Where is the low side port for recharging AC on a 2001 Buick Century?

The low-side AC recharge port on a 2001 Buick Century is typically located on the front of the compressor. It's usually a smaller port, often with a blue cap. However, it's crucial to verify this visually. There's no guarantee it will *always* be in that exact location. Different years, even within the same model, can have slight variations.

Before attempting any AC recharge:

* Consult your owner's manual: It's the best source for specific information about your vehicle's AC system.

* Look for markings: The ports might have labels or color-coded caps (blue for low side, red for high side).

* Use caution: The high-side port is under significantly higher pressure and can be dangerous if accidentally accessed.

If you're unsure, it's best to take your vehicle to a qualified mechanic for AC service. Improperly charging your AC system can damage the compressor or other components.
