Maintaining Your Sigma Base:

Regular maintenance is crucial for preserving the longevity of your Sigma. Consider these components as part of your maintenance schedule:
• Engine: Parts such as the oil cap, thermostat housing gasket, distributor cap, and distributor pick up contribute to the engine's overall health. Monitoring and replacing these as needed can prevent larger issues.
• Drivetrain: The clutch kit (for manual transmissions), automatic transmission filter and filter kit, differential bearing assembly, and balance shaft chain guide upper all play vital roles in a smooth and reliable drivetrain. Inspect these components regularly.
• Steering & Suspension: A smooth ride and precise handling rely on parts like the bump stop (front) and regular power steering fluid checks.
• Other Components: Items such as the drive belt (alternator), valve stem seals, and wheel nuts (front) are crucial for overall vehicle operation and safety.

Addressing worn or faulty parts promptly can prevent further damage and maintain optimal performance.
