The radiator cap on a 2003 Saturn Vue is located on the engine's cooling system, typically at the front of the vehicle near the radiator. It is usually found on the top of the radiator or on the coolant reservoir, which is a white plastic tank connected to the radiator. Ensure the engine is cool before attempting to remove the cap to avoid injury from hot coolant.
On a 2001 Saturn L-Series, the radiator cap is located on the top of the radiator itself. It is typically a circular cap that can be unscrewed for coolant access. Ensure the engine is cool before attempting to remove it to avoid injury from hot coolant or steam.
