Volvo S70: A Comprehensive Guide

The Volvo S70 is a compact executive car manufactured and marketed by Volvo Cars between 1996 and 2000. Essentially a facelifted and renamed Volvo 850, the S70 represented Volvo's move towards more modern styling and improved safety features. It falls into the category of a compact executive car, offering a balance of comfort, performance, and practicality, aimed at families and individuals seeking a refined and safe driving experience.

Generations

First Generation (1996-2000)

The S70 effectively represents a single generation, although it underwent minor changes during its production run. Key features and changes include:

  • Launch (1996): Replaced the Volvo 850. Exterior styling was refined, with a more rounded front fascia, updated taillights, and redesigned interior components.
  • Engine Options: A range of inline-5 cylinder engines were offered, including naturally aspirated, light-pressure turbo (LPT), and high-pressure turbo (HPT) variants. Diesel engines were also available in some markets. The famous T5 engine remained a prominent performance option.
  • Trim Levels: Offered in various trim levels, typically including base, GLT, and T5, each with increasing levels of equipment and performance.
  • Safety Features: Continued Volvo's emphasis on safety with standard features like dual front airbags, side impact protection system (SIPS), and anti-lock brakes (ABS). Later models featured improvements to these systems.
  • Drivetrain Options: Offered in both front-wheel drive (FWD) and all-wheel drive (AWD) configurations, the latter providing enhanced traction in adverse conditions.
  • End of Production (2000): Replaced by the Volvo S60, marking a complete redesign of the Volvo sedan range.

Reliability & Common Issues

The Volvo S70, like the 850 before it, is known for its robust build quality and potential for high mileage. However, as with any older car, certain issues are more common than others. Regular maintenance is key to ensuring long-term reliability.

Engine Related Issues:

  • PCV System Clogging: A common issue is clogging of the positive crankcase ventilation (PCV) system. Symptoms include rough idle, oil leaks, and excessive crankcase pressure. Regular cleaning or replacement of PCV components is recommended.
  • Turbocharger Problems (T5/HPT Models): Turbocharged models are susceptible to turbocharger failure due to oil starvation or wear. Listen for unusual noises and check for oil leaks. Regular oil changes with high-quality synthetic oil are crucial for turbo longevity.
  • Cooling System Issues: Radiator leaks, hose failures, and water pump issues are relatively common. Regular coolant flushes and inspections are necessary to prevent overheating.
  • Timing Belt Replacement: It is *essential* to adhere to the recommended timing belt replacement interval (typically every 70,000 miles or 110,000 km) to prevent catastrophic engine damage.
  • Oil Leaks: Valve cover gaskets, rear main seals, and oil cooler lines are prone to leaking as the car ages.
  • MAF Sensor Failure: The Mass Air Flow (MAF) sensor can fail, leading to poor running conditions. Symptoms include poor fuel economy, rough idling, and difficulty starting.

Transmission Related Issues:

  • Automatic Transmission Problems: The automatic transmissions used in the S70 can experience issues such as slipping, harsh shifting, or failure, especially if not properly maintained. Regular fluid changes using the correct Volvo-specified fluid are crucial.
  • Manual Transmission Clutch Wear: Manual transmission models may require clutch replacement over time.

Suspension & Brakes:

  • Suspension Component Wear: Bushings, ball joints, and struts can wear out, leading to poor handling and ride quality. Regular inspection and replacement of worn components are important.
  • ABS Issues: The ABS system can experience issues with wheel speed sensors or the ABS control module.

Electrical Issues:

  • Central Locking System: The central locking system can be prone to failures.
  • Power Window Regulators: Power window regulators can fail, making it difficult or impossible to raise or lower the windows.
  • Climate Control Issues: Problems with the climate control system, such as faulty blend door motors or compressor failures, can occur.
  • Instrument Cluster Issues: Occasional issues with the instrument cluster, such as dimming lights or malfunctioning gauges, can arise.

Driving Experience

Pros:

  • Comfortable Ride: The S70 offers a comfortable and composed ride, making it well-suited for long journeys.
  • Spacious Interior: The interior is spacious, providing ample room for passengers and cargo.
  • Solid Build Quality: Volvos of this era are known for their robust construction and durability.
  • Good Safety Features: The S70 was equipped with a comprehensive array of safety features for its time.
  • Available AWD: The AWD versions offer excellent traction and stability, especially in inclement weather.
  • Powerful Engines (T5): The T5 models offer engaging performance and a distinctive engine note.

Cons:

  • Fuel Economy: Fuel economy can be relatively poor, especially with the turbocharged engines.
  • Repair Costs: Parts and labor for repairs can be more expensive than for some other vehicles in its class.
  • Age Related Issues: As an older car, expect to deal with age-related wear and tear.
  • Turning Radius: The S70's turning radius can feel large compared to modern cars.

Overall, the Volvo S70 offers a comfortable and safe driving experience, with a focus on practicality and durability. The T5 models provide a more sporty and engaging driving experience.

Buying Advice

Years to Look For:

  • Late Production Models (1999-2000): These models may have benefited from minor improvements and refinements implemented throughout the production run.
  • Well-Maintained Examples: Prioritize examples that have been meticulously maintained with documented service history.

What to Avoid:

  • Neglected Examples: Avoid cars with poor maintenance records or obvious signs of neglect.
  • Cars with Extensive Rust: Check carefully for rust, especially in areas such as the wheel arches, sills, and undercarriage.
  • Cars with Unexplained Mechanical Issues: Be wary of cars with unresolved mechanical problems, as these can be costly to repair.
  • High Mileage without Service Records: High mileage cars can still be good buys, but only if there's evidence of proper maintenance.

Key Checks Before Buying:

  • Timing Belt Condition: Verify that the timing belt has been replaced according to the recommended interval.
  • PCV System Function: Check for signs of PCV system clogging, such as oil leaks or excessive crankcase pressure.
  • Transmission Performance: Test drive the car and pay attention to the smoothness of the transmission shifts.
  • Cooling System Condition: Inspect the radiator, hoses, and water pump for leaks or signs of wear.
  • Electrical System Function: Check all electrical components, including the lights, windows, locks, and climate control system.
  • Turbocharger Condition (T5/HPT Models): Listen for unusual noises from the turbocharger and check for oil leaks.
  • Rust Inspection: Thoroughly inspect the car for rust, paying attention to common problem areas.
  • Obtain a Pre-Purchase Inspection (PPI): Have a qualified mechanic perform a pre-purchase inspection to identify any potential issues.

By carefully researching and inspecting potential purchases, you can find a reliable and enjoyable Volvo S70 that will provide years of service.
