The Dodge 4.7 is Chrysler’s 4.7-liter (287 cubic inch) single-overhead-cam V8, introduced for the 1999 model year and used in the Jeep Grand Cherokee, Dodge Dakota and Durango, Ram 1500 and related vehicles until it was phased out in the early 2010s. It has an aluminum cylinder head design on an iron block, and a reputation that depends heavily on how well it was maintained.

Common Dodge 4.7 engine problems
- Oil sludge on engines with long oil change intervals, which starves the timing components and valvetrain of oil; see low oil pressure.
- Overheating damage, including dropped valve seats after the engine has run hot; keep the cooling system healthy and see engine overheating.
- Timing chain guide and tensioner wear, causing rattle at start-up and cam correlation codes; see timing chain symptoms and P0016.
- Head gasket leaks after overheating; see signs of a blown head gasket.
- Misfires from coils and plugs on high-mileage engines; see engine misfire.
How to keep a 4.7 healthy
- Change the oil on time with the specified grade; sludge is the root of many 4.7 failures.
- Fix cooling problems immediately and never keep driving an overheating engine.
- Listen for start-up rattle that points to timing chain wear.
Is the Dodge 4.7 a good engine?
Well-maintained 4.7s often run to high mileage, while neglected ones are known for sludge and heat-related failures. When buying a used vehicle with this engine, service records and a clean, sludge-free oil fill area are good signs.
