Mitsubishi radiator expansion tank

Types of Mitsubishi Radiator Expansion Tank

The Mitsubishi radiator expansion tank is a vital component of the radiator system that holds excess coolant. This coolant is released when the engine heats up. When the engine cools down, the expansion tank takes in the coolant back. The tank ensures a constant supply of coolant. It also maintains pressure in the cooling system. The tank is made of strong plastic material. There are various models of Mitsubishi radiator expansion tanks. They include:

• Mitsubishi Outlander expansion tank

  The Outlander has a coolant reservoir on the driver's side near the wheel. The expansion tank holds excess coolant. This coolant is released when the engine heats up. The tank takes in the coolant when the engine cools down. It also maintains pressure in the cooling system.

• Mitsubishi Lancer radiator expansion tank

  Like other Lancers, the Lancer has a coolant reservoir on the driver's side near the wheel. The expansion tank holds excess coolant and takes in coolant when the engine cools down. It also maintains pressure in the cooling system.

• Mitsubishi Eclipse radiator expansion tank

  Like other Eclipses, the Eclipse has a coolant reservoir on the driver's side near the wheel. The expansion tank holds excess coolant and takes in coolant when the engine cools down. It also maintains pressure in the cooling system.

• Mitsubishi ASX radiator expansion tank

  Like other ASX models, the ASX has a coolant reservoir on the driver's side near the wheel. The expansion tank holds excess coolant and takes in coolant when the engine cools down. It also maintains pressure in the cooling system.

• Mitsubishi Pajero radiator expansion tank

  Like other Pajero models, the Pajero has a coolant reservoir on the driver's side near the wheel. The expansion tank holds excess coolant and takes in coolant when the engine cools down. It also maintains pressure in the cooling system.

Specifications and maintenance of the Mitsubishi radiator expansion tank

Manufacturers of Mitsubishi radiator expansion tank have different designs and models of the tanks to suit various vehicles and clients' needs. Here are some general specifications of the tanks.

• Material:

  The expansion tank is made from high-quality materials like polyethylene plastic. The material used to manufacture the tank is durable and can withstand the temperature and pressure conditions of the cooling system.

• Capacity:

  The capacity of the expansion tank can range from 2 to 4 liters. The capacity of the tank is designed to accommodate the coolant volume and the coolant's thermal expansion in various vehicle models.

• Dimensions:

  The dimensions of the tank vary with the design and model. Generally, the expansion tank has a height of 300mm, a diameter of 80mm, and a weight of 0.5kg. The expansion tank's dimensions are essential since they determine the tank's fit in the vehicle's engine bay.

• Pressure rating:

  The expansion tank has a pressure rating of 100kpa, which is equivalent to 1bar. The pressure rating is important because it must be compatible with the cooling system's pressure settings.

• Connection size:

  The expansion tank has various connection sizes, including 10mm, 15mm, and 20mm. The connection sizes include the inlet and outlet ports, which need to be compatible with the cooling system's hoses.

• Cap type:

  The cap of the expansion tank is a pressure relief cap. The cap has a pressure rating of 110kpa, which is equivalent to 1.1 bar. The cap type is important since it controls the pressure of the cooling system.

Here are some general guidelines for maintaining the radiator expansion tank.

• Check the expansion tank for any signs of damage or leaks. Any damage or leaks should be fixed immediately to avoid further damage to the radiator.
• When replacing the radiator, it is important to replace the radiator cap as well. This is because the radiator cap controls the pressure of the cooling system.
• Ensure that the tank is filled with the proper coolant according to the manufacturer's specifications. The coolant level should be checked regularly and topped up if necessary.
• Inspect the hoses connected to the expansion tank. Ensure there are no signs of damage or leaks. The hoses should be replaced after every five years.
• Wash the expansion tank and remove any debris and dirt to avoid damage to the tank.
• Visit a mechanic to have the cooling system pressure tested to check for any leaks and the expansion tank's condition.

How to Choose a Mitsubishi Radiator Expansion Tank

Choosing the right expansion tank for a Mitsubishi vehicle requires careful consideration of several factors to ensure compatibility, performance, and durability.

• Compatibility: The expansion tank must be compatible with the make, model, and year of the Mitsubishi vehicle. This guarantees that it fits perfectly and functions properly. When selecting the expansion tank, consider the vehicle's cooling system specifications and design.
• Quality and reliability: The quality and reliability of the expansion tank are vital for its long-term service. Choose expansion tanks made from durable materials that can withstand high temperatures and pressures. A high-quality expansion tank minimizes leaks and failures, maintaining consistent performance.
• Brand and supplier: Consider the brand and supplier when selecting an expansion tank. Well-known brands that offer cooling system components have proven quality and reliability. Find suppliers with good reviews and customer satisfaction records. Suppliers with a reputation for timely delivery and good customer service are also ideal.
• Price and warranty: Determine the budget for the expansion tank. While it is not advisable to compromise on quality, some suppliers offer competitive prices. Consider the warranty offered by the supplier or manufacturer. A good warranty acts as a guarantee for the quality and reliability of the expansion tank.
• Installation and maintenance: when selecting the expansion tank, consider the ease of installation and maintenance. Some expansion tanks are designed for simple installation and removal, which saves time and costs during replacement. Also, consider the maintenance needs of the expansion tank. Choose tanks that are easy to clean and inspect, ensuring optimal performance.

How to DIY and Replace Mitsubishi Radiator Expansion Tank

Replacing a radiator expansion tank is a straightforward process that can be done with basic mechanical skills and hand tools. Here's a step-by-step guide on how to replace a radiator expansion tank:

• Step 1: Gather the necessary tools and materials.
• Step 2: Ensure the vehicle is on a level surface and the engine is cool. Engage the parking brake and open the hood to access the radiator expansion tank.
• Step 3: Use a screwdriver or socket wrench to remove the bolts or clips securing the expansion tank. Carefully lift the old tank out of its mounting location.
• Step 4: Transfer any sensors, hoses, or mounting hardware from the old tank to the new one. Ensure they are in the correct positions on the new tank.
• Step 5: Position the new radiator expansion tank in its mounting location and secure it with bolts or clips.
• Step 6: Start the engine and let it run for a few minutes to warm up. Check for leaks around the hoses and connections. If there are any leaks, tighten the clamps or connections as needed.
• Step 7: Open the hood and carefully remove the cap from the new expansion tank. Pour the recommended coolant into the tank until it reaches the full level. Replace the cap securely.
• Step 8: Start the engine and let it run for a few minutes with the heater on high. This will help circulate the coolant and remove any air from the system.
• Step 9: Stop the engine and allow it to cool down. Once cooled, check the coolant level in the expansion tank and add more coolant if necessary to bring it to the full level.
