* Engine type: Different generations of Caravan had different engines, some more reliable than others. The specific engine (e.g., 2.4L, 3.3L, 3.6L, etc.) significantly impacts longevity.
* Maintenance: Regular maintenance, including oil changes, coolant flushes, and other scheduled services, dramatically extends engine life. Neglect leads to premature wear.
* Driving habits: Aggressive driving, frequent short trips (which prevent the engine from reaching optimal operating temperature), and towing heavy loads all put extra stress on the engine, reducing its lifespan.
* Operating conditions: Extreme temperatures (very hot or very cold) can also affect engine longevity.
* Quality of parts used for repairs: Using inferior parts during repairs can lead to faster wear and tear.
While some Dodge Caravan engines might last over 200,000 miles with proper care, others might fail well before 100,000 miles due to neglect or inherent issues. Therefore, providing a single "average" number is misleading. You'll find widely varying anecdotal evidence online.
Instead of focusing on an average lifespan, it's more helpful to focus on proper maintenance to maximize the life of your Caravan's engine. Consult your owner's manual for the recommended maintenance schedule.
