December 28, 2025Car Maintenance in Winter | Tips and Tricks from Biswas Automobiles
Driving during the cooler months in Dhaka might not mean snow or ice, but winter still brings unique challenges to your vehicle. At Biswas Automobiles, we’ve spent years servicing cars across Dhaka—from Uttara to Dhanmondi, Mirpur to Banani—and we’ve seen what local winter conditions can do to your engine, battery, and even paintwork.
Moisture in the air, foggy mornings, sticky dew, and cooler night temperatures cause wear in ways most drivers overlook. That’s why winter car maintenance isn’t just good practice—it’s necessary to keep your car reliable, safe, and protected.
Whether you drive a hybrid, electric, family sedan, SUV, or light truck—we’re here to help you prepare for Dhaka’s version of winter with this complete maintenance guide.
Why You Must Maintain Your Car in Dhaka Winters
We don’t experience freezing temperatures or snowfall, but Dhaka’s winter comes with moisture-heavy air, fog buildup, low sunlight, and more traffic. Combined, these conditions put hidden stress on your car.
Common winter problems we fix at our service center:
- Battery failures in the morning
- Moisture fogging up inside headlights
- Slippery tires from cold air pressure drops
- Rust buildup under the car and door panels
- Dirty windshields reducing visibility
- Harder engine starts and sluggish pickup
Most of these issues can be prevented with simple, regular care. We’ll explain exactly what to do, how often, and what to watch for.

Full Winter Car Maintenance Checklist
1. Battery Health Check
Low temperatures weaken battery performance. If your car struggles to start in the morning, the battery may be on its last legs.
We check:
- Battery voltage and reserve capacity
- Cracks, corrosion, or loose terminals
- Charging and alternator performance
- Battery fluid level (where applicable)
- EV/hybrid high-voltage battery diagnostics
We recommend battery replacement every 3–4 years, especially before winter begins.
2. Tire Pressure and Tread Inspection
When the weather cools, tire pressure drops. This affects your grip and braking response—especially dangerous during early morning drives on damp roads.
Our winter tire care includes:
- Digital pressure reading and inflation
- Sidewall and tread wear inspection
- Rotation if needed (for even wear)
- Alignment check if the car pulls to one side
Optimal PSI for most sedans is 30–35 PSI. We always check your vehicle specs.
3. Windshield, Wipers & Washer System
Fog and dew cause low visibility. Bad wipers or empty washer fluid can make things worse.
We inspect and replace:
- Wiper blades (cracked or streaky ones)
- Washer nozzles for clogs
- Fill with anti-fog washer fluid
- Apply anti-mist interior glass treatment
Replace wipers every 6 months—most drivers forget this.
4. Headlights and Fog Lights
Shorter days mean more night driving. Fogged or weak headlights are a safety hazard.
What we check:
- Lens cleaning and polishing (if hazy)
- Beam alignment (aimed too low or too high)
- Fog light brightness
- Full electrical circuit health
We also offer headlight restoration without replacing the unit.
5. Engine Oil and Air Filter
In cooler temperatures, oil becomes thicker, and dirty filters can reduce fuel efficiency.
What we do:
- Check oil level and condition
- Replace with winter-grade oil (as per specs)
- Change air filter and cabin filter
- Throttle body cleaning (optional)
Always stick to manufacturer-recommended viscosity for winter.
6. Brake Pads and Brake Fluid
Moisture in brake fluid can reduce braking performance. Winter driving requires responsive brakes.
We inspect:
- Brake pad wear
- Brake fluid condition (DOT3/4)
- Caliper function and noise
- Rotor condition
Brake fluid should be flushed every 24 months or if it’s over 3% moisture level.
7. Coolant and Heater System Check
Your heater relies on your coolant system. Even if you rarely use the heater, bad coolant can damage your engine.
Our service includes:
- Coolant level and antifreeze ratio check
- Radiator pressure test
- Heater and defogger performance
- Cabin heating vents inspection
Never open a hot radiator cap—let us inspect it safely.
8. Rust Protection and Exterior Cleaning
Winter fog and moisture stick to the underbody and door panels. If ignored, this causes rust.
We offer:
- Underbody wash and anti-rust coating
- Nano wax polish for water resistance
- Clay bar treatment to remove winter grime
- Door seal inspection
A clean car also reduces chances of sensor malfunction in modern vehicles.
