Replacement engine costs for a 2010 GMC Terrain typically range from roughly $3,000 to $8,000 for installed work, depending on engine type, source (used, remanufactured, or new OEM), and labor rates.
The 2010 Terrain offered two engine options: a 2.4-liter four-cylinder and a 3.0-liter V6. Prices vary widely based on whether you buy a used engine, a remanufactured unit, or a brand-new OEM crate engine, as well as how much labor your shop charges and any additional components that must be replaced during the job.
Engine options for the 2010 Terrain
2.4-liter inline-four (Ecotec)
This engine was the standard option for many 2010 Terrain models. Replacement costs can vary significantly by source and configuration.
- Used 2.4L engine: $800–$1,800 (parts only)
- Remanufactured 2.4L engine: $2,500–$3,800 (parts only)
- New OEM crate 2.4L engine: $3,800–$5,000 (parts only)
Prices above reflect typical options for the 2.4L engine and do not include labor. Actual quotes will depend on the seller and regional pricing.
3.0-liter V6
The optional 3.0L V6 was offered on some Terrain configurations and generally carries higher replacement costs due to its size and parts requirements.
- Used 3.0L engine: $1,200–$2,600 (parts only)
- Remanufactured 3.0L engine: $3,200–$4,800 (parts only)
- New OEM crate 3.0L engine: $4,800–$6,000 (parts only)
As with the 2.4L, these figures exclude labor and any ancillary components you may need to replace during the swap.

Additional considerations and how to get an accurate quote
Before requesting quotes, gather as much information as possible to avoid surprises and to compare apples to apples.
- Vehicle identification number (VIN) and engine code to ensure compatibility.
- Current mileage and any accompanying issues (oil consumption, misfires, overheating).
- Preference for used, remanufactured, or new OEM engine, and any warranty expectations.
- Inclusions in the quote (timing kit, water pump, thermostat, seals, hoses, labor warranty).
To maximize your chances of getting a fair price, follow these steps:
- Request 3–5 quotes from independent shops, GM dealers, and reputable rebuilders.
- Ask what the warranty covers (engine, labor, and duration).
- Confirm whether the price includes any core charges, core return policies, and installation time estimates.
- Check current promotions or coupons that shops may offer on engine replacement work.
After reviewing quotes, compare not just price but also: warranty terms, included components, quoted timelines, and the shop’s reputation (reviews, certifications, and prior work on GM vehicles).
Summary
Replacing a 2010 GMC Terrain engine can range from roughly $3,000 to $8,000 installed, depending on engine type and sourcing (used, remanufactured, or new OEM) and labor. The 2.4L I4 is the more affordable option, while the 3.0L V6 generally costs more to replace. Always obtain multiple, detailed quotes and verify what is included in each price, including warranties and required ancillary parts. A careful comparison will help you choose the best balance of price, reliability, and long-term value.
