Excavator radiator – The Ultimate FAQ Guide


This guide will help you collect information about excavator radiators.

It includes excavator radiator, cost, benefits, working principle, excavator radiator sizes, excavator radiator valves, maintenance requirements, and much more.

This guide is a useful and rightful source of information either you are a beginner or a professional in this field.

1.    What does an excavator radiator do?


The main purpose of the excavator radiators is to cool down the engine in such construction machines as the excavator, prevent overheating, and ensure proper functioning in service.

It is in charge of removing excess heat from the surrounding environment from the engine.

Excavator Radiator

Excavator radiator production is a breakthrough in the hydraulic equipment industry.

You will find an excavator radiator most commonly within the engine compartment, usually on the front of your engine.

The excavator radiator’s size varies depending upon the size and model of an excavator because the amount of heat generated is more in large size excavators compared to the small size excavators.

2.    What are the most efficient excavator radiators?


The term efficient means how good your excavator radiator is in keeping your excavator cool.

Electric radiators are one of the most energy-efficient devices available.

They are ‘100% efficient’ for this reason.


Since almost all the electric current utilized by excavator radiators is transformed into heat, they are incredibly efficient.

The most efficient excavator radiators have larger tubes and fins.

These allow a greater heat transfer rate, making the radiator more efficient and powerful.

They are also designed with larger tubes for higher temperatures.

The radiator design is critical to maximizing efficiency and performance while minimizing size, weight, and overall cost.

3.    How long should an excavator radiator last?


The life of an excavator radiator varies on the application and location that you are using it in. These radiators are exposed to medium or high temperatures.

An excavator radiator should probably last about three years before it needs to be replaced, but certain circumstances can change that estimate.

The way to maximize the life of your radiators is to keep them maintained, and high-quality coolant must be used in them.

By following proper maintaining procedures, an excavator radiator can last up to 8 to 10 years.


Choosing a good quality excavator radiator and cooling fans are important, especially for excavator engines, as they operate through long hours without being stopped and have a comparatively longer life.


4.    How much an excavator radiator cost?


The cost of an excavator radiator depends upon several factors.

These primary factors include material (they might be made from aluminum, magnesium, copper, or heat-tolerant steel) used in the manufacturing of an excavator radiator, size of the radiator, the efficiency of the radiator, the weight of the radiator, design of your excavator radiator, etc.


In general, the cost of an excavator radiator $150 to $600 per piece.

For instance, the price of an aluminum cooling excavator radiator lies in the range of $175 to $290 per piece.

A high-quality excavator radiator has a higher cost, and a low-quality excavator radiator has a much lower price.

5.    What should I look for when buying an excavator radiator?


While buying an excavator radiator, the top considerations are its liquid capacity and the type of tubes it uses.

Liquid capacity refers to the amount of liquid it can hold, and this is measured by the number of gallons a radiator keeps.

When buying an excavator radiator

The more liquid a radiator holds, the larger the hours it can run before needing to be refilled.

The type of tubes an excavator radiator uses refers to the kinds of metals used in producing the tubing.

Two main types of tubing are widely used, including copper and aluminum, each having its benefits.

Copper radiators tend to be more expensive than aluminum radiators.

6.    What are the three main causes of excavator radiator failure?


The three main causes why an excavator radiator gets fails are described below:

The number one cause of radiator failure is incorrect water chemistry.

Water alone will not clean or condition radiator parts. A coolant is needed to serve the purpose.

Excavator Radiator Failure

Hot water and organic debris must be flushed from the radiators during a flush period.

If possible, running the engine with hot water and a radiator cleaner will help a great deal.

Secondly, regeneration cooled evaporator blocks are prone to failures due to leaks into the block resulting in oil contamination.

The third problem is poor air circulation around radiators. This is because the radiator fan is not working or performing its intended function.

7.    What are the components of the excavator radiator?

An excavator radiator comprises several parts. Some of the main features are listed below:

Components of Excavator Radiator

  • Radiator fans
  • Water pump
  • Water tank
  • Thermostat
  • Transmission oil cooler
  • Outer housing

Each part of an excavator radiator has a specific feature and application without which your excavator cannot perform the intended function.

A radiator can be an air-cooled radiator or a liquid-cooled radiator. You can use anyone depending on your need and the model of an excavator.

8.    Is it expensive to replace excavator radiators?


Yes or no, it depends upon the type of excavator radiator.

When your excavator’s radiators aren’t working properly due to damage, age, or just plain wear, it can be expensive to replace them in case if they cannot be repaired.

When you get a specific component or part of your excavator radiator repaired or repaired yourself, it saves you the extra cost to purchase or install a newer one.

While replacing the design of a radiator, you must consider its cost and production costs and how much radiators will save on water and fuel consumption.

9.    Can I change an excavator radiator without draining the system?


Yes, in an emergency or if the operating conditions in the machine are extreme, yes, it certainly may be possible to change an excavator radiator without draining the system.

However, as a general rule, you need to drain the system because of the potential for hidden blockages in the piping and safety reasons.

Change Excavator Radiator

There may also be some damage to connections that won’t be obvious during dismantling but could result in the new radiator’s failure.

A few specialty radiators for excavators and other large equipment can be removed with the engine at full operating temperature.

Most excavators are set up with little spaces between the engine and radiator, allowing you to remove the radiator without draining the system.

Smaller, special radiators may not allow this, and you may need to drain the system.

10.      What are the reasons an excavator radiator gets clogged?


An excavator radiator is usually clogged because of dirt and debris that enters inside it.

They get clogged because of foreign material in the radiator.

The rubber hose that attaches to the radiator’s water pump gets deterioration and cracks. That allows sand and mud to enter the radiator and clog it.

Excavator Radiator Clogged

This can be a problem in any age of diagnosis. This problem should be taken seriously and should be heightened as soon as possible to prevent more damage to your engine depending on the situation.

You can prevent clogging by flushing it frequently and see if any cracks allow for foreign material. If yes, then replace that component.

11.      What type of excavator radiator coolant should I use?


There are several different types of antifreeze coolant that can be used in vehicles. However, glycol-based coolants are the preferred types of coolants to use.

Most vehicles require the addition of coolant to the engine to maintain their internal temperature in the winter.

Types of Excavator Radiator

Vehicle manufacturers often recommend a 50/50 mix.


Radiator coolant is important to use as it protects the engine from overheating.

Coolant is vital for keeping an engine’s temperature under control.

Your engine needs to stay well-cooled, and this is why it will break down if the coolant is emptied.

The radiator coolant will typically need refilling when drained out or when traces of corrosion are noted on the radiator tubes.

12.      How does an excavator radiator work?


The working of an excavator radiator is explained below.

The radiator is installed close to the engine. Subsequently, the radiator is heated up by the heat produced by the engine.

The engine coolant or water flows utilizing tubes attached to the radiator where it gets heated and sent into the liquid tank.

The water gets hot and rises and, in its place, similarly cold water moves down due to the density differences.

The radiator fan — a small electric motor fitted to the radiator — spins on an axle, pulling air through the openings in the radiator.

The fan blowing air through the radiator is meant to cool it down and obtain heat from it.

13.      What is the role of thermostats in excavator radiators?


The thermostats have the function of controlling the temperature and flow ratios in the radiator system.

The main purpose is to prevent the overheat and boiling of the coolant system.

Thermostats are an important component in a radiator system.

Thermostats in Excxavator Radiator

The thermostat allows you to control the amount of cool fluid that circulates through the radiator. This, in turn, regulates the temperature of your engine.

Without thermostats, the excavator radiator will not be just a simple water vehicle, and it will be dangerous!

This means that thermal control of the excavator radiator is a key factor dictating its safe use.

14.      What are the benefits of an excavator radiator?


There are several benefits of an excavator radiator in an excavator. Some of the main excavator radiator benefits are listed below:

  • An Excavator radiator increases the efficiency of an excavator
  • Excavator radiator enhance your excavator lifetime
  • It removes excess heat from your excavator engine and controls the temperature of your engine
  • Excavator radiator reduces extra cost incorporation for engine repair

15.      Why my excavator radiator is producing noise?


There are several reasons why your excavator radiator is producing noise. Some of the main reasons are listed below:

  • The radiator can produce noise during the machine operation if the cooling water or oil is below the required temperature,
  • If the fan device that forced the air into the radiator is jammed by some foreign matter and thus cannot generate enough air pressure to force cool air into the radiator tubes,
  • If there is too much air bubble on a radiator pipe, they produce a rattling sound.
  • Excavator radiators usually produce noise because of dust, rust, and other bad stuff inside the radiator tubes.

16.      What do you mean by bleeding an excavator radiator?


Bleeding an excavator radiator means that you have to drain out the old coolant and replace it with a brand-new coolant.

Bleeding is also referred to as a process of purging air and water from the entire radiator system, including radiators, engine block, coolant tubes, radiator tank, and radiator grille.

Bleeding an excavator radiator

Bleeding an excavator radiator offers your service technicians the opportunity to recognize any obstructions in the system.

Some of the obstructions are as follows: flaking tin- sulfides and oxides; airlocks/bubbles; debris; water taps open; and over-pressurization.

When you operate an excavator for extended periods, it is necessary to bleed your excavator radiator to enhance the longevity and efficiency of your excavator radiator.

17.      What does excavator radiator insulation mean?


An excavator radiator insulation is a common term used by excavation professionals to describe the main function of all radiators.

Radiators are used to transfer heat produced from an engine or similar area to the atmosphere.

In simple terms, it’s an outer skin made from rubber, plastic, or some other material that’s applied to increase the longevity of the radiator.

18.      What do you mean by vertical excavator radiators?


Vertical excavator radiators are the ones that are installed in a standing position in excavators. Hence, they are commonly known as “vertical radiators.”

Vertical Excavator Radiators are designed for the cooling system of high-capacity, powerful and heavy motive power machines.

Vertical Excavator Radiators

In a vertical excavator radiator, the tubes through which water circulates are placed in an upright position in front of the engine.

These excavator radiators are recommended where horizontal more space is not available.

Vertical radiators play a vital role in ensuring that the thermal needs of the engine are met during all operations.

19.      How to clean your excavator radiator?


Cleaning your excavator radiator is an essential part of the proper maintenance and upkeep of your machinery.

There are a few different ways to approach cleaning your radiator.

The first involves draining radiators of their water and then adding a rust remover and flushing the system.

Cleaning of Excavator Radiator

This will clean out most of the corrosion and sediment buildup over time with the extreme temperatures that some radiators are exposed to.

The second option considers many excavators have very limited space in front of the radiator or do not have a convenient place to drain it.

This method is designed to partially remove most sediment and rust buildup without completely draining the radiator.

This is often used for projects where there is a lack of available

It is important to ensure that the radiator is cooled down before cleaning; otherwise, you may end up with burns on your skin.

20.      What are the maintenance requirements of an excavator radiator?


Maintenance requirements of an excavator radiator include initial checks on the various parts.

These include radiator hoses and fan belts.

The hoses must be in good condition without any bulging or tears, while the belts must be tight and free from cracks or signs of wear and tear.

Fan belts have to be changed immediately if they break down, as this could cause the failure of the radiator and other important engine parts. Also, the fan needs regular inspection.

You must keep the correct fluid level, ensure that the temperature is right, and make no leaks in your excavator radiator.

The maintenance requirements of excavator radiators are similar to automotive radiators in that they need to be cleaned and free of scale. Therefore, they require some expertise, including skills with steam cleaning.

21.      What are the signs that my excavator radiator is bad?


The following signs indicate that your excavator radiator is bad and in need of replacement are given below.

The first and most common thing you will notice is the water temperature steadily rising on your instrument panel.

Some of these signs include frequent coolant loss, an inoperative thermostat, leaking pilot tubes, or damaged hoses/adapters.

Your excavator radiator may get clogged due to the incorporation of foreign particles, which results in the hindered operation of your excavator radiator.

When you experience these signs, it is time to replace your old excavator radiator with a new one.

22.      What is the working principle used by excavator radiators?


Your excavator radiator work on the principle of density differences.

The water inside the radiator becomes hotter. As a result, it gets thinner and lighter in weight.

It moves upward due to its lighter weight.


On the other hand, the cold water is heavier and has a higher density. Therefore, this water lays down for heat exchanging.

The hot water moves behind the radiator fan and exchanges it through copper tubes with a radiator fan. As it becomes cold, it again comes down, and thus the cycle continues.

In this way, heat is removed from your engine through an excavator radiator.

23.      What materials are used in the manufacturing of an excavator radiator?


There are several materials used in the manufacturing of an excavator radiator. Some of the main materials are listed below:

  • Aluminum
  • Copper
  • Plastic
  • Cast iron
  • Stainless steel
  • Brass

Each material has its special applications and features based on hardness, durability, strength, heat exchanging properties, wear and tear, corrosion resistance, weight, and special characteristics.

Each material has variable cost depending upon the special features of that specific material.

When the materials with special features are employed in manufacturing your excavator radiator, the cost associated will also increase.

24.        What excavator radiator size do I need?


Whether you’re putting together a new machine or repairing a broken-down unit, knowing what radiator size you need is vitally important.

Many factors can affect the radiator size required for your particular model, including engine type, vehicle type, and several tubes, to name a few.

Excavator radiators are a crucial aspect of all excavator equipment.



However, it is important to choose the correct radiator size to help ensure that your excavator has the right running temperature and is comfortable for operation.

A properly sized radiator will also help prevent you from having to replace or repair your radiator regularly.

This can be determined by manually measuring both the height and width of each of the radiators being used in your machine.

Some of the widely used sizes are listed below:

Sr. No. Product Size (mm)
1 Excavator Radiator 400 × 400
2 Excavator Radiator 300 × 1000
3 Excavator Radiator 400 × 1200
4 Excavator Radiator 600 × 1200
5 Excavator Radiator 600 × 900

25.      How did excavator radiator valves work?


Excavator radiator valves are used for controlling and regulating the flow of fluid warm in the radiator system.

Excavator Radiator Valve

It can also be referred to as an engine coolant valve or as a steam switch valve.

Excavator radiator valves serve two functions.

  • First, they regulate the temperature of the engine.
  • Second, they regulate the flow of water in and out of the radiator.

The overall temperature, or pressure, is adjusted via a series of hydraulic actuators that control how much space there is between the slats so that only as much water can travel through them.

26.      Can I import an excavator radiator from China?


Yes, you can import excavator radiators from China.

Chinese excavator radiator manufacturers provide you with the highest quality excavator radiators at the lowest prices.

They also provide an option for buying excavator radiators on custom-made orders where you can choose the length, width, size, and material for each part of an excavator hammer that fits your needs.

It is an excellent choice to purchase from Chinese manufacturers as they provide various types of excavator radiators to choose from, and there is no limitation on order quantity.
