Spring is a time for renewal, as the roads finally clear of ice and snow and the urge to head out on longer trips returns. However, winter is rarely kind to your vehicle. Salt, grit, rapid temperature fluctuations, and the potholes that emerge with the thaw all take a heavy toll on your car’s core components. To ensure your spring journey doesn’t end on the shoulder of the road, the experts at RS Pro Auto have compiled a comprehensive guide to the seven most critical checks to perform before you set off.
1. Fluid Level and Quality Control
During winter, your engine and its support systems work under increased strain. Your first task is to pop the bonnet and perform a detailed inspection. Check the engine oil level and condition. If the oil has turned jet-black or shows signs of emulsion (white foam), it could indicate condensation or a coolant leak into the engine.
Coolant: Ensure the level in the expansion tank is between the ‘MIN’ and ‘MAX’ marks. After winter, micro-cracks often appear in rubber hoses, leading to slow coolant evaporation. Don’t forget the brake fluid—it is hygroscopic, meaning it absorbs moisture. If it hasn’t been changed in the last two years, its boiling point may be dangerously low, which is a major risk during long descents or heavy braking.
2. In-depth Brake System Inspection
Your brakes are your primary safety guarantee. Road salt often causes brake caliper guide pins to seize and triggers corrosion on brake disc surfaces. Check your brake pad thickness—if it is less than 3-4 millimetres, they must be replaced immediately. Uneven pad wear is a clear indicator that a caliper is not functioning correctly.
Pay close attention to brake hoses. If you notice cracks or ‘bubbles’ on them, there is a high risk they could burst during emergency braking. Remember that brake efficiency in spring is critical, as asphalt surfaces can range from warm to unexpectedly icy during early morning hours.
3. Suspension and Steering Linkage
Latvian roads in spring are a true test for your chassis. Potholes hidden under puddles can damage your suspension in a single trip. Put the car on a lift and inspect:
- Control Arm Bushings: Check for rubber components that are cracked or detached from the metal sleeves.
- Tie Rod Ends and Links: Any play (looseness) will affect vehicle handling and cause uneven tire wear.
- Shock Absorbers: Look for signs of oil leaks. A leaking shock absorber cannot maintain tire contact with the road, significantly increasing your stopping distance.
4. Battery and Charging Voltage
Many drivers mistakenly believe that a battery only ‘dies’ in winter. In reality, the heat and higher electrical loads of spring and summer often finish the job winter started. Check the battery terminals—if they are oxidized (white or bluish crust), clean them and apply a specialized terminal grease.
Use a multimeter to measure the charging voltage while the engine is running. It should be between 13.8V and 14.4V. If the voltage is lower, the alternator cannot properly charge the battery, and at some point, the car simply won’t start. If it is higher, you risk ‘cooking’ the battery and damaging the car’s sensitive electronics.
5. Tire Condition and Pressure
Transitioning from winter to summer tires is the perfect time for an in-depth inspection. Check the tread depth—the legal minimum for summer tires is 1.6 mm, but for safe driving in rain, we recommend at least 3 mm. Pay attention to the age of the tires (DOT code)—if they are older than 5-6 years, the rubber loses its elasticity and hardens.
If you notice uneven wear, it is a sign of poor wheel alignment. If you feel steering vibration during your spring trip or notice a flat tire, remember that a modern mobile tire service can resolve the issue right at the roadside. Costs for such a service generally start from 40 EUR—a small price for comfort and saved time.
6. Lighting and Visibility
Spring downpours and dusk demand perfect visibility. Check all bulbs: low/high beams, turn signals, and, most importantly, brake lights. During winter, salt often corrodes electrical contacts, causing lights to flicker or fail completely.
Replace your wiper blades. Ice and snow usually damage the rubber edge over winter, causing streaks across the windscreen that worsen visibility in sun glare. Also, ensure your washer jets are aimed correctly and are not blocked.
7. Underbody Cleaning and Protection
Last but not least—get rid of the ‘winter legacy.’ Salt accumulated on suspension components, brake lines, and the undercarriage continues to corrode long into spring, as moisture and warmth accelerate the rusting process. A professional car wash with an underbody spray function is a mandatory step before the season begins.
Also, check your car’s drainage channels (under the windscreen and sunroof area). If they are full of last year’s leaves and mud, spring rainwater can leak into the cabin or damage expensive electronic control units.
