* Coolant: The coolant reservoir is usually a translucent plastic container, often located near the front of the engine bay. It will likely be labeled "Coolant" or have a diagram showing a cooling system. Check your owner's manual for the exact location if you can't find it readily. Do not open the radiator cap directly to add coolant unless the engine is completely cold.
* Washer Fluid: The washer fluid reservoir is typically a larger container, often made of opaque plastic, and is usually located in the front of the engine compartment, often near the windshield wipers. It will be labeled "Washer Fluid."
Important Note: Always check your owner's manual for the specific locations and instructions for your vehicle. The manual will also advise on the type of coolant to use. Adding the wrong type of coolant can damage your engine.
