A commercial truck works harder than a passenger car. More load, more miles, more stop-and-go in Memphis summer heat. The result: components wear faster, and deferred maintenance accelerates that wear exponentially. This checklist is built for owner-operators and small fleet managers who want to keep their vehicles running without surprise breakdowns.
Every 5,000–7,500 Miles
- →Oil and filter change — synthetic oil extends intervals; use manufacturer-specified oil weight for your engine
- →Tire pressure check — proper inflation improves fuel economy and prevents premature wear; commercial vans run higher PSI than passenger vehicles
- →Inspect tires for wear, cracks, and punctures — commercial vehicles carry more load, which accelerates sidewall stress
- →Check all fluid levels: coolant, brake, power steering, transmission, windshield washer
- →Test all lights: headlights, brake lights, turn signals, reverse lights
- →Inspect wiper blades and replace if streaking
Every 15,000–20,000 Miles
- →Rotate tires — cargo vans and box trucks put uneven wear on rear tires under load
- →Inspect brake pads and rotors — commercial use wears brakes faster than passenger use; inspect front and rear
- →Check and clean battery terminals
- →Inspect belts and hoses for cracking, fraying, or swelling
- →Inspect air filter — Memphis summer construction season means more dust and debris
- →Lubricate door hinges, sliding door rollers (cargo vans), and lift gates if equipped
Every 30,000 Miles
- →Transmission fluid change — especially important for cargo vans and box trucks that do high stop-and-go mileage
- →Coolant flush — Memphis summers are hard on cooling systems; flush and refill with fresh coolant
- →Inspect and clean throttle body
- →Inspect suspension components: tie rods, ball joints, CV axles — loaded commercial vehicles stress these more than passenger cars
- →Replace cabin air filter
- →Inspect and repack wheel bearings if high mileage
Every 60,000–100,000 Miles
- →Replace spark plugs (gas engines) — extended life plugs typically go 100,000 miles but check condition
- →Replace timing belt if applicable (check your specific engine — interference engines must not skip this)
- →Inspect and possibly replace brake rotors if under minimum thickness
- →Differential fluid change (rear-wheel drive trucks)
- →Transfer case fluid change (4WD trucks)
- →Inspect exhaust system for leaks, rust, and loose hangers
Seasonal: Before Memphis Summers
- →AC system: check refrigerant charge and inspect for leaks; Memphis July with no AC in a cargo van is brutal
- →Cooling system: verify thermostat function and coolant concentration
- →Battery: test cold cranking amps — heat kills batteries faster than cold
- →Tire pressure: re-check as temps rise (pressure increases ~1 PSI per 10°F rise)
Why This Matters for Resale
A commercial truck with documented maintenance history — even just oil change receipts and notes in a logbook — is worth significantly more on resale than one without records. Buyers, dealers, and commercial lenders all place a premium on verifiable maintenance. Keep a simple folder in the vehicle with every service receipt.
