For a 2015 Jeep Grand Cherokee, typical head gasket replacement costs fall in the low to mid $0s range when all factors are considered, with most drivers paying roughly $1,600 to $4,000 depending on the engine and extent of necessary work. The exact price depends on the engine variant (3.6L, 5.7L, or EcoDiesel), the shop’s labor rate, and any additional parts or repairs needed during the job.
What influences the price
The total cost to replace a head gasket is driven by several variables, including engine type, labor intensity, and the need for ancillary parts. The following factors commonly impact the final bill.
- Labor hours required: Head gasket work is one of the most labor-intensive repairs, often ranging from about 12 to 20 hours depending on engine type and accessibility.
- Parts and materials: Gasket sets, seals, head bolts, coolant, oil, and possibly a timing kit, water pump, or thermostat add to the base price.
- Engine variant: Larger or more complex engines (like a V8 Hemi or EcoDiesel) generally cost more due to extra parts and longer labor times.
- Shop location and hourly rate: Regional differences in labor costs can widen or narrow the overall price.
- Preexisting damage and machining: If the cylinder heads require resurfacing or if there are warped heads, the price increases.
In practice, a diagnostic check is often worth doing to confirm head gasket failure and to rule out other cooling system issues, which can influence the final quote.
Cost estimates by engine
The following engine-specific ranges reflect typical labor rates and part costs in the United States. These figures include parts and labor but exclude tax, shop fees, and potential machining or core charges. Use them as a guide when obtaining quotes from mechanics.
3.6L Pentastar V6
The 3.6L V6 is the most common engine in the 2015 Grand Cherokee, with relatively straightforward access but still a labor-heavy job.
- Estimated total: $1,600 – $3,000
Notes: Costs can rise toward the upper end if heads require resurfacing, if cooling and timing components are replaced, or if diagnostic work uncovers additional issues. Typical repair time is around 12–16 hours.
5.7L Hemi V8
The 5.7L Hemi involves a larger engine with more components to address, which generally pushes the price higher than the 3.6L.
- Estimated total: $2,000 – $4,000
Notes: Expect higher labor hours (roughly 14–18 hours) and potential added costs for extra parts or machining if necessary. Quotes tend to cluster toward the middle or upper end of this range depending on the shop.
3.0L EcoDiesel
Diesel engines present additional considerations (torque requirements, more robust components), often making head gasket work more expensive.
- Estimated total: $2,500 – $4,500
Notes: EcoDiesel head gasket replacements frequently run toward the higher side due to diesel-specific components and potential for additional engine work. Expect longer diagnostic times and higher labor costs.
What to expect during the repair
When a shop performs a head gasket replacement, you should anticipate a multi-step process: diagnostic confirmation, removal of major components to access the cylinder heads, gasket replacement, possible head resurfacing, replacement of associated parts (water pump, timing components, thermostat, seals), and a coolant/oil flush. After the repair, the engine is pressure-tested and reassembled, followed by a careful startup and leak-check to ensure a proper seal.
Summary
Replacing a head gasket on a 2015 Jeep Grand Cherokee is a major mechanical job with cost largely tied to engine type and labor rates. For most owners, expect roughly $1,600–$3,000 for the 3.6L, $2,000–$4,000 for the 5.7L, and $2,500–$4,500 for the EcoDiesel, with variations based on machining needs and extra component replacements. Always obtain multiple quotes and confirm what is included in the price (parts, labor, fluids, and any return-to-operating tests) before proceeding.
What is the lawsuit on the 2015 Jeep Grand Cherokee?
FCA, alleges the manufacturer sold their 2014-2015 Jeep Cherokee, 2015 Chrysler 200 and 2015 Jeep Renegade vehicles knowing they contained defective ZF 9HP automatic transmissions. Plaintiffs allege the transmissions jumped, lurched, shook, or caused rough shifting or loud noises while shifting.

Is it worth fixing a blown head gasket?
If you don't repair a blown head gasket, your engine can incur significant damage, starting with loss of engine power and ultimately leading to complete engine failure.
Can I drive my Jeep with a blown head gasket?
FAQs: Jeep Head Gasket Issues
Technically, yes — but it's not a good idea. Driving with a blown head gasket can quickly cause more severe damage, such as a cracked engine block or failed bearings due to coolant mixing with oil. It's best to have it inspected as soon as possible.
