What Do I Put in the Coolant Reservoir?
The coolant reservoir is a crucial component of your vehicle’s cooling system. It holds the engine coolant, which is a mixture of water and antifreeze. The coolant reservoir is responsible for maintaining the correct level of coolant in the system, ensuring that the engine stays at a safe temperature. However, many car owners are unsure about what to put in the coolant reservoir. In this section, we will discuss the types of coolants, their benefits, and how to choose the right one for your vehicle.
Types of Coolants
Coolants come in different types, each with its own set of characteristics and benefits. The most common types of coolants are:
- Oxygen-ethylene glycol (OEG) coolant: This is the most common type of coolant used in vehicles. It is a mixture of water and ethylene glycol, which provides excellent freeze protection and corrosion inhibition.
- Propylene glycol (PG) coolant: This type of coolant is biodegradable and non-toxic. It is also more environmentally friendly than OEG coolants.
- Organic acid technology (OAT) coolant: This type of coolant is designed to provide long-term corrosion protection. It is also more environmentally friendly than OEG coolants.
- Hybrid organic acid technology (HOAT) coolant: This type of coolant combines the benefits of OAT and OEG coolants. It provides excellent corrosion protection and freeze protection.
- Dry coolant: This type of coolant does not contain any liquid. Instead, it uses a solid material to absorb heat from the engine.
When choosing a coolant, it’s essential to consider the following factors:
- Engine type: Different engines require different types of coolants. For example, some engines may require a specific type of coolant to prevent corrosion.
- Climate: If you live in an area with extremely cold temperatures, you may need a coolant with higher freeze protection.
- Environmental concerns: If you’re concerned about the environmental impact of your coolant, you may want to consider a biodegradable or non-toxic coolant.
Choosing the Right Coolant for Your Vehicle
Choosing the right coolant for your vehicle can be overwhelming, especially with so many options available. Here are some tips to help you make the right choice:

Frequently Asked Questions
What is the Coolant Reservoir and Why is it Important?
The coolant reservoir, also known as the expansion tank, is a crucial component of a vehicle’s cooling system. Its primary function is to hold excess coolant that expands when it heats up, preventing it from overflowing and causing damage to the engine. The coolant reservoir plays a vital role in maintaining the engine’s temperature, preventing overheating, and ensuring optimal performance. Regular checks and maintenance of the coolant reservoir are essential to prevent engine damage and ensure the longevity of the vehicle.
What Type of Coolant Should I Put in My Coolant Reservoir?
The type of coolant to use in the reservoir depends on the vehicle’s make and model. Most modern vehicles require a 50/50 mix of a specific type of coolant and distilled water. However, some vehicles may require a 100% coolant solution or a specialized coolant that meets the manufacturer’s specifications. It’s essential to consult the owner’s manual or speak with a mechanic to determine the correct type of coolant for your vehicle. Using the wrong type of coolant can lead to engine damage, reduced performance, and increased fuel consumption.
How Often Should I Check and Refill My Coolant Reservoir?
The frequency of checking and refilling the coolant reservoir depends on various factors, including driving conditions, climate, and vehicle usage. As a general rule, it’s recommended to check the coolant level every 3,000 to 5,000 miles or every 6 months, whichever comes first. Additionally, if you notice any signs of coolant leakage, overheating, or engine performance issues, it’s essential to check and refill the reservoir immediately. Regular maintenance can help prevent engine damage and ensure optimal performance.
What Happens if I Put the Wrong Type of Coolant in My Reservoir?
Using the wrong type of coolant in the reservoir can lead to serious engine damage, reduced performance, and increased fuel consumption.
