Roughly $3,000 to $7,000 for a complete engine replacement, depending on engine source (used, rebuilt/remanufactured, or new OEM) and local labor rates.
Engine replacement options and typical costs
Prices vary by source and coverage. The following ranges cover common routes to replace the Ridgeline’s 3.5-liter V6 engine and give a sense of total costs, including parts and typical installation considerations. Note that labor is usually extra and can vary widely by region and shop.
- Used engine from a salvage yard: typically $1,000–$2,500 for the engine itself; expect additional costs for installation and any needed ancillary parts.
- Remanufactured (rebuilt) long-block: commonly $2,500–$4,500 for the engine; labor and any necessary peripherals add on top.
- New OEM crate engine: around $4,000–$6,000 (or more) for the engine alone; installation adds labor; availability can be limited for older vehicles.
- Aftermarket or non-OEM rebuilt option: roughly $2,000–$4,500 for the engine; labor varies by shop and may affect compatibility.
Labor is a major component of the total cost. On average, a typical engine swap can take 6–12 hours of shop time at rate levels of roughly $75–$150 per hour, translating to about $450–$1,800 in labor, depending on local rates and the exact job requirements.
What affects the price
Multiple factors influence the final bill. Here are the key drivers to consider when budgeting for an engine replacement:
- Engine source and type (used, remanufactured, new OEM, or aftermarket).
- Regional labor rates and shop overhead; urban areas and dealer service typically cost more.
- Supplementary parts and services included (timing chain/belt, water pump, seals, gaskets, hoses, coolant, oil, sensors, wiring).
- Warranty options and duration, including whether the engine includes a parts-and-labor warranty.
- Availability and lead times for the chosen engine, especially for older models where new units may be scarce.
- Vehicle condition and additional work required to complete the swap (transmission compatibility, ECU programming, exhaust work).
- Core charges for used engines and whether cores are returned in good condition.
To minimize surprises, request itemized quotes that separate parts, labor, fluids, disposal, and any core charges, and ask about what is included in the warranty coverage.
Getting an accurate quote
To obtain a precise price for your Ridgeline, contact several shops (including Honda dealers and independent mechanics) with your VIN, engine code, and a description of the problem. Ask for a written estimate that includes labor hours, parts, and any recommended ancillary work, and request warranty terms for both parts and labor.
Summary
For a 2006 Honda Ridgeline, a complete engine replacement typically falls in the $3,000–$7,000 range, with the lower end reflecting used or remanufactured options and the higher end representing new OEM crate engines. Labor, availability, and the need for additional parts can push the total higher. Prospective buyers should secure multiple quotes, verify what’s included, and consider long-term reliability and remaining resale value when deciding among used, rebuilt, or new engines.
