15 Essential Winterization Tips for Construction Equipment

Winter is approaching, and while you might enjoy the cold, your construction equipment certainly does not. Cold temperatures can cause a variety of issues for machinery, from sluggish engines to frozen fluids. Proper winterization is crucial to ensure your equipment operates efficiently and stays in good condition during the colder months.

1. Routine Inspections

Before the first cold snap or after any extended downtime, inspect your equipment to prevent issues later on. Be sure to:

• Inspect each light

• Check windshield wipers

• Top off all fluid levels

• Ensure heater functionality

• Lubricate engine components

• Inspect the body for wear, dents, or dings

• Check glass and mirrors

• Test brake functionality

• Grease joints and hinges

2. Change to Winter Grade Fuel

Switching to winter-grade fuel helps your machinery run smoothly in low temperatures. This type of fuel is specially formulated to prevent freezing in cold weather.

3. Change the Engine Oil

Engine oil becomes thicker in colder temperatures, making it harder to flow. Switching to multi-grade oil before the cold sets in ensures smoother operation and better performance during winter months.

4. Inspect the Engine

Start your engine and allow it to reach operating temperature before use. This prevents exhaust and intake sticking. Also, check the condition, placement, and tension of the fan belts and ensure the V-pulley belts are in good working order. Over- or under-tensioned belts are more prone to slipping or increased wear.

5. Change the Filters

Clogged fuel and air filters are an engine’s worst enemy. If you’ve changed the fuel type for winter, be sure to inspect and replace filters as needed. Additionally, drain the water trap before the first freeze of the season.

6. Battery Maintenance

Cold temperatures drain battery performance. Here’s how to keep your battery in top condition:

• Store batteries indoors, at room temperature if possible

• Batteries lose up to 65% of their cranking capacity at 32°F

• Charge batteries before use and maintain them at 75% capacity or higher

• Clean dirt and debris from the battery

• When storing, keep batteries upright and do not stack them

• If storing for over 10 days, disconnect the ground cable

• Check on stored batteries every 4-6 weeks

7. Check the Coolant

Ensure the coolant is clean and free of bubbles. The coolant should be about an inch above the radiator core, and the mix should be 50/50 for sub-zero temperatures. For less severe temperatures, you can use more water in the mixture. Always use coolant designed for cold weather.

8. Check Hydraulics

Replenish hydraulic fluids and ensure all cylinders are properly greased and functioning. Lubricate the suction chamber and filters, and check the main hydraulic pump for leaks. Ensure the hydraulic fluid is rated for colder temperatures.

9. Check Hoses

Inspect hydraulic hoses for cracks or swelling. If a hose feels brittle or too soft, it might need replacement. Brittle hoses indicate heat exposure, while soft hoses suggest contact with lubricants, which can cause them to fail under pressure.

10. Inspect Tires

Cold weather makes it harder for tires to hold air. Inflate tires in warmer temperatures when possible to improve the bead seal. Consider using nitrogen, which helps prevent ice crystal formation inside tires.

11. Inspect the Undercarriage

Undercarriage issues can be exacerbated by snow and ice. Inspect rubber and steel tracks to ensure they still provide adequate traction on snow and ice. If your machine has been buried under snow, it’s wise to have a mechanic inspect the undercarriage to ensure everything is functioning properly.

12. Store the Machine Properly

Proper storage helps avoid damage caused by freezing conditions:

• Store equipment indoors in an enclosed space

• Keep fluids at room temperature to prevent freezing

• Store detachable parts separately to prevent rust and joint damage

13. Block Heaters

Block heaters are incredibly useful for warming the engine and hydraulic fluids, making it easier for the machine to reach operating temperature and reducing strain on cold machinery.

14. Use Starting Fluid If Necessary

Use starting fluid only when necessary as it is highly flammable. Store it in a safe location, away from the machine’s cab, to avoid the risk of ignition.

15. Correct Storage of DEF

Diesel Exhaust Fluid (DEF) requires special care in cold weather. DEF freezes at around 12°F, so be sure to store it properly:

• If DEF freezes, thaw it carefully to avoid damage

• Always store DEF in a location that stays above freezing temperatures

Conclusion

Proper winterization and maintenance are essential to keep your construction equipment running smoothly through the colder months. By following these tips, you can prevent unnecessary downtime and costly repairs while ensuring that your machines are ready for the challenges of winter.
