However, the exact location can vary slightly depending on specific trim levels and options. It's best to:
1. Consult your owner's manual: This is the most reliable source for the precise location.
2. Look for a reservoir with a dipstick or markings: Many power steering reservoirs have a dipstick to check fluid level or markings indicating the minimum and maximum fill lines.
3. Search online for pictures: A Google Image search for "1986 Dodge Ram Van 150 power steering reservoir" might show you pictures of the reservoir's location on similar vehicles.
Important Note: Be careful when adding power steering fluid. Overfilling can be just as bad as underfilling. Only add fluid up to the recommended level. If you're unsure, it's always best to consult a mechanic.
