⚠️ Early Access Notice

This guide is based on My Winter Car Early Access (December 2025). Block heater mechanics may be updated in future patches.

1. What is a Block Heater?

A block heater (also known as an engine preheater) is an essential device for cold weather driving in Finland. It keeps your engine warm when parked, making cold starts much easier and protecting your engine from extreme cold damage.

🔌

Engine Block Heater

Warms the engine block and coolant using external electrical power. Essential for reliable cold starts in Finnish winters!

Feature Details
Power Source External electrical outlet
What It Heats Engine block and coolant
Engine State Works with engine OFF
Cable Location Front of the car
🔋 How It Works

The block heater is powered by external electricity, not your car battery. This means you can leave it plugged in overnight without draining your battery. The heating element warms the engine block and coolant, keeping everything at an optimal temperature for starting.

2. How to Use the Block Heater

Using the block heater is straightforward, but following the correct steps is crucial:

1

Park Near an Electrical Outlet

Drive your car close enough to an electrical outlet so the block heater cable can reach. Make sure there's enough space to access both the cable and the outlet.

2

Locate the Block Heater Cable

Find the block heater cable at the front of your car. It should have a plug that's accessible from the engine bay area or grille.

3

Connect the Cable to the Outlet

Grab the cable plug and connect it to the electrical socket. The heater will start working immediately.

4

Turn Off the Engine

The block heater works while the engine is OFF. You can leave it plugged in while you sleep or do other activities in the game.

5

Unplug BEFORE Driving!

CRITICAL: Always disconnect the cable before trying to start or drive your car. Forgetting this step will cause problems!

6

Start Your Car

With the cable disconnected, turn the ignition. The preheated engine should start almost immediately, even in extreme cold!

✅ Quick Summary

Park → Connect cable → Wait → Disconnect → Start! It's that simple, but don't forget step 5!

3. Benefits of Preheating

Using the block heater provides several key advantages:

🚗

Instant Cold Starts

Engine starts immediately without struggling or cranking.

🔥

Faster Cabin Heat

Car heater works better when engine is pre-warmed.

🛡️

Engine Protection

Reduces cold-start wear on engine components.

Time Saving

No waiting for engine to warm up before driving.

🌡️ Cold Start Problems Without Preheating

In extreme cold, your engine oil becomes thick and sluggish. Without preheating, your car may:

  • Struggle to start or fail to start entirely
  • Take a long time to warm up
  • Have weak cabin heating initially
  • Experience increased engine wear

4. Important Warnings

🚨 NEVER Forget to Unplug!

You MUST disconnect the block heater cable before attempting to drive. If you forget:

  • Your car will not start or move correctly
  • You may damage the cable or outlet
  • The cable could get tangled or ripped off

✅ Pre-Drive Checklist

☑️ Block heater cable is UNPLUGGED
☑️ Cable is stowed properly (not dragging)
☑️ Engine starts smoothly
☑️ Good to drive!
❌ Common Mistakes
  • Forgetting to unplug before driving
  • Parking too far from the outlet
  • Not allowing enough time for the engine to warm

5. Power Outlet Locations

You'll find electrical outlets at various locations around the game world. Common spots include:

Location Notes
Your Apartment Parking area near apartment block
Parents' House Garage or exterior
Fleetari's Garage Workshop area
Various Buildings Look for outlets on building exteriors
💡 Finnish Reality

In real-life Finland, block heater outlets are extremely common! Many parking lots, especially at apartment buildings and workplaces, have dedicated posts with electrical outlets for car heaters. This is a necessity in a country where winter temperatures can drop to -30°C or lower!

6. Pro Tips

💡 Best Practices
  • Plug in before sleeping: Let the heater work while you rest
  • Park strategically: Always consider outlet access when parking
  • Make unplugging a habit: Always check before starting the engine
  • Combine with other warmth: Use car heater for cabin warmth after starting

Real-World Context

In real Finnish winters, block heaters are typically used when temperatures drop below -15°C (5°F). About 3-4 hours of preheating is usually sufficient to warm the engine adequately.

Scenario Recommendation
Overnight parking Plug in before bed, unplug in morning
Short stop Engine may still be warm, check if needed
Extreme cold (-30°C+) Always use the block heater
