* Engine Oil: Use the oil grade specified in your owner's manual. This will likely be a 10W-30 or 10W-40, but *always* check your owner's manual for the exact recommendation. The type (conventional, synthetic blend, or full synthetic) is also a choice you should make based on your driving conditions and preference, again consulting your manual if unsure.
* Transmission Fluid: For the manual transmission, Ford typically recommended GL-3 or GL-4 gear oil. The specific weight will depend on your climate and usage; check your owner's manual for the correct specification. Using the wrong type (such as ATF - automatic transmission fluid) can severely damage the transmission.
* Coolant: Use a 50/50 mix of coolant and distilled water. Ford typically used a green coolant (ethylene glycol based) in that era, but you can use a universal coolant compatible with aluminum engines. Again, consult your owner's manual. Never mix different types of coolant.
* Brake Fluid: Use DOT 3 brake fluid. DOT 4 is also generally compatible, but DOT 3 is usually preferred for older vehicles.
* Power Steering Fluid (if equipped): If your truck has power steering, check your owner's manual for the recommended power steering fluid. It's often a type of ATF (automatic transmission fluid), but *confirm this with your manual*.
Crucially: Always refer to your owner's manual for the exact specifications and capacities for your particular vehicle. The information above is general guidance and might not be entirely accurate without knowing your specific truck's options and conditions. Incorrect fluids can severely damage your vehicle's components.
