Finding Out Reasons for Your Lexus Sc300 Fuel Tank Cap Failure
Often a neglected component in your Lexus Sc300, the fuel tank cap is only given the attention it deserves once issues with it become apparent. Its importance is overlooked because most car owners fail to see the bigger picture-that without a well-conditioned fuel tank cap, your automobile could suffer from significant loss of fuel up to poor engine performance. So before you go straight to checking complex systems in your vehicle to trace down why your car seems inefficient, go over this simple part and find out if it is the cause of such problems. Here are the common reasons for your Lexus Sc300 fuel tank cap failure:
A strong smell of gas could be an indication of leaks in your fuel tank. Check your fuel tank cap if it is properly sealed. You need to take it off and put it on again with just the right amount of tightness. If you are finding it difficult to seat the cap securely, it might already be damaged due to age. Cracks may be present as well. Simply replace it if this is the case.
If you notice a significant decrease of fuel in your tank and you have not changed the way you drive your car, you might want to check your fuel tank cap for a defective gasket. Examine the gasket if it is properly screwed. If it is not, then you have your culprit right there. Sometimes, cracks or cuts could also be found on the gasket's surface, which can eventually cause the fuel inside the tank to evaporate at a rapid pace. You would have to replace the damaged gasket as soon as you can. If the gasket seems hardened, you can simply apply lubricating grease on its surface. However, this quick fix is not meant to be a permanent one. Eventually, you would have to replace your worn-out gasket.
Dirt or corrosion
When you inspect the interior of your fuel tank cap, you may find orange, sticky substances, which are indicative of dirt or corrosion that has formed because of fuel residue. You can simply clean them off with lacquer thinner.
