About the 4.7 Dodge Engine

Looking for a used 4.7 Dodge engine to power up your Ram 1500, Dakota, Durango, or Jeep Grand Cherokee? Whether you're restoring a high-mileage truck, completing a Jeep WJ or WK rebuild, or replacing a failed engine, this Used 4.7 Dodge engine for sale here offers a blend of power and dependable V8 character that Chrysler enthusiasts appreciate. Known as the Chrysler PowerTech 4.7L V8 (commonly searched as the "4.7 Magnum" although technically that name belongs to a different engine family), this engine was Chrysler's modern SOHC V8 successor to the older pushrod Magnum 5.2L. Whether you're tackling tough terrain in a Jeep or cruising on the highway in a Ram 1500, this 4.7 Dodge engine for sale on our site is the correct factory powerplant for a wide range of Dodge, Jeep, and Chrysler applications from 1999 through 2013.

Engine Overview: 4.7L PowerTech (Commonly Searched as "4.7 Dodge" or "4.7 Magnum")

This used 4.7L PowerTech V8 for sale on our site is a versatile naturally-aspirated 90-degree V8 known for its balance of performance and broad application range across the Chrysler / Dodge / Jeep lineup. It features a V8 configuration with displacement of 4.7 liters (287 cubic inches), offering reasonable horsepower and torque for trucks, SUVs, and crossover applications. The engine incorporates Sequential Multi-Port Fuel Injection for efficient fuel delivery and (in 2008 plus variants) Variable Valve Timing (VVT) for enhanced performance across different driving conditions. The PowerTech was Chrysler's first SOHC V8 truck engine, a significant architectural change from the OHV pushrod Magnum V8 family it replaced. Whether for towing, off-roading, or daily commuting, the 4.7 Dodge engine for sale here provides V8 power and the reliability of a proven Chrysler powerplant.

A Note on the "4.7 Magnum" Naming

Many buyers search for "4.7 Magnum engine" when looking for this powerplant. To be technically accurate: Chrysler's official Magnum V8 family consisted of the 5.2L Magnum and 5.9L Magnum engines only. The 4.7L V8 produced from 1999 through 2013 was officially named the PowerTech, not the Magnum. However, because the 4.7 replaced the 5.2 Magnum in Dodge trucks and uses similar Chrysler V8 architecture conventions, many buyers and even some parts suppliers refer to it informally as the "4.7 Magnum" or "Magnum III." If you searched for "4.7 Magnum engine for sale" and arrived here, this is the engine you're looking for. The proper technical name is the PowerTech 4.7L V8.

Features of the 4.7L PowerTech V8 Engine

• SOHC Valvetrain (Single Overhead Cam): This was Chrysler's first SOHC V8 in trucks and SUVs, providing better high-RPM breathing than the older OHV Magnum design while maintaining 2 valves per cylinder for simplicity and reliability.
• Sequential Multi-Port Fuel Injection (MPI): Ensures precise fuel delivery for optimal efficiency and power output.
• Variable Valve Timing (VVT, 2008 plus only): Adjusts intake valve timing for improved performance and fuel economy across the RPM range. Earlier 1999 to 2007 4.7L engines do NOT have VVT.
• Aluminum Cylinder Heads: Enhance durability and reduce weight versus older cast iron heads, contributing to better overall engine efficiency.
• Cast Iron Engine Block: Provides structural durability and proper cylinder bore stability for long engine life.
• Electronic Throttle Control: Provides smooth and responsive throttle response, enhancing drivability.
• Quiet Operation: Engineered for reduced noise levels versus the older pushrod Magnum V8, with the SOHC valvetrain naturally quieter than OHV pushrod operation.
• High-Strength Pistons and Connecting Rods: Powdered metal connecting rods for strength under high-stress conditions.
• Multi-Generational Application Range: Used across Dodge, Jeep, and Chrysler vehicles for 14 years (1999 to 2013), making parts availability strong.

• 2008 plus VVT-Equipped: 310 HP, 334 lb-ft (Ram 1500, Grand Cherokee WK, Commander, Aspen)

The HO and VVT variants are highly sought after for their meaningfully better power output. When ordering, specify which generation and variant matches your truck.

Engine Reliability and Durability

The 4.7 PowerTech is known for reasonable longevity when properly maintained, with examples reaching 200,000 to 300,000 miles when given proper care. However, the engine has documented weaknesses that buyers should understand:

Known Issues to Inspect for in a Used 4.7 PowerTech:

• Oil Sludge Buildup: The most documented 4.7L issue. The engine's tight oil passages and cam saddle design make it particularly susceptible to sludge buildup when service intervals are extended or non-synthetic oil is used. Sludge can starve cam bearings and lifters, leading to top-end failure. Mitigation: Use full synthetic oil with 5,000-mile change intervals.
• Valve Seat Erosion: The aluminum heads with pressed-in valve seats can develop seat erosion, especially in the exhaust valves. This causes loss of compression and rough running. Inspection: Compression test all 8 cylinders before purchase.
• Timing Chain Tensioner Failures: The hydraulic timing chain tensioners can fail at high mileage, leading to chain slap, broken guides, and (in worst cases) bent valves from chain skip. Inspection: Listen for chain rattle at cold startup.
• Cylinder Head Cracking: Less common but documented, particularly in HO variants subjected to detonation from low-octane fuel.
• Intake Manifold Plenum Gasket Failure: The intake plenum gasket can develop coolant leaks at high mileage, leading to overheating. Often confused with head gasket failure.

Maintenance Requirements

To keep your used 4.7 Dodge engine running smoothly, we recommend:

• Use full synthetic oil (5W-30 typically) with 5,000-mile change intervals to mitigate the sludge buildup risk
• Coolant system maintenance with proper Mopar HOAT coolant
• Addressing any leaks promptly to prevent overheating
• Use 87 octane regular gasoline for standard variants, 89 octane mid-grade for HO variants
• Replace spark plugs at recommended intervals (typically 100,000 miles with platinum plugs)
• Inspect timing chain tensioners and guides during any front cover removal
