Where to find the exact capacity for your truck
To locate the precise refrigerant capacity for your specific vehicle, use these sources.
- Look for the A/C service label under the hood near the radiator or on the compressor housing, which often lists the refrigerant type (R-134a) and total charge.
- Consult the owner's manual or a factory service manual for your exact engine/transmission combination.
- Ask a dealership or a licensed automotive HVAC technician who can verify the charge for your VIN and model year.
Using the correct total charge is important to ensure proper cooling performance and to avoid compressor damage. If you suspect a leak or improper charge, have the system tested with the appropriate gauges and recovery equipment before recharging.
