* Under the rear seat: This is the most common location for hydraulic pumps in classic cars. You'll likely need to remove or at least partially lift the rear seat cushions to check.
* Trunk area: Less common, but possible. Check along the inner trunk sides and under the trunk floor carpeting. Look for a cylindrical unit with hydraulic lines connected.
* Behind the inner rear wheel well: Sometimes the pump is tucked away in a less accessible location within the wheel well area. This would require removing some interior paneling.
How to find it:
1. Consult a 1965 Cadillac Eldorado shop manual: A factory service manual will provide the most accurate information regarding the location of specific components, including the convertible top pump. These are often available online or from classic car parts suppliers.
2. Trace the hydraulic lines: Follow the hydraulic lines that run to the convertible top mechanism. They'll lead directly to the pump.
3. Visual inspection: Systematically examine the areas mentioned above, looking for a relatively small, cylindrical unit with hoses and possibly electrical connections.
4. Online forums and communities: Search online Cadillac forums or communities dedicated to classic cars. Members often share experiences and photos regarding repairs and component locations.
Important Note: Before attempting any work on the convertible top system, disconnect the battery's negative terminal to prevent accidental shorts. Be aware that working with hydraulic systems can involve pressure and potential for leaks. If you're not comfortable with automotive repairs, it's best to consult a professional mechanic experienced with classic cars.
