Built FOR THE DEMANDS OF YOUR BUSINESS

International trucks serve a wide range of commercial applications. Their maintenance needs vary by model, engine, age, and workload, making attention to your truck’s specific configuration essential.


Frequent stops, extended idling, heavy loads, and daily mileage can all influence maintenance requirements. Keeping track of these demands helps you plan service around the way your truck actually works.


At American Auto Service, we take a practical approach to diesel care. We listen to your concerns, review your vehicle’s maintenance history, and help you prioritize the work needed to keep it dependable.

Address performance problems early

A change in your truck’s performance can be the first sign that something needs attention. Hard starting, rough idling, excessive exhaust smoke, overheating, or reduced pulling power should be evaluated before they lead to more downtime.


Warning lights and recurring fluid leaks also deserve prompt attention. Scheduling an inspection when symptoms first appear gives you a clearer understanding of the problem and helps you make informed repair decisions.

Maintenance for Your INternational Diesel Engine

A consistent maintenance plan helps you stay ahead of wear and identify developing problems. Follow the service recommendations for your specific truck and engine, with adjustments for operating conditions where the manufacturer requires them.


OIL & FILTER SERVICE

Use the recommended engine oil and replace the oil filter at the appropriate interval. Routine oil service supports proper lubrication and provides an opportunity to check for leaks or unusual consumption.


Fuel system Maintenance

Replace fuel filters as recommended and inspect the fuel system for leaks or contamination. Give hard starting, hesitation, and uneven engine operation prompt attention.


COOLING SYSTEM INSPECTIONS

Check coolant condition and inspect hoses, belts, radiator components, and connections. Address coolant loss or rising operating temperatures before continuing to put the engine under load.

 

Air Intake & Turbocharger Inspections

Inspect the air filter, intake connections, and charge-air piping. Restricted airflow or leaks can affect engine performance and should be evaluated when power or efficiency changes.


Starting & charging system checks

Reliable starting depends on healthy batteries, sound connections, and a properly functioning charging system. Have slow cranking or intermittent starting problems checked before they interrupt your workday.


ROUTINE VEHICLE CHECKS

Diesel engine care works alongside regular inspections of the brakes, tires, steering, suspension, and drivetrain. Keeping the entire vehicle maintained helps support dependable operation.
