Coolant recovery reservoir

Types of Coolant Recovery Reservoir

Automobile coolant reservoir tanks, also known as coolant expansion tanks, are an essential component of the engine cooling system. Their main purpose is to store and provide additional coolant to the engine when it needs it. Here are various types of coolant recovery tanks:

• Pressurized Coolant Tanks

Pressurized coolant recovery reservoirs are built to keep the cooling system under pressure. They are often connected to the radiator cap. The radiator cap has two valves. One of the valves opens and releases pressure to the coolant overflow tank when the pressure is too high. The other valve allows coolant to flow back into the radiator from the coolant reservoir. The radiator draws the coolant back when it cools down and creates a vacuum. The pressurized coolant tanks can be made from plastic or high-grade aluminum.

• Non-Pressurized Coolant Tanks

Non-pressurized coolant recovery tanks don't have a connection to the radiator cap. They are mostly situated beside the radiator or attached to the frame of the vehicle. The non-pressurized tanks are commonly made from plastic material. They are also more affordable than pressurized coolant tanks.

• Plastic Coolant Tanks

Plastic coolant tanks are generally found in older vehicle models. They are made from plastic polymer, which makes them affordable. However, these plastic coolant tanks are not durable, and they can get damaged by extreme temperatures. They are also not resistant to the corrosive actions of coolants.

• Metal Coolant Tanks

Metal coolant tanks are known for their durability and ability to withstand extreme temperatures. Aluminum is the most common metal used in making coolant tanks. These metal tanks are also resistant to the corrosive action of the coolant. They are, however, more expensive than plastic tanks.

• Threaded Coolant Tanks

Threaded coolant tanks are designed to be fitted with a screw-on radiator cap. This type of tank is commonly found in older vehicle models.

• Non-Threaded Coolant Tanks

Non-threaded coolant tanks do not have provisions for a radiator cap. They are mostly connected to the vehicle's cooling system using a hose barb.

Specification and maintenance of coolant recovery reservoir

When sourcing a radiator overflow tank, it's important to consider the specifications. These include:

• Capacity

Overfill tanks have different capacities. Buyers should select a tank that matches the needs of the vehicle. For larger vehicles with powerful engines, a radiator coolant overflow tank with a high capacity is preferable.

• Material

Coolant recovery tanks are often constructed from various materials like Polyethylene and Polycarbonate. They are preferred for their durability and compatibility with different types of coolants.

• Mounting Options

Coolant recovery tanks can be mounted in various ways. Some have brackets for easy attachment to the fan shroud. The fan shroud is located on the radiator's cooling fan. Other tanks have a flange at the bottom where the bolt passes through to secure the tank.

• Inlet and Outlet Size

Coolant recovery tanks have different inlet and outlet sizes. This allows for compatibility with various cooling system configurations.

• Visibility

It is good to go for tanks that have a transparent side. This allows the driver to check the coolant level without having to remove the cap.

• Pressure Rating

Choose a tank that can withstand the pressure of the cooling system. Most tanks are designed to handle pressures of up to 15 PSI.

Regular inspection of the coolant recovery tank will help detect any potential issues. Look for signs of cracks, leaks, or damage to the tank. Check the mounting brackets to ensure they are secure and in good condition. Replace the tank if it has developed damage. This could cause it to leak and allow coolant to escape, leading to overheating.

It's also important to check the hoses that connect the tank to the cooling system. Look out for signs of wear, cracks, or leaks. Ensure the hoses are properly routed and not kinked, as this could restrict the flow of coolant.

Inspect the tank's cap for signs of wear, cracks, or damage. The cap is important as it maintains the pressure in the cooling system and prevents coolant loss. If the cap is faulty, replace it with a new one of the same specifications.

Regularly check the coolant level in the recovery tank and top up if necessary. Use the recommended type of coolant for the vehicle. Mixing different types of coolants can affect the performance of the cooling system.

How to Choose Coolant Recovery Reservoir

Choosing the right antifreeze overflow tank is vital. Below are some of the factors to take into consideration.

• Size:

When choosing a coolant recovery tank, business buyers should consider the size of the car's engine. The reservoir tank should have the ability to hold the right amount of coolant to cool the engine. It should also have the ability to hold the correct volume of fluid to minimize overflow.

• Material:

When selecting a coolant recovery reservoir, business buyers should consider the materials the reservoir is made from. The material should be compatible with the coolant being used to store the engine. It should also be resistant to corrosion and heat. It should also be able to withstand extreme temperatures without getting damaged. The material used to make the rad overflow tank should be durable and long lasting.

• Pressure Rating:

When choosing a coolant recovery tank for the engine coolant system, business buyers should consider the pressure rating of the tank. The tank should be able to withstand pressure without cracking or breaking. It should also be able to maintain pressure in the cooling system for efficient cooling. Business buyers should choose a tank with a higher pressure rating to maintain the pressure in the cooling system and prevent overheating.

• Features:

Features to look out for when choosing a coolant recovery reservoir include level indicator, mounting brackets, and pressure caps. The level indicator is used to show the level of coolant in the tank. The mounting brackets are used to attach the tank securely to the car. The pressure caps are used to maintain pressure in the cooling system.

• Compatibility:

When choosing a coolant recovery tank, business buyers should consider the compatibility of the tank with the car's cooling system. The inlet and outlet ports should be compatible with the cooling system of the car. The tank should also be compatible with the type of coolant used in the car.

• Price:

Business buyers should consider the cost of the coolant recovery tank when making a purchase. They should compare the cost of the tank from different suppliers to get the best deal. However, they should avoid going for cheap tanks as they might be of low quality.

Q and A

Q1: How can one know that a coolant recovery tank is bad?

A1: Some common symptoms of a bad coolant recovery reservoir are an overheating engine, coolant leaks, a cracked or damaged reservoir, and a low coolant warning light.

Q2: What is the purpose of a coolant reservoir tank?

A2: A coolant reservoir, also known as a coolant overflow tank, is a small plastic or metal container used to store coolant. Its purpose is to collect the expanding coolant that heats up from the engine and circulates through the cooling system and then route it back to the cooling system once it is cooled off.

Q3: Should a coolant reservoir be full?

A3: Yes, the coolant level in the reservoir should be kept close to the full mark to ensure the cooling system is operating correctly. If the level drops below the minimum, it can cause overheating issues or damage to the engine.

Q4: How does a coolant reservoir work?

A4: The coolant reservoir is connected to the cooling system of the engine through a small hose. When the engine is running, the coolant circulates through the system. As the coolant heats up, it expands and flows into the reservoir through the connecting hose, thus maintaining the pressure in the system. Once the engine cools down, the coolant is drawn back into the system from the reservoir through a second hose, completing the cycle.
