* Check your owner's manual: This is the most reliable source of information. The manual will specify the coolant capacity for your particular Cadillac model and engine.
* Look for a sticker under the hood: Many vehicles have a sticker under the hood near the radiator or coolant reservoir that lists vital fluid capacities, including coolant.
* Consult a reliable online resource: Websites like RepairPal or others specializing in automotive repair information may have specifications for your specific Cadillac model and engine. Be sure to enter the year, make, model, *and engine size* for the most accurate results.
Without knowing the engine size of your 2000 Cadillac, it's impossible to give you a definitive answer.
