Spring Car Maintenance — Complete Checklist 2026
Latvian winter is harsh on cars — salt, potholes, cold, and moisture leave their mark. Spring is the time to assess damage and prepare your car for summer. This guide covers everything needed — from tire changes to body protection.
1. Tire Change and Inspection
Tire change is the first and most important spring task.
Timing
In Latvia, winter tires are mandatory until April 1st (allowed until May 1st). Switch when average daily temperature consistently exceeds +7°C. Usually late March – early April.
Summer tire inspection
Before mounting, check: tread depth (minimum 1.6mm, recommended ≥3mm), age (max 6-8 years), sidewall cracks, even wear. Uneven wear indicates wheel alignment issues.
Wheel alignment
After winter potholes, recommended to check alignment (€20-40). Extends tire life and improves handling. Signs: car pulls to one side, steering vibrates.
Rim inspection
Potholes can deform rims. Check visually — deformed rims cause vibration and can damage tires. Aluminum rim repair: €30-60 per rim.
2. Body Inspection and Protection
Salt and moisture are the main causes of corrosion. Spring is the time to assess condition.
Thorough wash
Start with a careful wash including underbody and wheel arches. Road salt accumulates in these areas and continues corroding metal. Use a car wash with high-pressure underbody cleaning.
Corrosion inspection
After washing, check: sills, door bottoms, wheel arches, trunk lid edges, brake lines. Rust often starts as dots — look for bubbles under paint too.
Scratch treatment
Treat winter scratches with primer and paint before they start rusting. Small scratches: touch-up pen (€10-20). Larger: service (€50-200).
Wax and protective coating
After washing, apply wax or ceramic coating. Protects paint from summer UV and eases future cleaning. Investment of €30-80 saves hundreds in repairs.
Underbody anti-corrosion treatment
If the car is older than 5 years — consider professional underbody treatment (€100-300). Latvian road salt is aggressive, and treatment every 2-3 years can extend car life by 5+ years.
3. Fluid Check and Replacement
Winter wears out fluids faster. Check all of them in spring.
Engine oil
Check level and color. If oil is black and thick — time to change. Winter driving (short trips, cold starts) wears oil faster. Change: €40-80 with filter.
Brake fluid
Change every 2 years regardless of mileage. Brake fluid absorbs moisture, lowering boiling point. Change: €30-60. Critical for safety!
Coolant
Check level and concentration. If you added water in winter — concentration may be too low for summer (corrosion risk). Full change: €30-50.
Windshield washer fluid
Replace winter fluid (with anti-freeze) with summer variant. Summer fluid better cleans insects and dust. €3-5 per 5L.
Power steering fluid
Check level. If dropped — possible leak. Insufficient level can damage the pump (repair: €200-500).
4. Brake System Inspection
Winter salt and moisture accelerate brake wear. Always check after winter.
- 🔧Brake pads: check thickness. Minimum: 3mm (recommended to change at 4mm). Uneven wear indicates caliper problems.
- 🔧Brake discs: check grooving and thickness. Winter salt and moisture accelerate corrosion. Rust ring on disc edge is normal, but grooves and surface corrosion are not.
- 🔧Brake lines: visually inspect — rust and corrosion can lead to bursting. If lines are corroded — replace immediately (safety!).
- 🔧Handbrake: check if it holds the car on a slope. After winter, the cable may have stretched. Adjustment: €10-20.
- 🔧Test drive: listen for squeaking, squealing, or vibration when braking. Any unusual noise = visit service.
5. Electrical System and Lighting
In winter, the battery and lighting suffer the most.
Battery
Check voltage (≥12.4V is good). If you had starting problems in winter — consider replacement. Average battery life: 4-6 years. New: €80-150.
Lighting
Check ALL bulbs: low/high beam, indicators, brake, reverse, fog lights. Burnt bulbs = fine at inspection and danger. Replacement: €5-30 per bulb.
Wiper blades
Winter wears blades quickly. If they streak or make noise — replace. Good blades: €15-40 per pair. Saves nerves and improves visibility.
Air conditioning
Turn on and check — does cold air come quickly and evenly? If not — may need recharge (€40-80) or filter change (€20-40). Better to check in spring than suffer in summer.
6. Suspension and Chassis
Latvian potholes are suspension's main enemy. Assess the damage in spring.
- ⚙️Shock absorbers: if the car "sways" or "bounces" over small bumps — shocks may be worn. Visual check: oil traces = immediate replacement.
- ⚙️Tie rod ends and bushings: knocking when driving over uneven road = worn parts. Platform inspection: €20-30.
- ⚙️Wheel bearings: humming noise that changes with speed = bearing problem. If ignored — bearing can collapse while driving.
- ⚙️Visual inspection: check rubber boots on tie rod ends and joints. Cracked boots = dirt inside = rapid wear.
7. Interior Care After Winter
In winter, moisture, salt, and dirt accumulate inside. Spring cleaning isn't just aesthetics.
- 🧹Floor mats: remove, wash, and dry. Moisture underneath can cause corrosion and mold.
- 🧹Cabin air filter: change every 15,000-20,000 km or once a year. Clogged filter = poor cabin air and weaker AC. Change: €15-40.
- 🧹Rubber seals: treat with silicone. Winter makes them stiff and brittle. Treatment extends life and prevents water ingress.
- 🧹Plastic and leather care: use specialized products. Winter sun + heating dries materials. Prevention is cheaper than replacement.
- 🧹Moisture check: if windows fog up often — there's moisture inside. Check drainage openings, air filters, and seals. Prolonged moisture = mold and health risks.

Frequently Asked Questions
When should I switch from winter to summer tires?
In Latvia, winter tires are mandatory until April 1st. Recommended to switch when average daily temperature consistently exceeds +7°C (usually late March – early April). Switching too early on icy roads is dangerous.
How much does full spring car maintenance cost?
Basic maintenance (oil change, filters, fluids): €100-200. Tire swap: €20-40. Anti-corrosion body treatment: €50-150. Interior chemical cleaning: €50-100. Total: €220-490 depending on the car.
Should I do anti-corrosion treatment every spring?
Not mandatory every year, but recommended to inspect every spring. If you find rust starting — treat immediately. Preventive treatment every 2-3 years extends car life by years.
What fluids should I check in spring?
Engine oil (level and color), brake fluid (change every 2 years), coolant (level and concentration), power steering fluid, windshield washer fluid (switch from winter to summer).
How to spot hidden winter damage?
Check: rust spots under sills and wheel arch areas, pothole damage to rims, windshield chips, rubber seal condition, brake disc condition (grooving). On a test drive, listen for new noises.
Should I change engine oil in spring?
If you've driven 10,000-15,000 km or a year since the last change — yes. If not, a level check is enough. Winter driving (short trips, cold starts) wears oil faster.
