The 1987 BMW 325i is a classic that has earned a reputation for its solid build and performance. If you’re considering owning one of these beauties, it’s essential to understand what makes it tick and how reliable it can be in the long run. This car is often praised for its engaging driving experience, but let’s dive deeper into the key components that contribute to its reliability.
Engine Performance
Power and Durability
The heart of the 325i is its M20 inline-six engine, which is known for its robustness. With a displacement of 2.5 liters, this engine delivers a smooth power band and can handle high mileage if properly maintained. Regular oil changes and attention to cooling systems are crucial. Neglecting these can lead to overheating or oil leaks, which are common issues in older models.
Common Issues
– Oil leaks from the valve cover gasket
– Cooling system failures, particularly with the water pump
– Timing belt wear, which should be replaced every 60,000 miles
Transmission Reliability
Manual vs. Automatic
The 325i comes with both manual and automatic transmission options. The manual transmission is generally more reliable and offers a more engaging driving experience. However, the automatic can also hold up well if serviced regularly.
Transmission Maintenance Tips
– Regular fluid changes are a must for both types.
– Watch for slipping or hard shifting, which can signal issues.
– Pay attention to the clutch in manual models; it should engage smoothly without grinding.
Suspension and Handling
Ride Quality and Longevity
The suspension system in the 325i is designed for a sporty yet comfortable ride. It features MacPherson struts in the front and a multi-link setup in the rear, providing excellent handling. However, age can take its toll on these components.
Key Suspension Components to Monitor
– Shock absorbers and struts should be inspected regularly for leaks.
– Bushings can wear out, leading to a harsher ride and less precise handling.
– Ball joints should be checked for play, as they can affect steering response.
Other Key Components
Electrical System
The electrical system is another area where older BMWs can show their age. While the wiring harness is generally durable, connectors and sensors may fail over time.
Common Electrical Issues
– Faulty window regulators
– Malfunctioning sensors that can trigger warning lights
– Aging battery and alternator, which should be tested regularly
In summary, the 1987 BMW 325i can be a reliable classic if you stay on top of maintenance. Understanding the strengths and weaknesses of its key components will help you keep this car running smoothly for years to come.
