How the Estimate Is Built

1. Engine Source

• Used: Cheapest, but verify miles, compression, and VIN.
• Remanufactured: Reliable midrange option (~$3.3k–$5k for gas engines).
• Mopar crate/reman: Premium option ($6k–$8k), usually strongest warranty.

2. Labor Hours × Local Rate

• Typical book time: 16–24 hours depending on model year and AWD.
• Labor rate: $110–$176/hr (national average ~$143/hr).

3. Add-Ons Most Quotes Miss

• Fluids, filters, gaskets, belts, mounts, and hardware: $300–$1,200
• Cooling-system parts or sensors if overheated
• Core charges, shipping, shop fees, and taxes

Real Price Snapshots (for Comparison)

• Reman 3.6L Pentastar: $3,349 (advertised)
• Auto parts retailers: Mid-$4,000s for certain years

How to Get a Solid Quote

1. Ask for itemized estimates showing engine source, warranty, labor hours/rate, and inclusions.
2. Verify warranty terms: duration, what’s covered (parts-only vs. parts + labor).
3. Confirm add-ons: water pump, plugs, belts, mounts, fluids, gaskets.
4. Request details on core charges, taxes, and shop fees.
5. Compare the shop’s labor rate with local averages ($110–$176/hr).

Warranty & Risk Tips

• Reman engines often carry multi-year, parts-and-labor warranties. Ask for coverage length.
• Used engines are cheaper but usually come with 90–180-day warranties. Request compression/leak-down proof.
• EcoDiesel owners: verify any active emissions or recall-related coverage by VIN.

Bottom Line

• 3.6L Pentastar: Expect $6k–$12k installed
• 5.7L HEMI: Expect $6.5k–$11k installed
• 6.4L SRT: Expect $9k–$14k+ installed
• 3.0L EcoDiesel: Expect $13k–$18k+ (independent) / $20k–$26k (dealer)

If your quotes fall far outside these ranges, double-check the engine source, labor hours, and included parts which is where the differences usually hide.
