To find out the exact amount, you need to:
1. Check your owner's manual: This is the best source of information. The manual should specify the refrigerant capacity for your specific truck's air conditioning system.
2. Look for a sticker under the hood: Many vehicles have a sticker somewhere under the hood that lists specifications, including the AC refrigerant capacity.
3. Consult a repair manual: A Haynes or Chilton repair manual for your specific year and model Silverado will likely list the refrigerant capacity.
4. Ask a mechanic: An auto mechanic familiar with your vehicle can tell you the correct amount. They will have access to resources to find the correct specification.
Attempting to add refrigerant without knowing the correct amount can damage your AC system. It's best to get this information accurately before attempting any AC work.
