Essential Fluids for Complete Vehicle Care
When performing maintenance on your 1987 Volvo 740, it is important to consider more than just the engine oil. The cooling system plays a vital role in managing the heat generated by the turbocharger and the engine block. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a robust choice for this vehicle. It features a unique poly-organic acid (OAT) formulation that provides long-lasting protection against corrosion and freezing, ensuring the cooling system remains efficient year-round. For those who prefer a concentrated formula, AMSOIL Propylene Glycol Antifreeze and Engine Coolant offers exceptional thermal stability and is compatible with all other antifreeze colors, allowing for a flexible and effective cooling solution.
The transmission in your Volvo, whether automatic or manual, benefits greatly from high-quality synthetic fluids. For automatic transmissions, the AMSOIL OE Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is a reliable option that guards against leaks and promotes smooth, shudder-free shifts. If your vehicle is equipped with a manual transmission, AMSOIL Super Shift® Racing Transmission Fluid provides extreme heat resistance to virtually eliminate slippage and improve shift performance. This fluid helps protect against wear, ensuring the transmission remains responsive and reliable even under demanding conditions.
The differential and final drive components also require specialized lubrication to handle the torque and stress placed on them. AMSOIL SEVERE GEAR® 80W-90 100% Synthetic Gear Lube is an excellent choice for these applications. It contains friction modifiers suitable for limited-slip applications and helps reduce operating temperatures, extending the life of seals and gears. For those seeking a slightly lower viscosity grade, the AMSOIL SEVERE GEAR® 75W-110 100% Synthetic Gear Lube offers similar benefits with a different viscosity profile, ensuring optimal performance across a wide range of temperatures. Finally, AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid ensures excellent ABS and traction-control responsiveness, providing a stable viscosity over a wide temperature range for safe and confident braking.
Protecting Your Investment During Storage
If your 1987 Volvo 740 is used seasonally or stored for extended periods, specific additives can help preserve its condition. AMSOIL Gasoline Stabilizer helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup that can clog fuel systems. For engine protection during storage, AMSOIL Engine Fogging Oil is highly effective. Designed to protect internal engine components from rust and corrosion, it is ideal for long periods of inactivity. Additionally, AMSOIL P.i.® Performance Improver Gasoline Additive can restore up to 14% horsepower and clean fuel injectors, ensuring the engine performs at its best when you do return to the road.
General maintenance and cleaning are also essential for keeping your classic Volvo in top shape. AMSOIL Synthetic Multi-Purpose Grease resists thermal and oxidation degradation, making it suitable for chassis components. For metal protection against rust and corrosion, AMSOIL Heavy-Duty Metal Protector leaves a long-lasting protective coating that guards against salt and moisture. Cleaning agents like AMSOIL Heavy-Duty Degreaser can quickly remove grease and grime from engine surfaces, while AMSOIL Brake and Parts Cleaner ensures brake components are free of contaminants. For the exterior, AMSOIL Miracle Wash Waterless Wash and Wax Spray offers a fantastic shine with tough protective finish, and AMSOIL Exterior Ceramic Spray provides additional protection against UV rays and water shedding.
Vehicle Background
The 1987 Volvo 740 represents a pivotal moment in the brand’s history, marking the transition from the boxy, utilitarian 240 series to a more modern, aerodynamic design. Part of the “square” generation, the 740 was celebrated for its blend of safety, comfort, and robust engineering. Under the hood, the 2.3L B230 engine, particularly the turbocharged B230FT variant featured in this guide, offered a delightful driving experience. This engine was known for its strong torque and reliability, making the car a favorite among enthusiasts who appreciated its “go-anywhere” capability without sacrificing safety standards.
Volvo’s reputation for building “bunker-like” safety vehicles was firmly established with the 700 series. The 740 featured a rigid body structure, excellent visibility, and a spacious interior that catered to families and those who valued comfort. The turbocharged version, in particular, was a performance-oriented model that brought a level of excitement to the typically conservative Volvo lineup. It was a car that could comfortably transport passengers across long distances while offering a spirited drive on winding roads. The B230FT engine’s turbocharger added a layer of complexity to the engine management, requiring precise lubrication to handle the increased heat and stress. Owners of this vehicle often cite its durability as a primary reason for keeping it on the road for decades.
Despite its robust construction, the 1987 Volvo 740 is not without its challenges, which proper lubrication can help mitigate. One common issue for owners of this era of Volvos is oil sludge buildup, particularly in the turbocharger and oil passages. This can occur if the vehicle is not driven frequently enough to bring the oil to operating temperature or if the oil changes are delayed. Using a high-quality synthetic oil like AMSOIL can significantly reduce the risk of sludge, ensuring that the turbocharger remains properly lubricated and cooled. Another frequent concern is the hardening of seals and gaskets over time, leading to oil leaks. Synthetic fluids, with their superior chemical stability, help keep seals flexible, reducing the likelihood of leaks and preserving the integrity of the engine’s lubrication system.
Corrosion is another battle that owners of older Volvos face, especially if the vehicle has been exposed to harsh winter conditions. The chassis and body of the 740 can be prone to rust if not properly maintained. While regular washing is important, applying protective coatings and using fluids that resist corrosion can make a significant difference. Furthermore, the automatic transmission in some models may exhibit shuddering or rough shifting as the fluid ages. This is often due to the breakdown of the fluid’s additives and the accumulation of wear particles. A synthetic transmission fluid can restore smooth operation, eliminate shudder, and extend the life of the transmission components, ensuring that the driving experience remains as smooth as the day the car was new. By addressing these common issues with high-performance lubricants, owners can keep their 1987 Volvo 740 running reliably for years to come.
Ultimately, the 1987 Volvo 740 B230FT Turbo is a vehicle that rewards attentive owners. Its combination of Scandinavian design, safety features, and turbocharged performance makes it a unique part of automotive history. Whether you are a collector looking to preserve the vehicle’s condition or an enthusiast who enjoys driving a classic car, using the right lubricants is the foundation of keeping this machine in peak condition. The recommended AMSOIL products provide the necessary protection to ensure that your Volvo continues to perform with the reliability and character that made it a legend.
