The Volvo 740 series, produced from 1984 to 1992, has long been celebrated for its reliability, safety, and durability. However, like any vehicle line, certain model years have proven more problematic than others. This comprehensive guide will delve into the Volvo 740 years to avoid, helping potential buyers and current owners navigate the complexities of this iconic Swedish automobile.
| Model Year | Recommendation | Common Issues |
|---|---|---|
| 1984-1985 | Avoid | Early production issues, less refined |
| 1986-1988 | Caution | Improved, but still some reliability concerns |

Understanding the Volvo 740 Series
Before diving into specific years to avoid, it's crucial to understand the Volvo 740 series as a whole. Introduced in 1984 as a replacement for the 240 series, the 740 represented a significant step forward in Volvo's design and engineering philosophy. It offered improved aerodynamics, more powerful engines, and enhanced safety features compared to its predecessor.
The 740 was available in both sedan and wagon body styles, with various engine options including naturally aspirated and turbocharged four-cylinder engines, as well as a V6 in some markets. Over its production run, the 740 underwent several updates and refinements, which is why certain years are more desirable than others.
Volvo 740 Years to Avoid
1984-1985: The Early Years
The initial years of the Volvo 740 production are generally considered the least desirable. These early models often suffered from:
- Teething problems common to newly introduced vehicle lines
- Less refined engine management systems
- Potential issues with early production quality control
Engine Concerns: The B230F engine used in these early models was known to have issues with oil leaks and head gasket failures. While these engines could last a long time with proper maintenance, they required more attention than later versions.
Electrical Issues: Early 740s were prone to electrical gremlins, particularly with the climate control system and power windows. These issues could be frustrating and expensive to repair.
"I bought an '85 740 as my first car. While I loved its character, I spent more time fixing electrical issues than driving it. Wish I'd gone for a later model."[1]
1986-1988: Improvement, but Caution Advised
The years 1986 to 1988 saw significant improvements over the initial models, but they still fall into the caution category. Here's why:
- Improved engine management systems, but still not as refined as later models
- Persistent issues with some electrical components
- Turbo models from these years could suffer from oil leaks and turbocharger failures
Transmission Concerns: The automatic transmissions used in these years, particularly in high-mileage vehicles, could be prone to failure. If you're considering a 740 from this period, a thorough inspection of the transmission is crucial.
Rust Issues: While Volvos are generally known for their durability, models from these years could suffer from rust, especially in areas where road salt is used heavily. Check the lower body panels, wheel wells, and underbody carefully.
The Turning Point: 1989 and Beyond
1989-1990: The Sweet Spot
The years 1989 and 1990 mark a significant improvement in the Volvo 740 series, making them recommended choices for buyers. Here's what changed:
- Introduction of the LH-Jetronic 2.4 fuel injection system, improving reliability and performance
- Enhanced rust protection with better galvanization
- Refined interior with improved materials and build quality
Engine Improvements: The B230F engine received updates that addressed many of the oil leak issues prevalent in earlier models. The turbo variants (B230FT) also saw improvements in reliability during these years.
Safety Enhancements: While all 740s were known for their safety, the 1989-1990 models received additional reinforcements and improved crumple zones, making them even safer than their predecessors.
"My 1990 740 Turbo has been the most reliable car I've ever owned. Over 300,000 miles and still running strong with regular maintenance."[2]
1991-1992: The Golden Years
The final two years of Volvo 740 production are widely regarded as the best in the series. If you're in the market for a 740, these are the years to target. Here's why:
- Culmination of all previous improvements and refinements
- Most reliable engine and transmission combinations
- Enhanced comfort features and interior quality
Engine Reliability: By this point, Volvo had ironed out most of the kinks in their engine lineup. The B230F and B230FT engines from these years are known for their longevity and reliability when properly maintained.
Improved Electronics: Many of the electrical issues that plagued earlier models were resolved by this time, resulting in more dependable operation of various systems.
Resale Value: Due to their reputation for reliability and the fact that they represent the pinnacle of 740 development, 1991-1992 models often command higher resale values.
Common Issues Across All Volvo 740 Years
While certain years are more problematic than others, there are some issues that can affect Volvo 740s across all model years. Being aware of these can help you maintain your vehicle or make an informed purchase decision:
- Flame Trap Clogging: The flame trap (part of the crankcase ventilation system) can become clogged over time, leading to oil leaks and increased engine pressure. Regular cleaning or replacement is necessary.
- Suspension Wear: The front control arm bushings and rear trailing arm bushings are known wear items. Regular inspection and replacement when necessary can prevent handling issues.
- Cooling System Maintenance: The plastic components in the cooling system can become brittle with age. Proactive replacement of the expansion tank and other plastic parts can prevent overheating issues.
- Turbo Oil Lines: In turbocharged models, the oil feed and return lines to the turbocharger can deteriorate over time. Regular inspection and timely replacement are crucial to prevent catastrophic engine damage.
Maintenance Tips for Longevity
Regardless of the model year, proper maintenance is key to ensuring the longevity of your Volvo 740. Here are some essential tips:
- Regular Oil Changes: Use high-quality oil and change it every 5,000 miles or as recommended in the owner's manual.
- Timing Belt Replacement: Replace the timing belt every 70,000 miles or as specified by Volvo to prevent engine damage.
- Coolant Flush: Perform a coolant flush every 30,000 miles to prevent corrosion and maintain proper engine temperature.
- Transmission Service: Regular transmission fluid changes can significantly extend the life of the automatic transmission.
- Rust Prevention: Regular undercarriage cleaning and application of rust inhibitors can help protect against corrosion, especially in areas with harsh winters.
Making the Right Choice
When considering a Volvo 740, the model year should be just one factor in your decision-making process. Here are some additional points to consider:
- Service History: A well-maintained 1986 740 could be a better choice than a neglected 1992 model. Always prioritize maintenance history over model year.
- Mileage: While Volvo 740s are known for their longevity, lower mileage examples will generally require less immediate maintenance.
- Rust Inspection: Thoroughly check for rust, especially on earlier models or vehicles from areas with harsh winters.
- Test Drive: Pay attention to transmission shifts, engine performance, and any unusual noises during a test drive.
- Professional Inspection: If possible, have a Volvo specialist inspect the vehicle before purchase. They can identify model-specific issues that a general mechanic might miss.
Conclusion
The Volvo 740 series offers a unique blend of safety, durability, and classic Swedish design. While the early years (1984-1985) are generally best avoided due to reliability concerns, and the middle years (1986-1988) should be approached with caution, the later models (1989-1992) represent the pinnacle of 740 development and reliability.
Ultimately, the best Volvo 740 for you will depend on your budget, intended use, and willingness to perform maintenance. By understanding the strengths and weaknesses of each model year and being prepared to address common issues, you can enjoy the unique experience of owning this iconic Volvo model for many years to come.
