Porsche 914The Porsche 914 or VW-Porsche 914 was a mid-engined, targa-topped two-seat roadster designed, manufactured and marketed collaboratively by Volkswagen and Porsche from 1969 to 1976. Over the seven model years, Porsche made a number of changes to the 914. Some of these changes were cosmetic and others were in response to changing crash protection standards. The most significant performance upgrade during the vehicle's lifespan was the introduction of anti roll bars, significantly improving the handling, and a change from the "tail shifter" to the "side shifter" gearbox - improving the otherwise vague long linkage.
Porsche 914 FAQ's
How do I adjust the clutch pedal free play in a Porsche 914?
To adjust the clutch pedal free play in a Porsche 914, start by locating the clutch cable adjustment nut near the clutch release lever. Loosen the lock nut with a wrench, then turn the adjustment nut clockwise to increase the free play or counterclockwise to decrease it. Aim for a clutch pedal free play of approximately 10-15mm. Once the desired free play is achieved, tighten the lock nut to secure the adjustment. Test the clutch pedal to ensure proper engagement and disengagement, and readjust if necessary.
How do I change the transmission fluid in a Porsche 914?
To change the transmission fluid in a Porsche 914, start by locating the transmission fluid drain plug underneath the transmission. Place a drain pan underneath the plug, remove the plug with a wrench, and allow the old fluid to drain completely. Once drained, reinstall the drain plug and tighten it to the recommended torque. Locate the transmission fluid fill plug, usually on the side of the transmission, and remove it. Use a suitable fluid pump to add the recommended transmission fluid until it reaches the proper level. Finally, reinstall the fill plug and ensure it is tightened securely.
How do I check and adjust the idle speed in a Porsche 914?
To check and adjust the idle speed in a Porsche 914, start by ensuring the engine is at operating temperature and the car is in park or neutral. Locate the idle speed adjustment screw on the throttle body, which is typically located near the throttle linkage. With the engine running, turn the idle speed adjustment screw clockwise to increase the idle speed or counterclockwise to decrease it. Aim for a stable idle speed between 800-1000 RPM, and recheck the idle speed after adjustment to ensure it remains within the desired range.
How do I check the brake fluid level in a Porsche 914?
To check the brake fluid level in a Porsche 914, start by opening the hood and locating the brake fluid reservoir. The brake fluid reservoir is typically located near the firewall, on the driver's side of the engine compartment. The reservoir cap may have a "Max" and "Min" marking indicating the fluid level. Ensure the vehicle is on a level surface, remove the cap, and visually inspect the fluid level. The fluid should be between the "Max" and "Min" marks. If the level is low, add the appropriate brake fluid type until it reaches the proper level.
How do I check the engine oil level in a Porsche 914?
To check the engine oil level in a Porsche 914, start by parking the car on a level surface and allowing the engine to cool down. Open the rear engine lid and locate the oil dipstick, which is usually yellow or orange. Pull out the dipstick, wipe it clean, reinsert it fully, and then pull it out again to check the oil level. The oil level should be between the minimum and maximum marks on the dipstick.
How do I replace a headlight bulb in a Porsche 914?
To replace a headlight bulb in a Porsche 914, start by opening the front trunk and locating the headlight assembly. Remove the retaining screws or clips that hold the headlight assembly in place, then carefully pull the headlight assembly forward to access the rear of the headlight housing. Twist the bulb socket counterclockwise to remove it from the housing, then pull out the old bulb and insert the new one. Reinstall the bulb socket, secure the headlight assembly back in place, and test the new bulb to ensure proper functionality.
How do I replace the cabin air filter in a Porsche 914?
To replace the cabin air filter in a Porsche 914, start by locating the cabin air filter housing. The housing is usually located behind the glove box or under the dashboard on the passenger side. Open the housing by removing the retaining clips or screws, then carefully take out the old air filter. Clean the housing if necessary, then insert the new cabin air filter with the proper orientation, as indicated by the arrows on the filter. Reinstall the housing and secure it in place, ensuring proper sealing to prevent air leaks.
How do I replace the fuel filter in a Porsche 914?
To replace the fuel filter in a Porsche 914, start by relieving the fuel system pressure by removing the fuel pump fuse or relay and running the engine until it stalls. Once the pressure is relieved, locate the fuel filter, which is typically located along the fuel line, near the fuel tank or engine. Carefully disconnect the fuel lines from the filter, making note of their positions for reconnection. Remove the old fuel filter from its bracket or mounting, then install the new filter in the correct orientation. Reconnect the fuel lines, ensuring they are securely fastened, and test for any fuel leaks before starting the engine.
How do I replace the serpentine belt in a Porsche 914?
To replace the serpentine belt in a Porsche 914, start by locating the belt tensioner, which is usually located near the front of the engine. Use a suitable tool to rotate the tensioner and relieve tension on the belt. While holding the tensioner in the released position, slide the old belt off the pulleys. Take note of the belt routing diagram, often located on the engine bay or in the owner's manual, then install the new belt following the correct routing. Release the tensioner slowly, ensuring the belt is properly seated on all pulleys. Finally, inspect the belt tension and adjust if
How do I replace the spark plugs in a Porsche 914?
To replace the spark plugs in a Porsche 914, start by ensuring the engine is cool and the car is in park or neutral. Locate the spark plug wires connected to the spark plugs, then carefully disconnect them one by one. Use a spark plug socket and a ratchet to loosen and remove the old spark plugs. Before installing the new spark plugs, ensure they are properly gapped according to the manufacturer's specifications. Insert the new spark plugs, tighten them to the recommended torque, and reconnect the spark plug wires in the correct order.
How do I reset the service light in a Porsche 914?
To reset the service light in a Porsche 914, start by turning the ignition key to the "On" position without starting the engine. Press and hold the trip odometer reset button located on the instrument cluster, then turn the ignition key to the "Off" position while still holding the reset button. Continue to hold the reset button for approximately 10 seconds until the service light resets and turns off. Release the reset button, and the service light should now be reset.
How often should I change the air filter in a Porsche 914?
The air filter in a Porsche 914 should be replaced approximately every 15,000-20,000 miles or as recommended by the manufacturer. However, if you frequently drive in dusty or polluted environments, it may be necessary to replace the air filter more frequently to ensure optimal engine performance and fuel efficiency. Regularly inspecting the air filter for dirt, debris, or excessive clogging is also advisable, and if it appears dirty or clogged, it should be replaced regardless of mileage intervals.
What is the recommended tire pressure for a Porsche 914?
The recommended tire pressure for a Porsche 914 may vary depending on the specific model and tire size, so it is important to consult the owner's manual or the label inside the driver's door jamb for the accurate information. However, as a general guideline, the recommended tire pressure for a Porsche 914 is typically around 29-32 PSI for the front tires and 32-36 PSI for the rear tires. Proper tire inflation is crucial for optimal handling, fuel efficiency, and tire longevity.
What type of coolant should I use in a Porsche 914?
In a Porsche 914, it is recommended to use a high-quality ethylene glycol-based coolant with a mixture of 50% coolant and 50% distilled water. This coolant mixture provides optimal freeze and boil protection while also providing proper corrosion protection for the cooling system components. It is important to avoid using plain water or using a coolant that is incompatible with the materials used in the Porsche 914's cooling system, as this can lead to cooling system damage and potential overheating issues.
