The recommended maintenance schedule for the Peterbilt Model 535 includes regular oil and filter changes every 15,000 miles, tire rotation every 30,000 miles, and a comprehensive inspection every 60,000 miles. Always refer to the owner's manual for detailed intervals and procedures.
To troubleshoot electrical issues, start by checking the battery connections and fuses. Use a multimeter to test for power at various points and inspect wiring for any visible damage. For complex issues, consult a professional technician.
The correct tire pressure for the Peterbilt Model 535 typically ranges from 90 to 110 psi, depending on load and tire specifications. Always refer to the tire manufacturer's recommendations and the truck's placard for precise values.
To reset the maintenance light, turn the ignition key to the "on" position without starting the engine. Press and hold the trip reset button until the maintenance light blinks and turns off. Release the button to complete the reset.
Common causes of engine overheating include low coolant levels, a malfunctioning thermostat, a clogged radiator, or a failing water pump. Regular maintenance and inspections can help prevent overheating issues.
To improve fuel efficiency, maintain proper tire pressure, ensure regular engine tune-ups, minimize idling, and drive at consistent speeds. Aerodynamic accessories and reducing excess weight can also contribute to better fuel economy.
If the transmission is slipping, check the transmission fluid level and condition. Low or contaminated fluid can cause slipping. If the issue persists, have the transmission inspected by a qualified technician for potential mechanical problems.
To adjust the brakes, ensure the vehicle is on a level surface and safely chocked. Use a brake adjustment tool to turn the adjuster screw until the brake shoes are snug against the drum, then back off slightly for free wheel rotation. Follow specific guidelines in the service manual.
Signs of a failing alternator include dimming headlights, a dead battery, electrical component malfunctions, or a battery warning light on the dashboard. If these symptoms occur, have the alternator tested and replaced if necessary.
To check for air leaks, perform a visual inspection of hoses and fittings for wear or damage. Apply soapy water to suspected leak areas and watch for bubbles. Listen for hissing sounds which indicate leaks, and repair any identified issues promptly.
