To determine the type of coolant your car needs, consult your owner’s manual. It typically specifies the recommended coolant type, whether it’s a conventional green ethylene glycol-based coolant, an extended-life coolant (usually orange or pink), or a specific type like Dex-Cool for GM vehicles. Another way to find out is by checking the coolant reservoir under the hood; it might have a label indicating the type of coolant required. It’s crucial to use the correct coolant to maintain optimal engine performance and prevent potential damage. If unsure, it’s best to consult a professional mechanic or refer to the manufacturer’s recommendations to avoid using an incompatible coolant that could harm your vehicle’s cooling system.
