The Volvo EC210B LC is a popular tracked excavator that has earned a reputation for its reliability and durability in tough work environments. This machine is commonly used in construction, mining, and demolition projects, where it often faces harsh operating conditions. One key component in the EC210B LC’s engine system is the intake heater, designed to ensure efficient engine start-up, particularly in cold weather conditions.
However, like any other machine, the intake heater system on the EC210B LC may experience issues over time. If the intake heater is malfunctioning, it can lead to poor engine performance, difficult start-ups, and potential engine damage. This article will explore the common issues related to the intake heater, the symptoms of failure, and the steps you can take to troubleshoot and resolve these problems.
What is an Intake Heater and How Does It Work?
An intake heater is a crucial component in diesel engines, especially in machines like the Volvo EC210B LC. The purpose of the intake heater is to warm the air entering the engine’s intake manifold, making it easier for the engine to start in cold weather. Cold air can make it harder for diesel engines to ignite fuel efficiently, leading to rough starts, extended cranking times, and increased fuel consumption.
The intake heater in the EC210B LC works by using electrical heating elements to warm the intake air. This process not only improves starting but also reduces the amount of fuel required to reach optimal combustion temperatures, ultimately improving engine performance and longevity.
Common Issues with Intake Heaters on the Volvo EC210B LC
Despite its critical role in engine operation, the intake heater can experience problems, especially if the excavator operates in cold environments frequently. Below are the most common issues that can affect the intake heater on the Volvo EC210B LC:
1. Faulty Heater Element
The most common problem with the intake heater is a faulty heating element. These elements are designed to heat the intake air, but over time, they can wear out or become damaged, preventing them from functioning properly. A malfunctioning heater element can cause difficulty starting the engine, especially in cold temperatures.
Another common issue is a blown fuse or electrical problem within the intake heater circuit. Since the intake heater relies on electrical power to operate, a blown fuse or a damaged electrical connection can prevent the system from receiving power, rendering it ineffective.
Over time, the wiring and connectors that deliver power to the intake heater can deteriorate due to wear, moisture, or corrosion. Faulty connections can lead to poor power delivery, reducing the efficiency of the intake heater.
The intake heater relay is responsible for controlling the activation of the intake heater. If the relay is faulty or stuck in the "off" position, the heater will not operate, leading to cold starting issues.
The control module, which manages the intake heater system, can experience malfunctions due to electrical issues or sensor failures. If the module fails, it may not send the proper signals to activate the intake heater.
Sometimes, the issue with the intake heater is not the heater itself but a restriction in the air intake system. If the intake system is clogged or obstructed, the heater may not have enough airflow to function properly.
Diagnosing intake heater issues on the Volvo EC210B LC involves a systematic approach. Here’s how to proceed:
Step 1: Inspect the Heater Element
Start by visually inspecting the heater element for any visible signs of damage, such as cracks or burn marks. If the element appears damaged, it will need to be replaced.
Step 2: Check Fuses and Wiring
Inspect the fuses and wiring associated with the intake heater. Replace any blown fuses and repair any damaged wiring or connectors.
Step 3: Test the Relay
Use a multimeter to test the intake heater relay for continuity. If the relay is not functioning properly, replace it with a new one.
Step 4: Examine the Control Module
If the issue persists, check the control module for any fault codes. If the control module is malfunctioning, replace it with a compatible unit.
Step 5: Clear the Air Intake
Lastly, check the air intake system for restrictions or damage. Ensure that the intake air is flowing freely to allow the intake heater to function properly.
Conclusion
The intake heater is a vital component of the Volvo EC210B LC, particularly for ensuring reliable cold starts and optimal engine performance. By understanding the common issues that affect the intake heater system and following a thorough diagnostic process, operators can resolve these issues quickly and efficiently.
Regular maintenance and timely inspections of the intake heater system will not only prevent cold start issues but also contribute to the overall longevity of the engine. If problems persist despite troubleshooting, it may be necessary to consult a professional technician to perform more advanced diagnostics or repairs.
By addressing intake heater problems early, owners and operators can ensure their Volvo EC210B LC continues to operate smoothly, even in challenging weather conditions.

The most common problem with the intake heater is a faulty heating element. These elements are designed to heat the intake air, but over time, they can wear out or become damaged, preventing them from functioning properly. A malfunctioning heater element can cause difficulty starting the engine, especially in cold temperatures.
- Symptoms: The engine may take longer to start or fail to start altogether. You might also notice poor engine performance during the initial warm-up phase.
- Solution: Inspect the heater element for signs of damage or wear. If the element is faulty, it will need to be replaced. Ensure that the replacement part meets the manufacturer’s specifications for compatibility and performance.
Another common issue is a blown fuse or electrical problem within the intake heater circuit. Since the intake heater relies on electrical power to operate, a blown fuse or a damaged electrical connection can prevent the system from receiving power, rendering it ineffective.
- Symptoms: No power to the intake heater, which can lead to longer starting times or complete failure to start in cold weather.
- Solution: Check the fuse box for any blown fuses related to the intake heater system. If the fuse is damaged, replace it with a new one of the correct amperage. If the fuse blows again, it may indicate an underlying electrical issue, such as a short circuit or damaged wiring, that requires further investigation.
Over time, the wiring and connectors that deliver power to the intake heater can deteriorate due to wear, moisture, or corrosion. Faulty connections can lead to poor power delivery, reducing the efficiency of the intake heater.
- Symptoms: Intermittent starting issues or failure of the intake heater to activate when needed.
- Solution: Inspect all wiring and connectors related to the intake heater for signs of wear, corrosion, or loose connections. Clean or replace any damaged components to restore proper power flow to the heater.
The intake heater relay is responsible for controlling the activation of the intake heater. If the relay is faulty or stuck in the "off" position, the heater will not operate, leading to cold starting issues.
- Symptoms: The intake heater does not engage when starting the engine, resulting in difficult starts in cold weather.
- Solution: Test the intake heater relay for proper operation. If the relay is found to be faulty, it should be replaced with a new one to restore functionality.
The control module, which manages the intake heater system, can experience malfunctions due to electrical issues or sensor failures. If the module fails, it may not send the proper signals to activate the intake heater.
- Symptoms: The intake heater system remains inactive despite cold weather, leading to poor engine starts and potentially increased wear on the engine over time.
- Solution: If the control module is suspected of malfunctioning, diagnostic tools should be used to check for error codes or faults. In many cases, a replacement control module may be necessary to restore proper function.
Sometimes, the issue with the intake heater is not the heater itself but a restriction in the air intake system. If the intake system is clogged or obstructed, the heater may not have enough airflow to function properly.
- Symptoms: Reduced engine performance or incomplete combustion, along with cold starting difficulties.
- Solution: Inspect the air intake filters and hoses for any blockages or damage. Ensure that the intake system is clear and free of debris, allowing the intake heater to work effectively.
