My Ford F4 will turn over but it won't stay on. What could be causing this?
There might be something wrong with your Ford F4's carburetor. Check the carburetor and see if the choke is closing properly. If it's not working normally, adjust it. It's also possible that there's a vacuum leak in the engine somewhere, so use a vacuum gauge to check and fix the leak if you find it. You might have put the base gasket on the wrong side or the gasket is not compatible with the carburetor and engine combination and resulted in the leak. Another possible cause for your carburetor problem is that the choke pull-off setting is incorrect. The carburetor may have been bumped for some reason, which accidentally changed its settings. Try to adjust it to factory specifications if you can. If the choke is working fine and there isn't a leak in the engine, the fast idle RPM might be set too slow and needs to be adjusted to the recommended settings.
My Ford F4 truck makes this weird noise that I can't identify. How do I troubleshoot this?
When your Ford F4 truck is making unusual sounds even though it's running properly, you still need to identify the source as it might be a symptom of an underlying problem. To locate where the sound is coming from, get an old stethoscope, take off the disc and insert a piece of tubing in its place. Then put the plugs in your ears, run your truck's engine, and move the tube end of the stethoscope around the hood. The stethoscope should amplify the sound as you place the tube near the component that's causing the noise. If you hear something ticking, shut off your engine, wait 10 minutes for it too cool and the oil to settle, and then check the oil level. If there's enough oil left, there might be a problem with the valve adjustment. If you hear a whistling sound from under the hood, inspect the hoses for vacuum leaks.
The headlight beams of my Ford F4 do not light up the road ahead as well as it should. What could be the problem?
The headlights of your Ford F4 are dirty, or there's fogging inside the lens cover. It's also possible that the covers of the headlights are discolored, or maybe the headlights are just not aimed properly. Because most of the possible problems have something to do with the headlights itself and the lens cover, the first thing you should do is visually inspect the headlights. Dirt on the outside or moisture inside the cover reflect light back and reduce the brilliance of your truck's headlights. If you do find dirt, simply clean it up. However, if there's moisture inside, then it means something is leaking. Check the housing or the gasket that seals the housing to the cover for any cracks and other signs of damage that could cause the leak. Moisture is difficult to remove from a sealed housing. You will have to drill one or two small vent holes in the top of the headlight housing during dry weather, and park your truck outside during the day so that the sun shines directly on the headlights. The moisture should evaporate through the vent holes you made after a few hours.
