How Salt and Cold Weather Affect Your Car’s Undercarriage

Alternative Automotive • February 3, 2025

Winter roads may be necessary for safety, but the salt and cold weather can wreak havoc on your car’s undercarriage.

Salt, while great for melting ice, is highly corrosive and can lead to rust and damage to critical components under your vehicle.

What Gets Damaged?

Frame and Suspension: Salt and moisture can corrode metal, weakening your car’s structure and suspension components.
Brakes: Corrosion can affect brake lines, reducing their effectiveness and increasing the risk of failure.
Fuel and Transmission Lines: Rust can develop on these lines, leading to leaks or costly repairs.

How to Protect Your Undercarriage

• Wash Regularly: Rinse the undercarriage frequently during winter to remove salt buildup.
• Apply Undercoating: A professional undercoating can provide a protective barrier against salt andmoisture.
• Schedule Inspections: Routine inspections can catch early signs of corrosion before they become major issues.
