Oldsmobile Cutlass 1998 Owner's Manual

The recommended oil type for a 1998 Oldsmobile Cutlass is 5W-30. Ensure you use high-quality motor oil that meets or exceeds API service classifications.
To reset the check engine light, use an OBD-II scanner to clear the error codes. If the light persists, consult a professional mechanic as there might be an underlying issue.
To change the air filter, locate the air filter housing in the engine bay, unclip or unscrew the cover, remove the old filter, and insert the new one. Ensure the filter is seated properly before closing the housing.
Overheating can be caused by several issues such as a faulty thermostat, low coolant levels, a damaged radiator, or a malfunctioning water pump. Inspect these components to diagnose the problem.
To replace the brake pads, lift the vehicle, remove the wheel, unbolt the caliper, remove the old brake pads, compress the caliper piston, and install the new pads. Reassemble in reverse order and ensure proper torque on all bolts.
Common causes include low transmission fluid levels, worn out transmission bands, or a malfunctioning torque converter. Regular maintenance and fluid checks can help prevent these issues.
Start by checking the battery and fuses. Use a multimeter to test for continuity and voltage at various points in the electrical system. Inspect wiring for signs of damage or corrosion.
Symptoms include difficulty starting the engine, engine sputtering, frequent stalling, and a noticeable decrease in fuel efficiency. A diagnostic test can confirm a fuel pump issue.
The 1998 Oldsmobile Cutlass typically uses a timing chain rather than a belt, which does not require regular replacement. However, it should be inspected periodically for wear.
Check the battery charge and connections, inspect the starter and alternator, and ensure there is fuel in the tank. If the issue persists, it may require diagnostic testing by a professional.
