Where is the water filler port for the Buick Excelle's radiator located?

The water filler port for the Buick Excelle's radiator is located on the auxiliary reservoir. Simply open the radiator cap to add antifreeze. The radiator is marked with a warning not to open the cap when the engine is hot. Do not add ordinary water (tap water or mineral water) to the car's radiator. Instead, use automotive engine coolant (which does not freeze at low temperatures of 0°C and does not boil at high temperatures of 100°C). Coolant prevents scale buildup, ensuring the cleanliness of the engine's cooling system. Precautions for using the car's radiator are as follows: 1. Do not overfill the radiator: If adding water and filling it too much or completely, thermal expansion can cause significant overflow, leaving water stains and scale deposits. Additionally, water can create scale in the cooling system, clogging pipes, reducing cooling efficiency, and damaging the engine. The optimal operating temperature range for most car engines is 75-90°C; temperatures outside this range can negatively affect engine performance. 2. The coolant level should be maintained between the min and max marks: If it falls below min, add the same brand and specification of coolant or replace it entirely. Coolant selection is primarily based on the local minimum temperature, and factory-installed coolant is typically all-season. If the radiator does not leak, it may not require refilling for an entire year, but regular checks are still necessary.
The water tank filler cap of the Buick Excelle is usually located in the engine compartment, specifically on the right front side near the radiator and front crash beam. To be more precise, after opening the hood, you'll find a translucent plastic tank in the left front or right corner of the engine. The cap often has scale markings labeled 'Coolant' or 'coolant'. When adding water, always wait until the engine has completely cooled down before opening the cap, as hot engine steam can easily burn your hand—experienced drivers know this well. Use purified water or dedicated coolant for refilling, and avoid adding tap water. As a frequent Excelle driver, I find the design quite reasonable—the position is neither too high nor too low, making it easy to reach with a slight bend. If you can't locate it precisely, the manual's diagram is the most accurate. Maintaining the water tank properly can prevent engine overheating, especially before long trips—checking beforehand avoids breakdowns on the road. After all, just like people, cars stay healthy when they drink enough water.
