The coolant-only tank is a reservoir that holds the engine coolant. It is usually located under the hood of the vehicle, near the engine. The coolant-only tank is used to fill the engine with coolant when the coolant level is low.
Here are some things that go in engine coolant only tank:
* Engine coolant: Engine coolant is the main component of the coolant-only tank. It is a mixture of water and antifreeze, and it helps to prevent the engine from overheating.
* Antifreeze: Antifreeze is a chemical that is added to engine coolant to lower its freezing point. This is important in cold climates, where the coolant could freeze and damage the engine.
* Rust inhibitor: Rust inhibitor is a chemical that is added to engine coolant to help prevent the engine from rusting.
* Water pump lubricant: Water pump lubricant is a chemical that is added to engine coolant to help lubricate the water pump.
It is important to note that the coolant-only tank should never be filled with plain water. Water can freeze in cold climates and damage the engine, and it can also cause the engine to overheat in hot climates. Always use a mixture of engine coolant and water when filling the coolant-only tank.
