Cold Weather Challenges for Volvo CE Machines
Operating Volvo CE machines in cold climates — below 0°C — requires specific preparation to prevent costly damage. Cold temperatures affect hydraulic oil viscosity (dramatically increasing flow resistance at startup), battery capacity (reduced by 30–50% at -20°C), diesel fuel (risk of waxing and gelling below -15°C), and coolant (freeze risk if SCA or antifreeze levels are inadequate). VMP Spares stocks all the cold-weather preparation parts and fluids for Volvo CE machines.
Pre-Winter Preparation Checklist
| System | Check / Action | Temperature Threshold |
|---|---|---|
| Coolant | Test antifreeze concentration — target -40°C protection | Below -25°C ambient |
| Hydraulic Oil | Switch to VG32 or winter grade hydraulic oil | Below -10°C ambient |
| Engine Oil | Switch to 5W-40 or 0W-40 multi-grade | Below -20°C ambient |
| Battery | Test CCA capacity — replace if <70% of rated CCA | Below -10°C ambient |
| Fuel | Switch to winter diesel (cloud point -20°C or lower) | Below -5°C ambient |
| Fuel Filter | Fit fuel heater or replace with cold-weather element | Below -10°C ambient |
| Grease | Switch to Arctic grade (NLGI 1) on all nipples | Below -20°C ambient |
| Block Heater | Verify engine block heater function | Below -15°C ambient |
| Water Separator | Check and drain — ice can block fuel supply | Below 0°C ambient |
Cold Start Procedure — Step by Step
Cold starting a Volvo CE machine at temperatures below -10°C requires a specific procedure to avoid hydraulic pump cavitation and engine damage. The Volvo recommended procedure is: start the engine and allow it to idle for 5–10 minutes without load until coolant temperature reaches 40°C, then cycle the hydraulic controls gently (boom up/down, swing left/right) at low speed for 5 minutes to warm the hydraulic oil before full operation. Never apply full hydraulic load with cold, thick oil — this causes pump cavitation and can score pump internal surfaces.

Glow Plugs & Cold Start Aids
Volvo CE diesel engines use glow plugs for cold starting. Glow plug failure is often silent — the engine cranks but struggles to fire in cold conditions. Testing each glow plug individually with a multimeter (cold resistance should be 0.5–1.5 Ω) is recommended as part of pre-winter preparation. On more modern engines with grid heaters (intake air heating), the grid heater element and relay should also be tested.
| Engine | Glow Plug OEM Numbers | Qty / Engine |
|---|---|---|
| D6E (4-cyl) | 20584050, 20584052 | 4 plugs |
| D7E / D8K (6-cyl) | 20584060, 20584062 | 6 plugs |
| D12D / D13H (6-cyl) | 20584070, 20584072 | 6 plugs |
| D11K / D13K Stage V | 22148020, 22148022 | 6 plugs + grid heater relay |
