✅ Tire condition & pressure verification

🌡️ Summer heat is coming. Is your fleet ready?

Rising temperatures put serious stress on cooling systems, AC units, and engine components. A small coolant leak or a failing compressor in June can mean a breakdown in July, right when you can least afford it.

Get ahead of it now.

✅ AC system performance test
✅ Coolant flush & concentration check
✅ Radiator & hose inspection
✅ Compressor & refrigerant check

Schedule your summer fleet prep before the heat hits.
