Winter: Freezing Temperatures and Road Salt

Winter in Illinois can be brutal, with freezing temperatures, ice, and road salt all affecting your car. Here’s what you need to watch out for:

  • Drained Battery: Cold weather can reduce your battery’s efficiency, making it harder to start your car.
  • Thickened Fluids: Engine oil and transmission fluid can thicken in freezing temperatures, affecting performance.
  • Tire Pressure Drops: Cold air causes tire pressure to decrease, leading to uneven wear and reduced traction.
  • Road Salt Damage: Salt is great for melting ice but can corrode your car’s undercarriage and body.

What to Do:

  • Have your battery tested and replace it if necessary.
  • Use winter-grade fluids to ensure proper performance.
  • Regularly check and adjust tire pressure.
  • Wash your car frequently to remove salt buildup and apply a protective undercoating.

Spring: Rain and Pothole Season

Spring brings heavy rains and the aftermath of winter road conditions—potholes. These elements can affect:

  • Brakes: Moisture can cause rust on brake components, reducing efficiency.
  • Suspension & Alignment: Potholes can damage your suspension, misalign your wheels, and lead to uneven tire wear.
  • Windshield Wipers: After a long winter, wipers may be cracked or ineffective.

What to Do:

  • Have your brakes inspected and replace worn-out pads or rotors.
  • Get a suspension and wheel alignment check.
  • Replace windshield wipers and check fluid levels.

Summer: Heat and Tire Stress

Summers in Illinois can be hot and humid, which can put stress on various parts of your car:

  • Overheating Engine: High temperatures can lead to engine overheating if coolant levels are low.
  • Tire Blowouts: Heat causes tire pressure to rise, increasing the risk of blowouts.
  • Battery Wear: Summer heat can shorten battery life just as much as winter cold.

What to Do:

  • Check and top off coolant levels regularly.
  • Inspect tires for signs of wear and adjust pressure accordingly.
  • Test your battery and replace it if needed.

Fall: Preparing for Cold Weather

Fall is the perfect time to prepare your car for the winter months ahead:

  • Cooling System Maintenance: Ensuring your radiator and coolant system are working properly prevents freezing issues.
  • Tire Check: Worn-out tires won’t provide enough traction on icy roads.
  • Lights & Visibility: Shorter days mean more night driving, making it crucial to have properly working lights.

What to Do:

  • Flush and refill your cooling system if needed.
  • Replace worn tires before winter hits.
  • Check all exterior lights and replace dim or burnt-out bulbs.
