How do you put antifreeze in a rendezvous?

To add antifreeze to a Buick Rendezvous, first ensure the engine is cool and locate the coolant reservoir, which is typically a translucent plastic tank near the radiator. Open the cap and pour the antifreeze mixture, usually a 50/50 blend of antifreeze and distilled water, into the reservoir until it reaches the "full" line. Be careful not to overfill, and securely close the cap afterward. If necessary, check the radiator directly for coolant level by removing the radiator cap, but only do this when the engine is cold to avoid burns.
