Preparing Your Machine for the Cold Season: A Checklist for Uninterrupted Operation

✅ 1. Check the coolant (antifreeze) level

A high-quality coolant is essential for protecting the engine during the cold season.

Komatsu genuine antifreeze:

• delivers optimal protection in extreme temperatures,

• prevents corrosion within the cooling system,

• keeps the engine operating in normal parameters.

✔ Check coolant level and concentration
✔ Top up only with compatible products

This is also the right time to check the radiator and water pump, to prevent coolant loss or overheating.

✅ 2. Inspect the filters

Air and fuel filters directly impact engine start-up and fuel consumption.

• The fuel filter must be checked to prevent water accumulation (which can freeze during winter)

• A clean air filter ensures smooth engine breathing and easier starts

❗ Clogged filters lead to harder engine starts and increased fuel consumption.

✅ 3. Clean the chassis and undercarriage area

Accumulated mud and debris:

• increase rolling resistance,

• accelerate corrosion,

• reduce overall machine efficiency.

✔ Regular cleaning extends component lifespan
✔ Reduces fuel consumption

✅ 4. Check tire pressure

Cold air causes tire pressure to drop — by up to 0.2 bar or more.

Incorrect pressure results in:

•  5–15% higher fuel consumption
•  uneven tire wear
•  reduced traction

✔ Check pressure when tires are cold
✔ Adjust according to manufacturer recommendations

✅ 5. Inspect the battery and electrical system

Low temperatures reduce battery capacity and make engine start-up more difficult.

What to check:

• Clean battery terminals (no oxidation)

• Inspect alternator and cables for deposits or corrosion

• Ensure all connections are tight and secure

A properly maintained battery ensures reliable engine starts, even in subzero temperatures.

✅ 6. Use lubricants suited for cold weather

In low temperatures, oils with incorrect viscosity become thicker and circulate less efficiently.

✔ Use engine and hydraulic oils with winter-grade viscosity
✔ Genuine Komatsu lubricants ensure faster start-ups and optimal component protection
✔ Follow the maintenance schedule to prevent wear caused by insufficient lubrication
