For the upkeep of heavy machinery like excavators, bulldozers, and diesel engines, the radiator is crucial. It has a direct impact on the equipment's lifespan and performance and aids in the engine's maintenance at the ideal temperature. You can better handle equipment maintenance if you know "how the radiator cools the engine," "how to determine the size of the engine radiator," and "how to clear the engine oil in the radiator." MyMROmarts will examine each of these problems in detail and an understandable manner in this post.

How Does a Radiator Cool an Engine?

The radiator is a core component of the engine cooling system. Its working principle is based on liquid circulation and heat exchange.

1. Coolant circulation

When the engine is running, it generates a lot of heat. The coolant absorbs heat from the engine and flows into the radiator. In the radiator, the coolant passes through multiple rows of small pipes. The outside of the pipes is covered with metal fins, which can also increase the heat dissipation area of the radiator.

2. The role of air

When the coolant flows through the radiator, the fan blows air through the radiator fins to take away the heat. In this way, the coolant is cooled. This process is circulated continuously to keep the temperature of the diesel engine stable.

3. Application in heavy equipment

The diesel engine radiators are widely used in heavy equipment because of their efficient cooling capabilities. For example, excavator radiators and bulldozer radiators can cope with the heat under high load operation.

How to Size an Engine Radiator?

Choosing the right radiator for your heavy equipment is important, especially for heavy engines like diesel engines.

1. Calculate the heat load

The heat load of your heavy equipment is an important basis for radiator design. The heat load is usually determined by the engine's power (in kilowatts or horsepower) and the operating environment.

2. Check the radiator's capacity

The radiator's capacity should match the engine's coolant flow and heat transfer needs. Insufficient capacity can cause the engine to overheat. A radiator with too much capacity will increase costs and installation difficulties.

3. Consider the equipment's operating environment

If your heavy equipment is operating in a high-temperature environment for a long time, the radiator needs a larger cooling capacity. For example, excavator radiators and bulldozer radiators are often equipped with more efficient cooling systems.

4. Ask for professional advice

If you are not sure how to choose, you can contact professional suppliers, such as MyMROmarts online store. We have a variety of radiators suitable for heavy equipment, including excavator radiators and other models.

How to Clean Engine Oil out of Radiator?

Engine oil entering the radiator is caused by a cooling system failure. For example, the cylinder gasket is damaged or the oil cooler is leaking. Cleaning the oil in the radiator is a process that requires patience.

1. Drain the coolant and oil mixture

First, turn off the engine and put the cooling system in a cool state.

Open the radiator drain valve and completely drain the coolant and the mixed oil.

2. Rinse with a cleaning agent

Choose a professional radiator cleaner.

Mix the cleaning agent with warm water pour it into the radiator and let it soak for 15-30 minutes.

3. Rinse thoroughly

Rinse the radiator thoroughly with clean water until the drained water is clear.

4. Refill the coolant

Check whether the system is repaired and refill the coolant after troubleshooting.

5. Regular inspection

To avoid similar problems from happening again, check the cooling system regularly. Especially diesel engine radiators and other heavy equipment such as bulldozer radiators and excavator radiators.

Routine maintenance and proper selection of radiators are critical to the performance and life of your heavy equipment. Learn how the radiator cools the engine, how to size it, and how to clear engine oil from the radiator. Doing so can prevent equipment failure and greatly improve your productivity.
