Replacing the engine on a Buick Enclave can be quite costly, with prices typically ranging from $5,000 to $8,000 for parts and labor. However, the exact cost depends on a variety of factors.

What is Involved in Replacing an Enclave Engine?
A full engine replacement involves removing the old engine and installing a new or rebuilt engine in its place. This requires:
- Lifting the vehicle and removing the old engine
- Installing the new engine and connecting all hoses, sensors, belts, etc.
- Refilling fluids like oil, coolant, transmission fluid
- Reconnecting the exhaust
- Making sure the new engine runs properly
In addition to parts costs for the new engine, labor will be charged for the many hours it takes certified mechanics to complete this major repair. Most repairs shops estimate full engine replacements take 15-40 hours of labor.
Cost of Buick Enclave Engine Replacement Parts
The engine itself is the biggest expense for an Enclave engine replacement. Here are some typical costs for replacement engines:
| Engine Type | Cost |
| Used Enclave engine with 50k-100k miles | $2,000 – $4,000 |
| Rebuilt/remanufactured Enclave engine | $4,000 – $6,000 |
| New GM crate engine | $6,000 – $8,000 |
The Enclave uses a 3.6L V6 engine. Buick offered different versions over the years, but most replacements use a broadly compatible GM 3.6L V6. Used engines tend to cost less but come with no warranty – rebuilt and crate engines often have at least a 1-year warranty.
Other Replacement Parts and Costs
In addition to the engine itself, there are many related components that may need replacement during an engine swap:
- Starter – $200
- Alternator – $450
- Sensors – $50-$200 each
- Gaskets and seals – $150
- Engine mounts – $150
- Hoses and belts – $100
- Oil and filters – $75
- Coolant – $50
Many mechanics recommend replacing these parts proactively since you already have access during the engine removal. Assuming $500 or more for additional parts is a good estimate.
Labor Costs for Enclave Engine Replacement
The biggest cost beyond the engine itself will be labor. Book time for an Enclave engine replacement is 15-40 hours depending on exactly what needs to be done. At a shop rate of $100 per hour, you can expect to pay $1,500 – $4,000 for labor.
Getting an experienced mechanic familiar with Enclaves is advisable, even if the hourly rate is higher. This can reduce the total labor time and avoid mistakes that could lead to bigger problems down the road.
How to Save on Buick Enclave Engine Replacement
To save money on your Enclave engine replacement, consider these tips:
- Buy a used engine – can cut costs in half compared to new
- Negotiate on labor rates if paying out of pocket
- Provide your own parts to avoid markups
- Ask about warranties – even used engines often have short warranties
- Shop around for quotes – prices can vary widely between mechanics
- Consider having the head gaskets repaired first – may be much cheaper than full replacement
With some research and effort, it’s possible to save $1,000 or more compared to average replacement costs. But compromising on engine quality or mechanics skill is risky. Prioritize quality components and experienced mechanics for the best long-term value.
Conclusion
Expect to pay $5,000 to $8,000 or more for a complete Buick Enclave engine replacement with parts and labor. The engine itself will be $2,000 to $6,000 depending on whether you use a used, rebuilt or new engine. Add another $500+ for related parts replacements. And shop labor will cost $1,500 to $4,000 for 15-40 hours of work. With some smart negotiation and component choices, you can reduce costs. But focus on quality rather than cutting corners to ensure reliability.
