1998 Dodge Caravan — 2.4L L4

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 Caravan 2.4L L4.

Body VANEngine 2.4L L4Transmission Automatic 3-spd

The 1998 Dodge Caravan 2.4L L4 serves as an NS platform VAN equipped with a 2.4L L4 engine and Automatic 3-spd transmission that returns 18/24/20 mpg. While the engine requires 5 qt w/ filter of 5W-30 / 10W-30 API oil, the vehicle's historical record includes 14 recalls and 671 total owner complaints primarily focused on Engine & Engine Cooling. Within the 1990-2017 model complaint history, this model year registers substantially fewer issues than the 1996 peak of 1647 complaints while remaining far above the 2017 low of 1 complaint. This data places the 1998 Caravan in a moderate position within the lineage's reliability trajectory, distinguishing it from both the generation's most problematic and most dependable years.

From the factory this vehicle uses a BCI 34 · 600 CCA battery, OE oil filter 05281090AB. Note the factory engine air filter, fuel filter and thermostat are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 30,000 mi. The big-interval services (every 30,000 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 1998 Dodge Caravan sits in the descending phase of a generation that peaked sharply in 1996 at 1,647 complaints and 16 recalls, with elevated activity continuing through the late 1990s. Its 671 complaints, 14 recalls, and 7 investigations represent a clear drop from 1997's 787/15/7 and a steep retreat from 1996, while still sitting well above the early-decade lows of 333 complaints and 6 recalls in 1990. Recall volume remained in the mid-teens, indicating continued manufacturer attention to defects, and TSB counts stayed high at 120 (versus 137 in 1997 and 89 in 1996), suggesting the brand was actively documenting service issues even as consumer complaints receded. The top complaint clusters—Engine & Engine Cooling (111), Power Train (85), Air Bags (63), and Fuel System/Gasoline (34)—concentrate around powertrain and restraint concerns, with 48 crash-related and 27 fire-related complaints logged for the year, though the data does not specify root causes behind these categories. Taken together, 1998 is a transitional, middling year: the trend line is improving, but it still carries meaningful recall and powertrain burden, so a pre-purchase inspection focused on cooling system health, transmission behavior, and verification that all 14 recalls were completed is advisable before buying.
