Winterize Your Fleet for Chicago’s Harsh Seasons

Team #312Truck
Prepare your Chicago truck fleet for winter with 312 Truck Body Repair & Painting’s expert maintenance - anti-gel fuel treatment, corrosion protection, tire checks, and a full winterization service.
Chicago Winters Are No Joke – 312 Truck Has You Covered
From freezing wind chills to salt-covered highways, Chicago’s winter can do serious damage to your trucks. At 312 Truck Body Repair & Painting, we specialize in keeping semi-trucks and commercial fleets running strong all season long.
Our team understands how local weather affects your vehicles, and we have the experience, tools, and technology to keep your trucks safe, corrosion-free, and performing at their best.
Full-Service Engine & Cooling System Winterization
Your engine works harder in the cold. Our truck body shop technicians check every component so you don’t face costly breakdowns later.
We handle:
- Coolant and antifreeze testing for sub-zero protection.
- Hose, belt, and clamp inspections to prevent cracking or leaks.
- Block heater installation and engine pre-heating systems for easy starts.
When temperatures drop, you can trust 312 Truck Body Repair & Painting to keep every semi-truck in your fleet running smoothly.
Battery & Electrical System Checks
Don’t get stranded with a dead battery this winter. Our certified team performs:
- Battery load testing and terminal cleaning.
- Alternator and starter checks.
- Full lighting inspections – critical for dark, icy roads.
We make sure your electrical systems stay reliable through every storm.
Fuel, Oil & Fluid System Protection
Cold weather and diesel don’t always mix. That’s why 312 Truck Body Repair & Painting uses top-tier winter maintenance solutions to protect your fleet:
- Anti-gel diesel additives and winter-grade fuel treatments.
- Cold-rated oil and washer fluids for Chicago’s extreme temperatures.
- Fuel filter and water separator service to prevent frozen lines.
Your semi-trucks will start reliably, idle smoothly, and stay efficient all winter long.
Tires, Brakes & Traction Checks
Safety starts where the rubber meets the road. Our team inspects every tire, brake, and traction system to ensure your fleet can handle ice, slush, and sudden stops.
We’ll:
- Check tread depth and adjust pressure (cold weather reduces PSI).
- Inspect brakes for moisture buildup and wear.
- Recommend snow-rated tires or chains for high-risk routes.
With 312 Truck Body Repair & Painting, you can trust your drivers are ready for anything.
Rust, Salt & Body Protection
Chicago’s road salt is brutal, but our truck body shop can stop corrosion before it starts. We provide:
- Undercarriage cleaning and rustproof coatings.
- Frame and panel protection against salt corrosion.
- Body repair and refinishing for existing rust or damage.
If your semi-trucks already show signs of wear, we can restore and protect them for the long haul.


Winter Fleet Maintenance Plans
Winterization isn’t a one-time job. Our team builds custom maintenance plans to keep your trucks safe all season long:
- Pre-winter inspections: Comprehensive checks before temperatures drop.
- Mid-winter service: Battery, brake, and tire rechecks.
- Post-storm cleanup: Salt removal and corrosion protection.
