Radiator Overflow Bottle Tank - Nissan Patrol Y60 GQ & Y61 GU

Radiator Overflow Bottle Tank - Nissan Patrol GQ GU

This radiator overflow bottle, also known as a coolant expansion tank, is located in the engine bay, typically mounted to the inner guard. It functions as a reservoir for coolant that expands from the radiator as the engine reaches operating temperature. As the engine cools, a vacuum is created, drawing the coolant back into the radiator, ensuring the system remains full and free of air.

Over time, the original plastic bottle is exposed to constant heat cycles, causing it to become brittle, yellowed, and prone to cracking. This can lead to coolant leaks and makes it impossible to accurately check the coolant level. Replacing a failing overflow bottle is crucial for maintaining the health of your vehicle's cooling system.

Failure to replace a cracked or leaking overflow bottle can result in a gradual or sudden loss of engine coolant. This can introduce air into the cooling system, leading to inefficient cooling and, ultimately, engine overheating. Severe overheating can cause catastrophic engine damage, such as a warped cylinder head or blown head gasket, resulting in costly repairs.
