What Are the Most Common Causes of Truck Radiator Failure?

When a truck radiator fails, the most common cause is a clogged radiator. If you are a truck driver or own a logistics company, you know how much trouble a failed truck radiator can cause you. In this blog, we'll tell you why your truck's radiator clogs and how to avoid and fix the problem. Hope this article can help you.

• The function and principle of truck radiator

When the engine of the truck is working, the function of the radiator is to reduce the temperature of the coolant through the cooling of the circulating water in the radiator, so as to maintain the normal operating temperature of the engine. The radiator is one of the main components of your truck's cooling system. It consists of a large number of tubes and fins, most of which are made of metal materials, most of which are made of aluminum alloy materials.

The radiator works by using cool air from the radiator to lower the temperature of the engine coolant. The radiator is a heat exchanger that contains coolant. As the heat transfer and heat conduction part inside the car, the car radiator plays a vital role in the car.

• Causes of a clogged truck radiator

1. Too much rust has accumulated in the pipeline, which will block the pipeline. When water flows in a truck radiator, the water creates a vortex in the pipes, which causes rust and impurities in the pipes to be stirred and flow with the water. If the water in your truck's radiator contains too much rust, it can build up in the pipes and eventually clog them.

2. If there is no cleaning for a long time, the scale in the hot water will continue to adhere to the radiator, which will cause many impurities in the radiator. As the water in the truck's radiator flows, the scale in the pipes will be stirred up and flow into the radiator with the water. If the water in your truck's radiator has too many impurities, those impurities can build up in the radiator and end up with a lot of impurities in the radiator.

3. After the scale falls off, it will block the water channel of the radiator of the water tank, and it is difficult to remove it by ordinary methods.

• How to Avoid a Clogged Truck Radiator

1. Regularly check the truck radiator for impurities and rust. The main thing is to check the appearance of the truck radiator, water tank, coolant, fan and water pump for impurities and scale.

2. Regularly clean the truck radiator. Regularly clean the truck radiator from dust, impurities, etc. to reduce the risk of clogging.

3. Use high quality antifreeze. Use long-term anti-rust antifreeze produced by regular manufacturers and in line with national standards to avoid corrosion of truck radiators.

4. Use soft water. Hard water needs to be softened before use to avoid blockage of truck radiators caused by scale.

• How to Check and Maintain Your Truck Radiator

1. Check the coolant level. In normal use, the coolant level should be checked at least once a month. If the climate is hot, the inspection frequency should be more. During inspection, the diesel engine should be at normal operating temperature, observe the liquid level of the coolant in the expansion tank, and the liquid level should be between the marks of "FULL" and "ADD" (or between the marks of "GAO" and "DI").

2. Sealing test. After the radiator is cleaned, check whether it is sealed. When checking, block the water inlet of the radiator with a wooden plug or a rubber stopper, seal the water inlet with a special cover after filling up the water, and pump air from the drain pipe to the radiator with an air pump; Blow air from the water inlet to increase the pressure inside the radiator. If there is a leak in the radiator, water will seep out from the leak and mark the leak.

3. Radiator repair. When the radiator needs to be repaired, we need to replace the upper and lower water chambers, dredge the heat dissipation core, calibrate the core, thoroughly remove the dirt in the upper and lower water chambers and the core, and weld the upper and lower water chambers as required. In this way, your truck will be able to keep working normally in high temperature environment.

4. Check the appearance of the radiator, water tank, etc. for impurities and rust.

5. When maintaining the radiator, the front grille can be removed to clean the radiator. Professional cleaning agent and water can be used to clean the flying catkins, floating dust and the interior of the radiator.

• How to choose the right coolant

1. The freezing point of the cooling liquid should be 10-15°C lower than the local minimum temperature, and the boiling point is usually 110°C above zero, so as to ensure the better performance of the cooling liquid.

2. The ethylene glycol in the cooling liquid must reach 89.86% in the national standard.

3. Each model has a dedicated coolant, and the merchant should be informed in advance when purchasing.

When a truck radiator fails, one of the most common causes is a clogged radiator, which in turn affects the normal operation of the vehicle. Therefore, after understanding the cause of the truck radiator failure, it is necessary to maintain it in time and check it regularly.

FAQs

Q1: What are the other reasons for truck radiator failure?

Common causes of truck radiator failures include failed water pumps, clogged radiators, radiator leaks, and inaccurate thermometers.

Q2: What are the reasons for truck radiator leakage?

The water pipes, radiators and other parts of the cooling system are broken, which is an external leakage; there is also leakage of the cylinder head gasket, which is an internal leakage.

Q3: What are the reasons for the failure of the truck radiator water pump?

There is a lot of dirt on the outside of the water tank, the coolant level in the water tank is low, there is debris inside the coolant, and the fan, water pump, and thermostat can also fail.
