Jeep Grand Cherokee Oil Filler Cap
How to Detect the Causes behind Jeep Grand Cherokee Oil Filler Cap Problems
Your Jeep Grand Cherokee oil filler cap seals fuel inside the reservoir. Because of its relatively small size, you may think that this component is not important. That's not true. You must realize that this cap plays a huge part in improving your gas mileage. Without it, your gasoline won't last for miles. That's why you must act quickly when your gas cap begins to show signs of failure. Get ready to do some troubleshooting to find out what causes your cap to malfunction.
Minor issues involve an improperly installed oil filler cap. When you're in a hurry, you tend to forget to tighten the cap firmly. A loose gas cap usually turns the "Check Engine" light on. But there's a more efficient way that can help you verify if the problem is really coming from the oil filler cap. You need to use an automotive scan tool. Simply plug it to the outlet under your vehicle's dashboard. Wait for a few minutes until you see the code flashed on the screen. If you see the error code "Po44o," it means that your gas cap is loose. In this case, you just need to tighten the cap to fix the issue.
Fuel leak is perhaps the most serious problem you'll ever experience with a broken oil filler cap. Leak is often caused by a missing cap. This happens when the cap is loose, and you're not aware of it. Gradually, the cap will come off from its mounting. To check, you must open your hood. Slowly twist the cap to feel if it's tightly secured to the oil reservoir or not. Touch the other components inside the hood compartment as well to detect oil seepage. Replace your damaged cap and wipe off oil residue. Remember, fuel leak is very dangerous; it can initiate fire.
Other costly problems
A damaged oil filler cap has long-term effects and one of these can affect your budget in a very bad way. If you don't replace broken cap, you just let yourself spend plenty of cash for gallons of fuel you're not able to use. Gasoline is a highly volatile liquid that evaporates and escapes in the atmosphere through the cracks and holes of a bad fuel cap. To prevent this, inspect your cap regularly. Take it out of the vehicle to thoroughly examine its condition.
