Truck Preventive Maintenance Quarterly Checklist

Truck Quarterly Preventive Maintenance Checklist is a structured inspection and service routine performed every three months to assess critical truck systems such as engine, brakes, transmission, suspension, and electrical components. This checklist includes fluid changes, filter replacements, safety system checks, and wear assessments to ensure compliance with DOT standards and prevent mechanical failures. Conducting quarterly PM enhances vehicle reliability, reduces costly breakdowns, and extends service life while supporting safe and efficient fleet operations.
