As winter settles in, car owners are preparing their vehicles for the colder months ahead. While many workshops remember the basics of a winter car maintenance check, like tire changes and checking antifreeze levels, there’s one critical component that often goes unnoticed: the air suspension system. Neglecting this during a routine winter vehicle inspection can lead to costly repairs and unsafe driving conditions. Here’s why workshops should include an air suspension check in every winter car maintenance checklist.
Why Air Suspension Checks Are Critical for a Complete Winter Car Maintenance Check
Winter brings freezing temperatures, icy roads, and heavy snow—conditions that put significant strain on vehicle systems, especially air suspension. Components like air springs, compressors, and valves are particularly vulnerable to winter vehicle damage and can deteriorate faster when exposed to extreme temperatures.
By making air suspension inspections a part of your winter car maintenance check, you not only ensure your customers’ vehicles are safe and reliable but also demonstrate thoroughness and professionalism that builds trust and loyalty in your workshop.
How to Perform an Air Suspension Check for Winter Car Maintenance
When performing a tire change during your winter car maintenance check, the vehicle’s wheels are already off, making it the perfect opportunity to inspect the air suspension system for winter-specific issues and prevent winter breakdowns. Here’s a step-by-step guide to performing an effective winter suspension check:
- Start with the Customer Conversation
A simple conversation can uncover potential air suspension issues. Ask your customer:
- “Have you noticed your car sagging more than 2.5 cm overnight?”
- “Does one corner of the vehicle appear lower than the rest?”
If the customer mentions either issue, a deeper inspection is necessary.
- Visual Inspection of Air Springs and Struts
Look for small cracks or signs of wear on the rubber components of air springs. Cold weather makes rubber harder and less flexible, increasing the likelihood of suspension failure. Explain to customers that addressing small issues now can prevent a winter breakdown during freezing temperatures.
- Check for Leaks
- Spray the air springs and connectors with a soap-and-water solution. If you see bubbles, it indicates a leak. Some leaks may occur in less visible areas, like the folding edge of the air spring, which is not visible at normal ride height, so be thorough.
- Check the air struts and shock absorbers for oil leakage and excessive rust.
- Inspect the Compressor and Air Hoses
Ensure the compressor is functioning properly and inspect the air inlet hose for cracks. A damaged hose can introduce dirt and moisture into the system, which can cause oxidation and problems in the valve block when it freezes. This will prevent the vehicle from leveling and trigger a fault code on the instrument cluster.
Tips for a Safe Air Suspension Inspection
- Use “Jack Mode” If Available: Check if the vehicle features a special “jack mode.” If present, use it to prevent the air being extracted from the bellow when jacking up the car. If this mode is not present, the car can be jacked without any precautionary measure. Some systems even automatically recognize that the car is being raised and retain the desired amount of pressure in the air springs.
- Avoid Depressurizing the System: Never lower the car with a depressurized air suspension system. This can cause improper unfolding of the air bellows, leading to system failure or damage to the crimp ring.
Don’t Forget the Basics
While air suspension checks are essential, make sure the rest of the winter car maintenance checklist is covered, including:
- Installing winter tires with proper tread depth.
- Testing the battery and alternator for cold-weather reliability.
- Inspecting brake pads, rotors, and fluid levels.
- Ensuring wipers and washer fluid are winter-ready.
Build Trust with Expert Service
Adding an air suspension inspection to your winter car maintenance check helps prevent costly winter breakdowns and repairs. By catching issues like leaks or worn air springs early, you can avoid expensive fixes like compressor replacement. This proactive service keeps your customers’ vehicles running smoothly, enhances their trust in your workshop, and ensures comfort and performance during winter conditions. Offering thorough checks also opens the door to additional services and boosts customer loyalty, helping your workshop stand out as a reliable, preventative care provider.
