A container that holds engine coolant.
- Part of your engine's cooling system
- Stores and regulates excess coolant

The Engine Coolant Reservoir is a crucial component of the cooling system in your vehicle. Coolant helps your engine remain cool by absorbing the heat produced during combustion. Coolant runs on a cycle, which is where the Engine Coolant Reservoir comes in. When your engine heats up, the coolant expands, and excess coolant is pushed into the Engine Coolant Reservoir. As the engine loses heat, this coolant goes back to the radiator. The Engine Coolant Reservoir is also where new coolant is added before it flows to the radiator.
The Engine Coolant Reservoir is usually made of plastic, which makes it susceptible to cracking as time goes on. There are a few signs of an Engine Coolant Reservoir issue to keep an eye out for. If you need to add new coolant often, there could be a small leak or crack. You may notice puddles of greasy pink, yellow, or green fluid underneath the front of your vehicle. This is a sign of a coolant leak. When not caught in enough time, a damaged Engine Coolant Reservoir could also cause your engine to overheat.
Your owner's manual will tell you where your INFINITI Engine Coolant Reservoir is located and how to check your coolant level. Coolant gets extremely hot and can be a burn risk. Be sure to let your engine and radiator cool completely before you unscrew the reservoir cap. If your Engine Coolant Reservoir is leaking or cracked, you will want to replace it right away to help prevent engine damage. The coolant system can be dangerous to work with, so it's recommended you leave the installation to professionals.
Your INFINITI Engine Coolant Reservoir is a simple but important part of your engine's cooling system. When it's time to replace your Engine Coolant Reservoir, you need a reservoir made for your make and model. Shop genuine OEM parts to find the right fit.
