2003 Dodge Caravan — 3.3L V6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2003 Caravan 3.3L V6. Covers both the standard and High Output 3.3L V6.

Body VANEngine 3.3L V6Transmission Automatic 4-spd

The 2003 Dodge Caravan is a front-wheel-drive van built on the RS platform, equipped with a 3.3L V6 engine and a 4-speed automatic transmission. It delivers an EPA-estimated 17 mpg city and 24 mpg highway, and its 5-quart oil capacity with 5W-30 API oil underscores straightforward maintenance. Within the model’s complaint history spanning 1990 to 2017, this year’s 195 owner complaints—predominantly about steering—mark a sharp decline from the 1996 peak of 1,647, though nine recalls signal that some reliability concerns persist.

From the factory this vehicle uses a BCI 34 · 500 CCA battery, OE oil filter 04105409AE. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 100,000 mi; coolant every 100,000 mi. The big-interval services (every 100,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2003 Dodge Caravan sits near the tail end of a steady improvement arc for this generation. Complaint volumes declined from a peak of 1,647 in 1996 through 260 in 2001, 256 in 2002, and dropped to 195 in 2003—the lowest level since the early 1990s. Investigations fell sharply to just 1 in 2003 (down from 5 the prior year), and TSBs dropped to 70 from 101, suggesting the manufacturer was resolving known issues. Compared to 2004's even lower 64 complaints and 8 recalls, 2003 represents a transitional year where the worst of the generation's problems had largely been addressed but not yet fully stabilized. The top complaint categories—Steering (33), Service Brakes/Hydraulic (24), Electrical System (15), and Power Train (13)—indicate persistent structural concerns rather than isolated defects, though crash-related complaints (13) and fire complaints (5) remained relatively contained. **This is a reasonably good year to buy within this generation:** the worst of the defect history has passed, recall activity is moderating, and the vehicle benefits from the lessons learned during the 1996–2003 refinement period, while remaining older than the markedly cleaner 2004–2007 model years.
