To find out how much fluid your 1980 Chevy needs, you should:
1. Consult your owner's manual: This is the best source of information. It will specify the correct amount.
2. Check the power steering fluid reservoir: Look for a mark on the reservoir that indicates the "full" line. Add fluid only up to that line. *Never overfill.*
3. Search online: Search for your specific vehicle's year, make, and model (1980 Chevy [Truck/Car model]) along with "power steering fluid capacity" to find information from forums or repair sites.
Adding too much power steering fluid can be as damaging as adding too little. Always refer to your owner's manual or a reliable resource specific to your vehicle's power steering system.
