Transmission Type Diesel:
Likely a 4-speed automatic transmission (e.g., 42LE or similar)
Transmission Type Gas Optional:
While the manual specifies diesel, gasoline variants often offered a 5-speed manual or 4-speed automatic. This manual specifically addresses diesel.
Transmission Control:
Electronic transmission control module (TCM)
Wheelbase:
Approx. 119.2 inches (Grand Caravan) / Approx. 111.8 inches (Caravan)
Length:
Approx. 195.5 inches (Grand Caravan) / Approx. 177.1 inches (Caravan)
Width:
Approx. 72.0 inches
Height:
Approx. 68.8 inches (Grand Caravan) / Approx. 67.4 inches (Caravan)
Curb Weight:
Varies by configuration, but likely higher for diesel models due to engine and transmission.
Cargo Volume:
Significant cargo capacity, especially in the C/V configuration and Grand Caravan variants.
Oil Change Interval:
Typically every 7,500 miles or 6 months, but consult manual for diesel-specific recommendations.
Diesel Fuel Filter Interval:
Recommend replacement at intervals specified by the manufacturer, usually around 30,000 miles, but critically important for diesel fuel system longevity.
Transmission Fluid Interval:
Inspect every 30,000 miles, change fluid and filter as per manual recommendations (often around 60,000-100,000 miles depending on driving conditions).
Engine Oil Spec:
Refer to manual for specific API/ACEA classification and viscosity grade for the 2.8L CRD diesel engine (e.g., SAE 5W-40 or 10W-40, meeting specific diesel oil standards).
Transmission Fluid Spec:
Refer to manual for specific ATF specification (e.g., ATF+4 or equivalent).
Coolant Spec:
Refer to manual for appropriate antifreeze/coolant type and mixture ratio (e.g., HOAT or OAT coolant).
Diesel Engine Reliability:
Common issues can include glow plug system failures, EGR valve issues, and potential fuel injector problems if not maintained properly. Turbocharger and related plumbing can also be points of attention.
Transmission Issues:
The automatic transmission can sometimes experience hard shifting or premature wear if fluid and filter maintenance is neglected.
Power Steering:
Leaking power steering pumps or hoses are a relatively common concern.
Electrical Gremlins:
As with many vehicles of this era, intermittent electrical issues with sensors, modules, or wiring can occur.
Dodge Heritage:
Dodge has a long history in the automotive market, known for performance and utility vehicles. The Caravan/Voyager/Town & Country platform pioneered the minivan segment.
Caravan Fourth Gen:
The 2003 model is part of the fourth generation (RS) of the Dodge Caravan and its Chrysler sibling, the Town & Country, which debuted for the 2001 model year and continued with minor updates through 2007.
