To find it:
1. Consult your owner's manual: This is the best source for the precise location and type of power steering fluid your van requires.
2. Look around the engine: It's often near the power steering pump itself, usually towards the front of the engine compartment. Look for a reservoir with a cap that might be labeled "Power Steering Fluid" or have a steering wheel symbol.
3. Check online: A quick search for "[Your Year] Dodge Ram 2500 Power Steering Fluid Reservoir Location" with images will likely show you pictures of where it is on your specific model.
Important Note: Never overfill the power steering fluid reservoir. Adding too much can cause problems. Fill it to the "maximum" line indicated on the reservoir.
