Cost Savings

Checklist Tasks

• Inspect timing belt or chain for cracks or slack to prevent engine failure.
• Check valve cover and oil pan for leaks that could lower oil pressure.
• Test alternator output under load to identify weak charging systems.
• Examine CV boots for tears or grease to prevent axle damage.
• Flush transmission fluid and replace filter to prevent shifting problems.
• Measure brake rotor thickness and check for hot spots to avoid rotor warping.
• Inspect radiator and heater hoses for soft spots or swelling to avoid bursting.
• Check wheel bearings for play by rocking wheels to spot early wear.
• Clean mass airflow sensor with proper spray to restore fuel efficiency.
• Test door and trunk seals with a dollar bill to identify water leaks.
• Scan for inactive engine codes to find hidden sensor or emissions issues.
