The Best Years For Volvo 740 And Some To Avoid

The Volvo 740, a staple of 1980s and early 1990s automotive engineering, is renowned for its durability, reliability, and safety. While these cars are generally robust, certain model years and configurations offer a superior ownership experience compared to others. This guide aims to provide potential buyers with the knowledge necessary to select the best Volvo 740 for their needs, while also highlighting model years that might present potential issues.

Volvo 740 Model Year Comparison: Key Considerations

Detailed Explanations

1985-1988 (Early Models):

These early models represent the quintessential Volvo 740. The B230F engine, a 2.3-liter naturally aspirated four-cylinder, is a workhorse known for its longevity. Importantly, these engines are non-interference, meaning that if the timing belt breaks, the valves will not collide with the pistons, preventing catastrophic engine damage. The simpler design and fewer electronic components make these models relatively easier to maintain and repair, often requiring less specialized tools and knowledge. However, potential buyers should be prepared for less refined interiors and older technology, such as earlier versions of Bosch fuel injection systems, which may not be as efficient as later iterations.

1989-1990 (Mid-Production):

The 1989 and 1990 Volvo 740s saw improvements in fuel injection systems, transitioning to the Bosch LH 2.4 system. This system offered better fuel efficiency and smoother engine performance. Interior enhancements included minor cosmetic updates. Safety features began to be implemented, with driver-side airbags appearing as an option, depending on the specific market. ABS (Anti-lock Braking System) also became more prevalent, offering improved braking performance, especially in adverse conditions. A significant drawback of these years is the continued use of older wiring harnesses. These harnesses are prone to cracking and deteriorating, especially in hotter climates, leading to electrical issues. Early versions of electronically controlled automatic transmissions could also exhibit problems.

1991-1992 (Late Production):

The final years of the Volvo 740 production run showcase the most refined versions of the car. Interiors were upgraded with better materials and improved sound insulation, creating a more comfortable driving experience. Build quality generally improved, resulting in fewer rattles and squeaks. Safety features were further enhanced, with optional passenger-side airbags becoming available. Climate control systems were also improved, offering more precise temperature regulation. However, the increased complexity of the electronics can make diagnosis and repair more challenging. The catalytic converters on these models may also require replacement due to age and mileage.

Specific Considerations and Problem Areas

Beyond the general model year differences, several specific areas deserve attention when evaluating a Volvo 740:

• Wiring Harness Degradation: As mentioned earlier, the wiring harnesses in all Volvo 740s are susceptible to degradation due to age and heat. This can lead to a variety of electrical problems, including intermittent failures of sensors, lights, and other components. Thoroughly inspect the wiring, especially in the engine compartment and under the dashboard.

• Automatic Transmission Issues: The electronically controlled automatic transmissions in later models can be prone to problems, such as slipping or erratic shifting. Ensure the transmission shifts smoothly through all gears and that there are no unusual noises or vibrations. Regular fluid changes are crucial for maintaining transmission health.

• Rust: While Volvo 740s are generally well-protected against rust, rust can still occur, especially in areas that experience harsh winters and road salt. Inspect the undercarriage, rocker panels, and wheel wells for any signs of rust.

• Fuel Injection System Components: Components of the Bosch fuel injection systems, such as fuel pumps, fuel injectors, and mass airflow sensors, can fail over time. Look for signs of poor engine performance, such as rough idling, stalling, or poor fuel economy.

• Climate Control System: The climate control systems in Volvo 740s can be complex and prone to leaks. Ensure that the air conditioning blows cold and the heater blows hot. Also, check for any unusual noises or smells coming from the system.

• Suspension Components: The suspension components, such as shocks, struts, and bushings, can wear out over time, leading to a bumpy ride and poor handling. Inspect the suspension for any signs of leaks or damage.

Tips for Buying a Used Volvo 740

• Thorough Inspection: Before purchasing a Volvo 740, have it thoroughly inspected by a qualified mechanic. This will help identify any potential problems that may not be immediately apparent.

• Check the Maintenance Records: Review the maintenance records to see how well the car has been maintained. Regular maintenance is crucial for ensuring the longevity of a Volvo 740.

• Test Drive: Take the car for a test drive to assess its overall performance. Pay attention to the engine, transmission, brakes, and suspension.

• Consider the Mileage: Volvo 740s are known for their longevity, but high mileage can still take its toll. Consider the mileage when evaluating the car's overall condition and price.

• Factor in Repair Costs: Be prepared to factor in potential repair costs. Even well-maintained Volvo 740s may require repairs as they age.
