This is what proactive fleet maintenance looks like in action. 🚛💪

A fleet customer came to us experiencing recurring downtime, trucks going out of service more than they should, repairs stacking up, and schedules getting harder to maintain.

We took a different approach.

Instead of just fixing what was broken, we built a proactive maintenance program for their operation, including scheduled inspections, early diagnostics, and a service plan tailored to their routes and workload.

The result:
✅ Fewer unexpected breakdowns
✅ More trucks on the road, on schedule
✅ Lower overall repair costs
✅ A fleet that runs the way it should

This is what it means to be more than a repair shop; it's what it means to be a fleet partner.

If your fleet is dealing with recurring downtime or reactive repairs, let's talk.

Colorado summers don't go easy on commercial vehicles. 🌡️

High temperatures put extra strain on cooling systems, batteries, tires, and engine components, and for fleet managers, that means a higher risk of unexpected breakdowns during your busiest season.

A few ways to keep your fleet performing in the heat:
🔧 Check coolant levels and test system pressure regularly
🔧 Inspect hoses and belts for heat-related wear and cracking
🔧 Test batteries, heat accelerates battery failure faster than cold
🔧 Monitor tire pressure daily, heat causes pressure fluctuations
🔧 Schedule AC system checks before temperatures peak
🔧 Watch for early signs of overheating, gauges, warning lights, steam

The best time to catch a heat-related issue is before it leaves your truck stranded on the side of the road.

Iron Buffalo keeps your fleet summer-ready with full-service inspections, cooling system repairs, and 24/7 mobile support when you need it most.
