However, I cannot give you the precise location without a diagram specific to your vehicle's year and model. The location can vary slightly depending on the exact configuration of the engine bay.
To find it:
1. Consult your owner's manual: This is the best resource. It should show a diagram of the A/C system components, including the charging port.
2. Search online: Look for a "1995 Oldsmobile Achieva A/C system diagram" or a similar search term. Many repair manuals and websites show detailed diagrams.
3. Look carefully under the hood: The low-pressure port is usually on a relatively accessible part of the A/C lines, often near the compressor or condenser. Look for a capped valve that appears different from other fittings. Be cautious when working around the engine and A/C system, as there are high-pressure components.
Important Warning: Adding refrigerant is not a simple task. Improperly adding refrigerant can damage your A/C system. Low refrigerant is often a symptom of a leak, which needs to be repaired before adding more refrigerant. It's best to have a qualified mechanic diagnose and repair any A/C issues. They have the proper equipment to test the system, find leaks, and charge it correctly. Attempting to recharge the system yourself could void any warranty and possibly cause further damage.
