For a 2016 Honda Accord, head gasket replacement typically costs about 1,200 to 2,000 USD for the 2.4L four-cylinder model, and roughly 1,800 to 3,000 USD for the 3.5L V6, depending on engine condition, labor rates, and location.
The head gasket job is a major repair that involves removing the cylinder head, replacing the gasket, and often replacing related components such as the water pump, timing chain tensioners, and cooling system parts. Costs can climb if the head is warped or if additional engine damage is found.
What affects the price
Several factors influence the final quote. Engine variant, severity of damage, labor rates by region, included parts, and whether any additional repairs are required all drive the total.
Cost ranges by engine type
The following ranges reflect typical U.S. quotes from shops in 2024–2025 and include parts, labor, and common add-ons. Exact prices will vary by location and shop.
- 4-cylinder 2.4L engine: roughly 1,200 to 2,000 USD. Labor is typically about 8 to 12 hours at regional rates, and parts may include the head gasket set, oil, coolant, seals, and often a water pump if it’s due for replacement.
- V6 3.5L engine: roughly 1,800 to 3,000 USD. This version generally requires more labor, and costs may rise if head resurfacing, head bolts, or additional seals are needed.
Prices can be higher if there is damage such as a warped head or cylinder head repair, or if a near-term replacement of the cooling system or timing components is included in the job.
What’s typically included in the service
Before this list, note what’s commonly included or recommended as part of the head gasket replacement, though exact inclusions vary by shop.
- Head gasket set (including gaskets for the head, intake, exhaust, and valve covers)
- Head bolts or studs (new, if required)
- Water pump and thermostat (often replaced as part of the job)
- Coolant, engine oil, and oil filter
- Seals and timing chain guides/tensioners if needed
- Head resurfacing if the cylinder head is warped
- Labor to disassemble and reassemble the engine and test drive
- Basic diagnostic checks and leak tests
Concluding note: While many shops include these items, always confirm exactly what is included in your quote and whether a head straightening or resurfacing is needed.
Tips for getting a fair quote
Get multiple written estimates, verify shop credentials, ask about warranties (parts and labor), and clarify whether the price includes coolant, oil changes, and any necessary hoses or seals.
Signs of head gasket trouble
Common indicators that a head gasket may be failing include overheating without a clear external cause, milky or contaminated oil, coolant loss with no obvious leaks, white exhaust smoke, and compression loss. Address symptoms promptly to prevent further engine damage.
Summary
Replacing a head gasket on a 2016 Honda Accord is a major repair with cost that varies by engine type and damage. Expect roughly 1,200–2,000 USD for the 2.4L engine and 1,800–3,000 USD for the 3.5L V6 in typical U.S. shops, with higher prices possible if head work or additional components are needed. To secure the best value, obtain several detailed written estimates, understand exactly what the quote covers, and check for warranties on both parts and labor.
