Preparation is Key: Understanding Your Infiniti Q50’s Cooling System
Before diving into the process of putting coolant in your Infiniti Q50, it’s essential to understand the basics of the cooling system. This knowledge will help you identify potential issues and ensure you’re using the right materials.
The Importance of Coolant
Coolant plays a vital role in maintaining your engine’s optimal operating temperature. It absorbs and dissipates heat from the engine block, cylinder head, and other components, preventing overheating and damage. The coolant also helps to protect the engine from corrosion by neutralizing acidic substances that can form in the cooling system.

Coolant Types and Mixtures
There are several types of coolants available, each with its unique properties and advantages. Some common types include:
- Organic Acid Technology (OAT) coolants: These coolants are designed for use in modern engines and are known for their ability to prevent corrosion and maintain engine performance.
- Inorganic Acid Technology (IAT) coolants: These coolants are more commonly used in older engines and are known for their ability to withstand high temperatures.
- Silicate-based coolants: These coolants are less common and are typically used in high-performance engines.
When selecting a coolant for your Infiniti Q50, it’s essential to choose a type that meets the manufacturer’s specifications. Mixing different types of coolants can lead to corrosion and other issues, so it’s best to stick with a single type.
Identifying the Coolant Capacity of Your Infiniti Q50
To determine the correct amount of coolant to add, you’ll need to consult your owner’s manual or the manufacturer’s specifications. The coolant capacity will vary depending on the engine type and model year. Some common coolant capacities for the Infiniti Q50 include:
- 3.7L V6 engine: 5.5 quarts (5.2 liters)
- 3.0L V6 Hybrid engine: 5.5 quarts (5.2 liters)
- 3.0L V6 Diesel engine: 6.5 quarts (6.1 liters)
It’s also essential to note that the coolant capacity may vary depending on the climate and driving conditions. In extreme temperatures, you may need to add more coolant to maintain the optimal operating temperature.
Tools and Materials Needed
Before starting the process, make sure you have the following tools and materials:
- Coolant: Choose a type that meets the manufacturer’s specifications.
- Coolant reservoir cap: Make sure it’s securely tightened to prevent leaks.

Locating the Coolant Reservoir and Radiator in the Infiniti Q50
The first step in adding coolant to your Infiniti Q50 is to locate the coolant reservoir and radiator. This is crucial to ensure that you fill the correct compartment with the right amount of coolant. The location of these components may vary depending on the model year of your vehicle.
Coolant Reservoir Location
The coolant reservoir is a transparent plastic container that holds the engine coolant. It is typically located on the driver’s side of the engine compartment, near the radiator. The reservoir has a cap on top, which you will need to remove to check the coolant level and add new coolant if necessary.
Here’s a step-by-step guide to locate the coolant reservoir in your Infiniti Q50:
- Open the hood of your vehicle and look for the driver’s side of the engine compartment.
- Locate the radiator, which is a large, rectangular component with hoses connected to it.
- Behind the radiator, you should see a transparent plastic container with a cap on top. This is the coolant reservoir.
- Check the cap for any labels or markings that indicate the type of coolant recommended by the manufacturer.
Radiator Location
The radiator is a critical component of your vehicle’s cooling system, and it’s essential to locate it before adding coolant. The radiator is typically located in the front of the engine compartment, and it’s a large, rectangular component with hoses connected to it.
Here’s a step-by-step guide to locate the radiator in your Infiniti Q50:
