9 Winter Car Maintenance Tips 

Winter can be harsh on your car so be sure to take extra steps to ensure it runs smoothly and doesn’t leave you stranded in the cold. This winter car maintenance guide outlines some essential tips to prepare your car, from checking your battery and tyres to assembling some emergency kit in case you do come across some bad weather. 

• Regularly check and maintain your car battery, tyre tread depth, and coolant levels to prevent winter breakdowns.
• Use winter-specific screenwash and wiper blades to ensure clear visibility in adverse weather conditions.
• Prepare a comprehensive winter survival kit and carry essential gear to enhance safety during unexpected situations.

Check Your Car Battery

A flat or faulty car battery is a frequent cause of winter vehicle breakdowns. Cold, wet, and icy weather increases the likelihood of a dead battery, so testing your car battery’s voltage and replacing it if necessary is advisable. Check batteries older than three years before winter to prevent unexpected failures. If starting your car becomes difficult, it may be time to replace the battery before temperatures plummet.

Keeping battery terminals clean is crucial for maintaining performance. Corrosion and dirt can increase electrical resistance, particularly in cold weather. Remember to always carry an in-car phone charger and keep a fully charged mobile phone handy. If your car battery fails, you’ll have a way to call for help. 

Inspect Tyre Tread Depth

A decent tyre tread depth is vital for safe winter driving. While the legal minimum is 1.6mm, experts recommend at least 3mm for optimal safety on icy roads. Use a tyre tread depth gauge to measure accurately and replace if necessary. Properly inflated tyres with sufficient tread provide better traction and handling, reducing the risk of accidents in winter conditions.

Cold weather can cause tyre air pressure to drop, so regular checks are necessary. Properly inflated tyres ensure even wear and maintain optimal road contact. Inspecting your tyre tread depth can better prepare your car for winter driving challenges.

Top Up Screen Wash

Clear visibility is crucial for safe winter driving. Winter-specific screen wash prevents freezing and maintains clarity in snowy conditions. Unlike summer washer fluid, winter washer fluid includes a de-icer effective well past zero degrees. Premium screen wash may also offer water-repellency, enhancing visibility in rain and snow.

Heavily diluted screenwash or plain water can freeze and compromise visibility in winter. Always use winter-specific washer fluid and regularly top up your screen wash to avoid running out. 

Did you know? 

An empty washer bottle is not only unsafe, it is also illegal. Keep it filled and check frequently to be prepared for winter driving conditions.

Examine Wiper Blades

Functional wiper blades are vital for clear winter visibility. Inspect for tears, damage, or deterioration. Signs of wear include splits in the rubber or squeaking sounds. Damaged blades won’t clear your windshield effectively, posing a danger in wet weather and icy conditions.

Keep an ice scraper and de-icer on hand to remove ice and snow quickly, aiding your wiper blades. Regular examination and maintenance of wiper blades is a simple yet crucial part of winter car upkeep.

Check Coolant Levels

The engine’s cooling system is essential for smooth winter operation. Antifreeze prevents water in the engine’s cooling system from freezing. Before winter, ensure the correct amount of antifreeze is present. Replace coolant every 2-5 years to maintain effectiveness. Regularly checking and maintaining coolant levels prevents engine overheating and other issues in winter and is something included in a car service. 

Clean Battery Terminals

Cleaning battery terminals is often neglected but crucial for car maintenance. Corrosion buildup commonly causes starting issues, especially in cold weather.  After cleaning, apply a battery terminal protectant spray to reduce future corrosion. This simple task can significantly improve starting and charging performance, especially in winter. Clean battery terminals help prevent unexpected breakdowns and ensure your vehicle is winter-ready.

Always carry jump leads and a fully charged mobile phone in case of a dead battery. These essentials can help you get back on the road quickly and safely if you encounter battery issues. 

Lubricate Locks and Hinges

Cold weather can freeze car locks and hinges, making access difficult. Apply lubricant to door locks, latches, and hinges regularly. Spray lithium grease is effective, providing long-lasting lubrication and protection against freezing.

Prepare a Winter Survival Kit

It may seem extreme but if you plan on making long journeys, perhaps to see family near Christmas, prepare a winter survival kit for your car. Include items that ensure safety and comfort in emergencies. Start with an ice scraper and de-icer for clear visibility and legal compliance. 

Pack a fully charged mobile phone, a large torch with spare batteries, and warm clothing and blankets for comfort in case of a breakdown. A comprehensive winter survival kit ensures your car is ready for any situation during winter driving and winter weather. 

Check Lights and Indicators

Winter often means driving in dark conditions, so checking your car lights and indicators is crucial. Ensure all lights, including brake lights, tail lights, headlights, and indicators, work properly. Regularly verify their functionality by walking around your car or using reflections. Keep spare car bulbs in your vehicle for quick replacements.

Summary

By ticking off this winter car checklist, you can prepare your car to handle the harsh winter conditions. From checking your car battery to carrying essential winter gear, each step plays a vital role in maintaining your vehicle’s performance and safety.
