Cooling System and Brake Fluid Considerations
Maintaining the cooling system is vital for preventing overheating, which can cause catastrophic engine failure. The 1987 Pontiac Tempest requires a coolant capacity of 13.7 quarts with air conditioning and 13.2 quarts without. The AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a phosphate-, nitrate-, nitrite-, silicate-, borate-, and amine-free formulation that protects all cooling system metals, gaskets, and hoses. It is a pre-mixed 50/50 ethylene glycol solution that offers protection for up to 150,000 miles or five years. For those who prefer to mix their own coolant, the AMSOIL Propylene Glycol Antifreeze and Engine Coolant is a concentrated option that requires mixing with distilled water. It offers the same 150,000-mile protection and greatly surpasses standards for metallic corrosion and erosion.
Brake safety should never be overlooked. The 1987 Pontiac Tempest utilizes a hydraulic brake fluid system compatible with DOT 3 standards. The AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid provides excellent ABS and traction-control responsiveness. It maintains a stable viscosity over a wide temperature range, ensuring consistent brake pedal feel and stopping power in both hot and cold conditions. This synthetic fluid resists moisture absorption, which can lead to corrosion and a spongy brake pedal, making it a superior choice for maintaining the braking system of a vintage vehicle.
Steering and Seasonal Maintenance
The power steering system of the Tempest benefits from the AMSOIL 100% Synthetic Multi-Vehicle Power Steering Fluid. This fluid is formulated for quiet operation and offers strong anti-wear protection. It helps seals remain soft to prevent leaks and resists heat, ensuring the fluid lasts longer than conventional fluids. For seasonal storage, the AMSOIL Gasoline Stabilizer is highly recommended. It helps keep fuel fresh for up to 12 months, protecting against varnish and gum buildup and fighting ethanol corrosion. For long-term storage of the engine, the AMSOIL Engine Fogging Oil is a highly-effective rust preventive that protects internal engine components during periods of inactivity.
About the Vehicle
The 1987 Pontiac Tempest represents a specific era of American automotive history where compact, front-wheel-drive vehicles were becoming increasingly popular. Produced by General Motors, the Pontiac brand was known for offering a blend of performance and practicality, and the Tempest was designed to appeal to drivers looking for a reliable daily commuter that didn’t sacrifice too much in terms of handling or style. The 2.0L four-cylinder engine, often identified by engine code [1] 1 in this model year, was a workhorse designed for fuel efficiency and adequate power for urban and suburban driving environments.
This vehicle was part of the J-body platform, which shared components with other GM compact cars like the Chevrolet Cavalier and Oldsmobile Firenza. The platform was designed to maximize interior space within a compact exterior footprint, making it a favorite among city drivers and families who needed a practical vehicle without the bulk of a full-size sedan. The 2.0L engine typically offered respectable fuel economy for its time, though it was not known for high horsepower outputs. Instead, it provided a balance of torque and reliability that was suitable for everyday commuting, light towing, and general household tasks.
Owners of the 1987 Pontiac Tempest often appreciate its straightforward mechanical layout and ease of maintenance. The front-wheel-drive configuration provided good traction in wet and snowy conditions, making it a versatile choice for various climates. However, like many vehicles of its age, the Tempest is susceptible to certain issues that can be mitigated with the right lubrication products. One common problem is engine sludge buildup in the valve train and oil galleries, particularly in models that were driven primarily in short-stop-and-go traffic. High-quality synthetic motor oils with robust detergent packages help break down this sludge and prevent new deposits from forming, ensuring that oil flow remains unrestricted.
Another prevalent issue in these older engines is oil consumption and blow-by, which can lead to increased emissions and reduced engine performance. The AMSOIL High-Mileage Motor Oil contains seal conditioners that help rejuvenate aged valve stem seals and piston rings, reducing oil consumption and extending the engine’s useful life. Additionally, the cooling system in these vehicles can be prone to corrosion and leaks due to the age of the metal components and the breakdown of original coolant.
