2018 International MV Maintenance Schedule: Your Comprehensive Guide
The 2018 International MV series is a workhorse designed for demanding medium-duty applications. Whether you're in last-mile delivery, construction, or municipal services, keeping your MV properly maintained is crucial for minimizing downtime and maximizing its service life. This guide will provide a detailed maintenance schedule, highlight common issues, discuss severe-duty adjustments, and give you an idea of typical service costs.
Factory Service Intervals
International provides specific service intervals to ensure optimum performance and reliability. These intervals are based on mileage or operating hours, whichever comes first. Always refer to your owner's manual for the most accurate and up-to-date information, as variations can occur based on specific configurations and engine choices (Cummins B6.7 or L9).
| Service Item | Interval (Miles/Hours) | Notes |
|---|---|---|
| Engine Oil & Filter | 15,000 miles / 500 hours | Or annually. Use API CJ-4 or CK-4 rated oil, typically 10W-30 or 15W-40. |
| Fuel Filters | 30,000 miles / 1,000 hours | Primary and secondary filters. More often with poor fuel quality. |
| Air Filter | As needed / Annually | Inspect regularly, replace when restricted or dirty. |
| Coolant | 60,000 miles / 2,000 hours | Or every 2-3 years. Use extended life coolant (ELC) only. |
| Transmission Fluid | 50,000-100,000 miles | Varies by transmission (Allison automatic, Eaton manual). Consult manual. |
| Differential Fluid | 100,000 miles / 3,000 hours | Or every 3-5 years. |
| Power Steering Fluid | 100,000 miles / 3,000 hours | Inspect levels regularly. |
| Brake System | Inspect annually | Air dryer filter annually, inspect lines, chambers, and pads regularly. |
| Serpentine Belt | 150,000 miles / 4,500 hours | Inspect for cracks and wear at every service. |
| Spark Plugs | N/A | Diesel engine, no spark plugs. |
| DEF Filter | 100,000 miles | Replace at specified intervals. |
Known Issues and Common Problems (2018 International MV Generation)
The International MV series, while robust, can experience certain issues typical of its generation and class. Being aware of these can help with proactive maintenance and quicker diagnosis:
- DEF System Malfunctions: Diesel Exhaust Fluid (DEF) system issues are relatively common across many modern diesel trucks. This can include sensor failures, crystallization in the lines, or DPF (Diesel Particulate Filter) regeneration problems, leading to reduced engine power (derate).
- Electrical Gremlins: Modern trucks are laden with complex electronics. Intermittent electrical issues, sensor failures, or wiring harness problems can occur, leading to dash warning lights or operational hiccups.
- Air System Leaks: Given the extensive air brake and accessory air systems, small leaks can develop over time, leading to air pressure loss. Regular inspection of air lines and fittings is crucial.
- HVAC System Issues: Reports of HVAC blower motor failures or issues with the blend door actuators are not unheard of.
- Exhaust System Cracks/Leaks: Due to high heat and vibrations, exhaust manifold gaskets or even the manifolds themselves can develop cracks over time, leading to exhaust leaks and potential performance issues.
