Introduction: The Importance of Cold Start Performance in Excavators
Cold start issues are a common challenge for many construction and heavy machinery operators, particularly in regions that experience freezing temperatures. Excavators like the Volvo EC140B are no exception. Designed for a variety of tasks, from digging trenches to lifting heavy loads, the EC140B is built for durability. However, when temperatures dip, starting the engine can become problematic. This article explores some of the common causes of cold starting issues in the Volvo EC140B, as well as solutions and preventative measures that can help ensure reliable operation even in the harshest winter conditions.
Why Cold Start Problems Occur in Excavators
Cold weather can be harsh on machinery, especially on diesel engines. When the temperature drops, several factors contribute to the difficulty in starting equipment like the Volvo EC140B:
In cold regions, such as parts of Canada and Scandinavia, the cold weather presents a unique set of challenges for operators of heavy machinery. For example, a contractor working on a construction site in the Canadian Rockies found that their Volvo EC140B was having difficulty starting in winter. After several attempts, they traced the issue to fuel line gelling and a battery that had lost some of its charge due to sub-zero temperatures. By using the proper fuel additives, replacing the battery, and ensuring the glow plugs were working correctly, the operator was able to solve the issue and get the machine back to work.
Similarly, in Norway, a fleet of excavators operating in freezing temperatures regularly uses engine block heaters as part of their winter maintenance routine. This simple investment has significantly reduced the number of cold-start issues and saved the company on costly repairs.
Conclusion: Ensuring Your Volvo EC140B Starts Smoothly in Cold Weather
Cold start issues are a challenge that many excavator owners face during the winter months, particularly in cold climates. For the Volvo EC140B, maintaining the battery, glow plugs, and fuel system, as well as using the appropriate engine oil, can make a significant difference in the machine’s ability to start on time. Preventative maintenance, along with a few key tools and additives, can help ensure that your Volvo EC140B performs reliably even in the most frigid conditions.
With proper care and attention, your Volvo EC140B can continue to work effectively through the winter season, avoiding costly downtime and keeping your operations running smoothly.

Why Cold Start Problems Occur in Excavators
Cold weather can be harsh on machinery, especially on diesel engines. When the temperature drops, several factors contribute to the difficulty in starting equipment like the Volvo EC140B:
- Viscosity of the Engine Oil: Cold temperatures cause the oil in the engine to thicken, making it harder for the engine to turn over. This can increase the strain on the starter motor and cause sluggish or unsuccessful starts.
- Fuel Quality: Diesel fuel can gel in very cold temperatures, causing it to become less combustible. If the fuel lines freeze or become blocked, this can prevent the engine from starting.
- Glow Plugs and Fuel Injectors: In diesel engines, glow plugs help to heat the combustion chamber during startup in cold conditions. Faulty glow plugs or issues with the fuel injectors can cause the engine to struggle to start or not start at all.
- Battery Weakness: Batteries lose their efficiency in cold weather, and a weakened battery may not provide enough power to crank the engine over. Even with a healthy battery, the cold can reduce the voltage, making it harder to start.
- Slow Cranking: The engine turns over slowly, taking longer than usual to start. This is often the first sign that something is preventing the engine from starting quickly.
- Engine Won’t Start: The engine fails to fire entirely, despite the starter motor running. This could be due to a lack of fuel flow or issues with the ignition system.
- Excessive Smoke: If the engine does start but produces more smoke than usual, it could indicate incomplete combustion caused by fuel problems or issues with the glow plugs.
- Battery Health: A weak or dead battery is one of the most common causes of cold starting problems. As the temperature drops, the chemical reactions within the battery slow down, reducing its ability to hold a charge and supply power to the starter motor.
Solution: Inspect the battery for signs of corrosion on the terminals and ensure that the battery is fully charged. If the battery is old or weak, consider replacing it with a new, high-performance battery designed for cold climates.
- Glow Plug Malfunctions: The glow plugs in the Volvo EC140B play a crucial role in ensuring smooth cold starts. If they’re faulty, the engine may struggle to start or fail altogether.
Solution: Test the glow plugs and replace any that are defective. You may also want to check the wiring connections to ensure proper operation. A faulty relay or fuse could also prevent the glow plugs from heating up properly.
- Fuel Line Freezing: In cold conditions, diesel fuel can gel, causing it to block the fuel lines or prevent proper fuel flow. This can prevent the engine from starting or running smoothly.
Solution: Use anti-gel additives in the diesel fuel to prevent it from freezing in cold weather. Additionally, ensure that the fuel lines are properly insulated and free from cracks that could let in moisture, which could freeze.
- Thick Engine Oil: Cold temperatures cause engine oil to thicken, which makes it harder for the engine to turn over.
Solution: Use winter-grade oil that is designed for colder climates. Winter-grade oils have lower viscosity, which allows the engine to turn over more easily in cold weather.
- Fuel Filter Issues: The fuel filter can become clogged with dirt, water, or debris, which is often exacerbated in colder weather. A clogged filter can impede fuel flow and cause starting issues.
Solution: Check the fuel filter for blockages or contamination, and replace it if necessary. Regularly replacing the fuel filter is essential for maintaining optimal engine performance.
- Fuel Injector Problems: If the fuel injectors are clogged or malfunctioning, they may fail to deliver the correct amount of fuel to the engine, which can result in starting problems.
Solution: Clean or replace the fuel injectors as needed. You can also use fuel injector cleaner to help restore proper fuel flow, especially if the injectors have become gummed up over time.
- Pre-Heat the Engine: Consider using a block heater or oil heater to warm up the engine before starting it. This will reduce the strain on the engine and battery and help to improve the starting performance.
- Park in a Warmer Area: Whenever possible, park the excavator in a warmer environment such as a garage or heated building overnight. This can help prevent freezing issues and ensure that the machine starts more easily in the morning.
- Regular Maintenance: Regularly maintain the excavator by checking the oil, fuel system, and electrical components. This can help prevent issues before they become significant problems, particularly during the colder months.
