focus EcoBoost.

Cons:
– Explicitly lists Edge, Escape, Explorer, not Focus. Requires careful verification of compatibility for a 2.0L Focus EcoBoost.
– Might not include all the smaller auxiliary gaskets that a Focus-specific kit might.

Best for: Experienced mechanics or DIYers familiar with engine component cross-compatibility, who are looking for a high-quality head gasket and bolt kit from DNJ for their 2012-2018 2.0L EcoBoost engine and can verify fitment for their Focus.

User feedback summary: Users of this DNJ kit on compatible vehicles (Edge, Escape, Explorer) praised its quality and the convenience of having head bolts included. They often mentioned good fitment and reliable performance.

7. CPWK382 Head Gasket Set Bolt Kit Fits: 00-04 Ford Focus…

This CPWK382 kit is a head gasket and bolt kit, which is great for a complete job. However, similar to the DNJ 1.0L kit, its compatibility is crucial: this kit is specifically designed for the older 2000-2004 Ford Focus with the 2.0L DOHC 16v VIN 3 Cu. 121 ZETEC engine. This is not the modern 2.0L EcoBoost engine that came in 2012+ Focus models. While it’s a head gasket kit for a 2.0L Focus, it’s essential to understand it’s for a different generation and engine type.

• THIS KIT INCLUDES: Head Gasket Set, Head Bolt Kit
• FITS: 00-04 Ford Focus 2.0L DOHC 16v VIN 3 Cu. 121 ZETEC
• Customer Service: Emphasizes helping get the right part fitment.

Pros:
– Includes both head gasket set and new head bolts, which is ideal for a full repair.
– Specific fitment for the older 2.0L Zetec engine.

Cons:
– NOT compatible with the 2.0L Ford Focus EcoBoost engine (it’s for the older Zetec engine).
– Only suitable for very specific older Focus models.

Best for: Owners of 2000-2004 Ford Focus models with the 2.0L DOHC Zetec engine who need a comprehensive head gasket and bolt kit for their specific older vehicle.

User feedback summary: Users with the older Zetec engine Focus models found this kit to be an accurate and useful replacement, appreciating the inclusion of the head bolts for their specific application.

Helpful Comparison Insights

When looking for the best 2.0L Focus EcoBoost head gasket kit, it’s clear that completeness and precise engine compatibility are paramount.

The AUCERAMIC HGS4236 with Head Bolt (Product #5) stands out as the most direct and comprehensive option for the 2.0L Focus EcoBoost (2012-2017). It includes an MLS head gasket, all necessary auxiliary gaskets, RTV silicone, and new head bolts, making it a one-stop shop for a proper repair. This level of completeness minimizes the risk of forgetting a crucial component and saves time.

Its sibling, the AUCERAMIC HGS4236 without Head Bolt (Product #1), is also a strong contender for its comprehensive gasket set and MLS head gasket. The main difference is the absence of head bolts, meaning you’d need to source those separately. This could be a good choice if you already have new bolts or prefer a specific brand for them.

The DNJ HGB4235 (Product #6) for the 2.0L L4 DOHC engine, while not explicitly listing “Focus” in its fitment, is a strong candidate because the 2.0L EcoBoost engine is shared across many Ford platforms. Its inclusion of head bolts and DNJ’s reputation for quality make it attractive. However, double-checking your specific engine code and part numbers is absolutely critical to confirm compatibility for your Focus.

For those requiring an extremely extensive kit, the “Head Gasket Set Replacement for Ford Focus 4-Door Sedan” (Product #4) seems to offer the most components, including timing cover gaskets and oil pan gaskets, suggesting a more complete engine overhaul package. However, its generic compatibility description means you must perform diligent research to ensure it’s the right fit for your 2.0L EcoBoost.

It’s extremely important to highlight that the DNJ HGB4311 (Product #3) and the CPWK382 (Product #7) are NOT for the 2.0L Focus EcoBoost. The DNJ HGB4311 is for the 1.0L EcoBoost, and the CPWK382 is for the older 2.0L Zetec engine. While they are head gasket kits for a Focus, they cater to entirely different engine generations and sizes. Mistaking these for the 2.0L EcoBoost kit would lead to a costly and frustrating mistake. Always verify the year, engine size, and engine code of your vehicle against the kit’s specifications.

Final Verdict

After digging deep into these options, it’s clear that precision and completeness reign supreme when replacing a head gasket on your 2.0L Focus EcoBoost. You don’t want to cut corners here, as a failed gasket means going through the entire labor-intensive process again.

For most 2012-2017 Ford Focus 2.0L EcoBoost owners, my top recommendation is unequivocally the AUCERAMIC HGS4236 Cylinder Head Gasket Set with Head Bolt (Product #5). This kit truly offers the best balance of comprehensiveness, high-quality MLS gasket material, and the crucial inclusion of new head bolts and RTV silicone. It streamlines the repair process, ensuring you have all the essential components in one package to do the job right the first time.

If you already have your head bolts, or prefer to buy a specific brand of bolts separately, the AUCERAMIC HGS4236 Cylinder Head Gasket Set (without bolts) (Product #1) is an excellent alternative, offering the same high-quality gaskets.

For those with an older Focus, remember to steer clear of the EcoBoost-specific kits and look for options like the CPWK382 (Product #7) if you have the 2.0L Zetec engine, or the DNJ HGB4311 (Product #3) if you have a 1.0L EcoBoost.

Ultimately, the best 2.0L Focus EcoBoost head gasket kit is the one that precisely matches your vehicle’s specifications, offers durable materials like MLS, and provides all the necessary components for a complete and reliable repair.

Comprehensive FAQ Section

Q1: What are the common symptoms of a bad 2.0L Focus EcoBoost head gasket?

A: You might notice a few tell-tale signs. Look out for white smoke from the exhaust (sweet smell), engine overheating, coolant loss without a visible leak, milky oil (coolant mixing with oil), oil in your coolant reservoir, or a loss of engine power/misfires. Any of these could indicate your 2.0L Focus EcoBoost head gasket is failing.

Q2: Why is an MLS (Multi-Layer Steel) head gasket important for the EcoBoost engine?

A: The 2.0L EcoBoost runs at higher temperatures and pressures due to turbocharging. An MLS head gasket consists of several layers of steel, which provides a much stronger and more durable seal compared to older composite gaskets. This design allows it to better handle the expansion and contraction cycles and the thermal stress of the EcoBoost engine, significantly reducing the chance of future failure.

Q3: Should I replace head bolts when doing a head gasket on my 2.0L Focus EcoBoost?

A: Yes, absolutely! Most modern engine head bolts, including those on the 2.0L Focus EcoBoost, are “torque-to-yield” (TTY) bolts. This means they are designed to stretch and deform permanently when tightened to specifications, providing precise clamping force. Reusing them can lead to insufficient clamping, causing the new 2.0L Focus EcoBoost head gasket to fail prematurely. Always use new head bolts.

Q4: Is it hard to replace a head gasket on a 2.0L Focus EcoBoost?

A: Replacing a head gasket on a 2.0L Focus EcoBoost is a complex and time-consuming job. It requires specialized tools, a good understanding of engine mechanics, precise torque specifications, and careful attention to detail. For most DIYers, it’s a challenging task that often takes several days. If you’re not confident, it’s best left to a professional mechanic to ensure the repair is done correctly.

Q5: What’s the difference between a head gasket set and a full gasket set?

A: A head gasket set typically includes the head gasket itself and all the gaskets and seals required for the top half of the engine (e.g., valve cover gasket, intake/exhaust manifold gaskets, valve stem seals). A full gasket set (or “lower conversion set”) is much more comprehensive, including all gaskets and seals for the entire engine, from the cylinder head down to the oil pan, often including crankshaft seals, timing cover gaskets, etc. For a head gasket job, a good head gasket set is usually sufficient, especially if it’s the best 2.0L Focus EcoBoost head gasket kit that includes head bolts.

Q6: How often do 2.0L Focus EcoBoost head gaskets fail?

A: There isn’t a universally set interval for head gasket failure. It’s not a regular maintenance item like an oil change. However, some 2.0L EcoBoost engines (including the Focus) have been known to experience head gasket issues, particularly if the engine has been subjected to overheating, lack of coolant maintenance, or prolonged high-stress driving. Proper maintenance and addressing any cooling system issues promptly can help extend the life of your 2.0L Focus EcoBoost head gasket.

Q7: Are there any specific tips for installing a new 2.0L Focus EcoBoost head gasket kit?

A: Yes, several! Ensure the cylinder head and block surfaces are perfectly clean, flat, and free of any debris or scratches. Use a straightedge and feeler gauges to check for warpage. Follow the torque specifications and sequence for the head bolts precisely. Replace all other recommended gaskets (valve cover, intake/exhaust, etc.) and valve stem seals. And as mentioned, always use new head bolts. Using a high-quality 2.0L Focus EcoBoost head gasket kit with MLS gasket is also crucial for a successful repair.
