Prices vary by engine type and condition; for the 2014 Terrain, the two engine options are a 2.4-liter Ecotec four-cylinder or a 3.6-liter V6. Overall, you’re looking at a pre-labor price range roughly from about $1,000 to $8,000 depending on whether you buy a used, remanufactured, or new long block.
More detail: the Terrain’s 2014 lineup can be equipped with either a 2.4L Ecotec I4 or a 3.6L V6. Costs rise with the size and complexity of the engine, and with whether you source a new, remanufactured, or used unit. Labor, core charges, and related parts all shape the final installed price.
Engine options and typical price ranges
Below is a snapshot of typical price ranges you might see before labor, organized by engine type.
- 2.4L Ecotec I4 — New long-block: about $3,000–$4,800; Remanufactured: about $2,000–$3,800; Used: about $1,000–$2,500
- 3.6L V6 — New long-block: about $5,000–$7,500; Remanufactured: about $3,500–$6,000; Used: about $2,000–$4,000
Prices vary by supplier, shipping, core charges, and whether you buy a complete long block or a kit with ancillary parts. Always confirm with the vendor for exact numbers and warranties.
Installation and related costs
In addition to the engine itself, installation and related components can substantially affect the total. The following ranges cover common scenarios.
- Labor: roughly 6–15 hours at $75–$120 per hour, depending on shop location and complexity
- Core charge: typically $50–$200, often credited back when the old engine core is returned
- Additional parts and services: timing chain/belt kit, water pump, thermostat, seals, fluids, hoses, and diagnostic checks — roughly $300–$1,200
- Shipping and handling for the engine block or kit: about $100–$400
Some shops offer bundled pricing with warranties, which can affect the headline cost. It’s wise to request a written, itemized quote that includes the engine, labor, parts, and warranty terms.
What to consider when shopping for a used or rebuilt engine
Engine history matters: mileage, prior repairs, and service records influence reliability and future maintenance costs. Vendors vary in what they offer and how they warranty a used or remanufactured engine. Remanufactured units often carry longer warranties and may include upgraded components (e.g., timing chains, seals) compared with a simple used block.
Bottom-line guidance: for a 2014 Terrain, total installed costs typically range from roughly $4,000 on the low end (remanufactured 2.4L with labor) to $9,000 or more for a new 3.6L long block with installation, depending on components and regional labor rates.
Summary
The cost to replace a 2014 GMC Terrain engine depends largely on which engine you choose (2.4L vs 3.6L) and whether you select a used, remanufactured, or new long block. Labor and ancillary parts can significantly influence the final price. Prospective buyers should shop around, obtain multiple quotes, clarify warranties, and ensure quotes cover engine, labor, parts, and any core charges.
