The engine in the 1984 Ford EXP is a unique proposition for enthusiasts. Powered by a 1.6L inline-four turbocharged engine (Engine Code [8] 8 Turbo), it was designed to deliver spirited performance from a compact platform. This specific engine requires an oil viscosity that can handle the heat generated by the turbocharger while maintaining proper lubrication during cold starts. The recommended oil capacity for this engine is 4.0 quarts, including the filter. Ensuring the oil level is checked after the refill is crucial for maintaining the turbo’s lifespan. The oil drain plug torque should be tightened to between 15 and 25 ft/lbs to prevent leaks without damaging the threads.
For the cooling system, the 1984 Ford EXP requires a substantial amount of fluid to manage the heat generated by the turbocharged powertrain. The total coolant capacity is 7.9 quarts. Using a high-quality antifreeze is vital to prevent corrosion and overheating, which can be detrimental to an older vehicle with potential wear in the cooling system passages. AMSOIL Passenger Car & Light Truck Antifreeze & Coolant is a great choice for meeting or exceeding original equipment manufacturer requirements, ensuring protection for up to five years or 150,000 miles. The AMSOIL Propylene Glycol Antifreeze and Engine Coolant option provides a safer, environmentally friendly alternative that requires mixing with distilled water for optimal performance.
Transmission maintenance is equally critical for this model. The automatic transmission (specifically the ATX 3-speed) has a total fill capacity of 8.3 quarts. For manual transmissions, which were also available in various configurations, the fill capacities range from 5.3 pints to 6.1 pints depending on the specific gear count. The power steering system, which relies on fluid compatible with automatic transmission specifications, benefits from the use of synthetic transmission fluids that resist heat and sludge. The AMSOIL Signature Series Multi-Vehicle 100% Synthetic Automatic Transmission Fluid is an excellent choice that withstands the rigors of heavy use and elevated temperatures. The manual transmission drain plug torque specification is between 29 and 43 ft/lbs. Using a synthetic transmission fluid ensures smooth shifting and protects against the wear that can occur in these older gearboxes, extending the life of the drivetrain components.
Fluid maintenance extends beyond just the engine and transmission. For the braking system, the 1984 Ford EXP utilizes a hydraulic system requiring fluid that meets Ford specifications WSS-M6C65-A1. AMSOIL DOT 3 and DOT 4 100% Synthetic Brake Fluid is an ideal replacement, offering stable viscosity and excellent responsiveness for ABS and traction control systems. Additionally, for owners looking to improve fuel economy and engine performance, AMSOIL P.i. Performance Improver Gasoline Additive can restore lost horsepower and clean fuel injectors, making a noticeable difference in how the turbocharged engine responds. Seasonal storage also requires attention; for vehicles that see less frequent use, AMSOIL Gasoline Stabilizer can keep fuel fresh for up to 12 months, protecting against varnish and ethanol corrosion.
