Replacing the engine in a 2012 Nissan Altima typically costs about $2,000–$6,000 if you install a used or remanufactured engine, and $4,000–$8,000+ for a brand-new OEM engine installed. The total price depends on which engine you choose (2.5L four-cylinder vs. 3.5L V6), plus labor and regional rates.
In the 2012 Altima, Nissan offered two main engine options: a 2.5-liter four-cylinder (QR25DE) and a 3.5-liter V6 (VQ35DE). Replacement costs vary by whether you source a used engine, a remanufactured long block, or a new OEM long block, and by labor charges and any ancillary parts required. The sections below break down typical price ranges and the factors that influence the final bill.

Cost of installation and total price
Turnkey installed costs include labor, mounting hardware, seals, gaskets, and any required ancillary parts. The following ranges represent typical installed prices for complete replacements by engine type.
- 2.5L installed turnkey price: Used engine: about $3,000–$5,500; Remanufactured: about $4,000–$7,000; New OEM: about $6,000–$9,000.

Prices vary by region, shop, and whether the job requires additional services (timing components, water pump, sensors, exhaust work, or wiring upgrades). Always request a detailed, itemized quote.
Where to source an engine and how to compare quotes
Common sources include dealer-supplied new OEM engines, remanufactured long blocks from aftermarket suppliers, and used engines from salvage yards. Each option has tradeoffs in price, warranty, and reliability.
- New OEM long block from Nissan/Dealer: typically the most expensive but may offer longer warranty; approximate ranges: 2.5L $3,000–$4,500 before installation; 3.5L $4,000–$6,500 before installation.
- Remanufactured long block from aftermarket suppliers: commonly $2,000–$3,800 (2.5L) or $3,000–$5,000 (3.5L) before installation.
- Used engine from salvage yards: usually $1,200–$2,800 (2.5L) or $2,000–$4,000 (3.5L) before installation; warranties vary by seller.
Important considerations include confirming compatibility with your vehicle’s VIN, ensuring proper ECU handling or reprogramming if needed, and understanding what is included in the warranty and what is not.
Warranty considerations and what to watch for
Engine warranties vary by source. New OEM units often come with longer coverage (often 12–36 months or a mileage limit), while remanufactured and used engines may include shorter or more limited warranties. Always verify what the warranty covers (parts vs. labor), the duration, and any exclusions, and request documentation of any tests performed before installation.
Summary
For a 2012 Nissan Altima, overall engine-replacement costs range broadly based on engine choice and installation specifics. A typical installed price is roughly $3,000–$9,000+, with lower numbers for a used or remanufactured 2.5L engine and higher figures for a new OEM 3.5L installation. To get an accurate quote, obtain multiple detailed estimates that specify engine type, included components, labor hours, and warranty terms. Weigh the cost against the car’s overall condition and remaining expected lifespan to make the best financial decision.
