To find out how much coolant your specific Buick Regal needs, you should:
* Check your owner's manual: This is the most reliable source of information. The manual will specify the exact capacity for your vehicle's cooling system.
* Look for a sticker: Sometimes, a sticker inside the radiator cap or under the hood will indicate the coolant capacity.
* Consult a repair manual: Repair manuals (like those from Haynes or Chilton) provide detailed specifications for various car models.
Do not simply fill the radiator to the top. Cooling systems are designed with an overflow tank, and filling only the radiator will not account for the coolant in the engine block and hoses. Always follow the instructions in your owner's manual to ensure you fill the system correctly. Incorrectly filling the cooling system can lead to overheating or other damage.
