How much does it cost to replace a head gasket on a 2010 Subaru Forester?

The typical cost is in the ballpark of about $1,500 to $3,500, with higher quotes if additional work or machine work is needed. This range reflects common labor rates across the United States and variations in what the repair includes.

For a 2010 Subaru Forester, which uses the 2.5-liter EJ-series engine, head gasket replacement is a labor-intensive job that can involve more than just changing gaskets. Prices vary by region, shop, and how comprehensive the service is. Expect quotes to reflect whether your estimate covers timing components, water pumps, coolant flushes, head resurfacing or machining, and any engine removal required to access the cylinder head.

What a head gasket replacement typically involves

Replacing a head gasket on a Subaru Forester is a major repair. The work generally includes removing parts to access the cylinder head, inspecting the head for warping, replacing the head gasket, and reinstalling the timing components along with several ancillary parts. The following items are commonly included in a complete job.

• Removal and reinstallation of the cylinder head and associated components


• Head gasket kit (gaskets, seals, o-rings)


• Hydraulic head bolts and related fasteners


• Timing belt/chain kit and tensioners if applicable (often recommended for Subarus of this era)


• Water pump, thermostat, and coolant service


• Oil changes and coolant flush as part of the procedure


• Head resurfacing or machining if the head is warped or damaged


• New gaskets for nearby components (intake/exhaust plenum, valve covers, etc.)

Costs can rise if the head is warped or cracked and requires machining, if additional leaks are detected, or if more extensive engine work becomes necessary. Always ask for a clearly itemized quote that lists parts, labor, and any machining or additional repairs.

Cost ranges and what affects the price

Prices depend on several factors, including where you are, which shop you choose, and what’s included in the service package. The following list outlines the main drivers of cost.

• Labor hours and shop hourly rate — Typical labor time for a Forester head gasket job is substantial, often in the 12–20 hour range, with hourly rates that can vary widely by region and shop (roughly $75–$150 per hour or more).


• Parts and materials included — A complete gasket kit, new head bolts, water pump, thermostat, coolant, and seals add to the price (roughly a few hundred dollars for basic components, more if premium parts are used).


• Machining or resurfacing — If the cylinder head is warped or damaged, resurfacing or even valve work may be required, which can add a few hundred to over a thousand dollars.


• Engine removal and access — In some cases, the engine or subcomponents may need to be removed to access the head, increasing labor time and cost.


• Regional labor rates — Prices tend to be higher in urban or high-cost areas and lower at independent shops in less expensive regions.


• Dealer vs. independent shop — Dealers generally charge more, while independent shops may offer more competitive pricing with varying levels of warranty.


• Additional repairs discovered during the job — If other issues (like a warped head, valve seal failure, or timing components) are found, the total cost can rise.

In summary, you’re looking at a wide range: approximately $1,500 on the low end with careful pricing and minimal machining, up to $3,500 or more in many markets, and potentially higher if substantial machining or engine work is required.

What to watch for and how to get an accurate quote

To avoid surprises, get a detailed, written estimate that breaks down labor hours, parts, and any potential machining. It’s also wise to obtain multiple quotes from reputable shops and ask about warranties on parts and workmanship.

Tips for obtaining a precise estimate

• Ask for an itemized quote that lists parts, labor, and any machining or coolant/service fees.


• Request a separate line item for possible head resurfacing or valve work if required.


• Inquire whether the price includes timing components and a water pump, or if those are optional add-ons.


• Check labor times against the shop’s published hours or a BOM (bill of materials) to ensure comparable estimates.


• Ask about the warranty on parts and labor and what it covers (typically 12 months/12,000 miles or more).

Being proactive about what’s included can help you avoid sticker shock and ensure you’re comparing like-for-like quotes.

Summary

Replacing a head gasket on a 2010 Subaru Forester is a major repair with a wide price range. In many markets, expect roughly $1,500 to $3,500, though higher quotes are common if machining, engine removal, or additional parts are required. The final cost depends on labor rates, regional differences, the condition of the head, and whether comprehensive parts and services are included in the job. By obtaining detailed, itemized quotes and clarifying what’s included, you can make a well-informed decision about repairing or considering alternative options for your Forester.

Can you change a Subaru head gasket without removing the engine?

So, can you replace a head gasket without removing the engine? The answer to this question is a resounding yes. While in-vehicle head gasket replacement is a viable alternative for some vehicles and specific head gasket issues, it's not a one-size-fits-all solution.

Is it worth fixing a blown head gasket?

Whether a blown head gasket is worth fixing depends on the car's value and the extent of the damage. It's likely worth repairing if the vehicle is in good overall condition and the repair cost is significantly less than the car's market value. However, it may not be worth the cost if the repair will exceed the car's value or if the engine has sustained severe damage, potentially making a new-to-you car a better investment.

When to fix a blown head gasket

• Your car is in good condition and valuable: If the vehicle has low mileage, is reliable, and you plan to keep it for a long time, the cost of a head gasket replacement can be justified. 
• The repair cost is significantly less than the car's value: A common rule of thumb is that the repair cost should be less than half the vehicle's worth. 
• The damage is limited: The head gasket failure hasn't caused other major engine issues like a warped or cracked block. 

When it may not be worth fixing

• The repair cost is close to or exceeds the car's value: If the repair is expensive and the vehicle is older or has high mileage, you might be better off selling the car for parts or buying a different one. 
• There is severe engine damage: A blown head gasket can sometimes lead to more serious problems like a damaged engine block or head, which can make the repair too expensive and not worth the cost. 
• The vehicle has other major issues: If the car has multiple significant problems, a head gasket repair may not be a wise investment. 

Other options to consider

• DIY sealers: For less valuable vehicles, a DIY head gasket sealer can be a temporary or potentially permanent low-cost solution to buy some time or prevent further damage, but a proper repair may still be needed later. 
• Replacing the engine: In some cases, it may be more cost-effective to replace the entire engine rather than just the head gasket, especially if the head itself is damaged.
