The Engine Coolant Reservoir is a crucial part of your INFINITI's cooling system. Coolant helps keep your engine cool by absorbing the heat produced during combustion Coolant works on a cycle, which is why you need an Engine Coolant Reservoir. As your engine heats up, the coolant expands, and excess fluid flows into your Engine Coolant Reservoir. As your engine cools down, this coolant goes back to the radiator. The Engine Coolant Reservoir is also where you add new coolant before it makes its way to the radiator.
The Engine Coolant Reservoir is typically made of plastic, which makes it vulnerable to cracking as time passes. There are a few signs of an Engine Coolant Reservoir issue to be aware of. If you're constantly needing to add new coolant, there could be a crack or small leak. You may see puddles of greasy green, yellow, or pink liquid underneath the front of your vehicle. This is a sign of a coolant leak. When not caught quickly enough, a damaged Engine Coolant Reservoir could also lead to your engine overheating.
Your owner's manual will tell you where your INFINITI Engine Coolant Reservoir is located and how to check your coolant level. Coolant reaches extremely high temperatures and can be a burn risk. Remember to let your radiator and engine completely cool down before removing the reservoir cap. If you realize your Engine Coolant Reservoir is cracked or leaking, you will want to replace it immediately to help avoid engine damage. Coolant can be dangerous to work with, so it's advised you let professionals handle the replacement.
Your INFINITI Engine Coolant Reservoir is a basic but essential part of your cooling system. When it's time for a replacement, you need a reservoir made for your specific vehicle. Purchase genuine OEM parts to find the right fit.
