As you know, dielectric grease is great for stopping corrosion and keeping everything running smoothly in your electronics. However, you may be wondering whether dielectric grease is good for spark plugs. In this article, not only will you find out whether dielectric grease is good for spark plugs, you’ll also learn how to apply it, what happens if too much is used, how to remove it, and other frequently asked questions!
So keep reading to find out everything you need to know!
Can You Use Dielectric Grease On Spark Plugs?
Absolutely! If you need to prevent corrosion on your spark plugs and ensure a cleaner connection, then dielectric grease is a great choice for this! However, if you’re not using it yet, remember it’s not necessary, it is recommended to prolong the lifespan of your spark plugs.
How To Apply Dielectric Grease To Your Spark Plugs?
When you’re applying dielectric grease to your spark plugs, you need to take care not to damage the spark plug and spark plug boot. Fortunately, if you follow the advice below, you should be able to apply dielectric grease without a problem!
The first place you can apply dielectric grease is the spark plug boot. To do so, you’ll just need to do the following:
- First things first, you need to make sure the engine has been turned off and cooled down before trying to apply any dielectric grease.
- Once you’ve done this, you just need to pull the plug off the coil pack. Once it’s off grace the metal cover and then spit the boot itself about 1/2 a turn or so. Finally just give the boot a wiggle until it becomes loose.
- Now that the spark plug boot is removed, you just need to apply your dielectric grease. To do so, put some dielectric grease onto a cotton swab and apply it to the inner wall of your spark plug boot.
- Once the dielectric grease has been applied, you just need to put the spark plug boot back in it’s place and it’s good to go again!
What Are The Benefits Of Adding Dielectric Grease To Spark Plugs
If you’re not sure about whether you should add dielectric grease to your spark plugs or not, then here are some of the benefits you can expect to reap from doing so!
It Will Help With Overheating
First of all dielectric grease is going to help with any overheating issues. Because it can be exposed to high temperatures, it acts as a great sealant to stop your spark plugs from overheating!
Prevents Water Damage
Applying dielectric grease to your spark plugs is also going to help stop water damage from occurring. Because silicone is so water resistant, it will stop any water from corroding the spark plugs.
Improved Lifespan
Because dielectric grease is going to prevent water damage and overheating, it goes without saying that it will also improve the lifespan of your spark plugs overall!
What Happens If You Put Too Much Dielectric Grease On Your Spark Plugs?
If you put too much dielectric grease on your spark plugs, then it could result in misfiring. Worst case scenario this can cause engine damage, however, its much more likely that you’ll experience much poorer fuel economy.
As well as this, if you put too much dielectric grease into the spark plug boot, you may even notice it’s hard to push the spark plug itself in.
How Do You Remove Dielectric Grease
If you’ve used too much dielectric grease, then don’t worry, removal isn’t hard. To remove the dielectric grease you’ll need to do two things.
- First of all, use a cotton swab to remove as much of the excess dielectric grease as possible. Put it inside the spark plug boot, and move it around. If the first swab becomes full just use another one.
- Once you’re finding it hard to remove any excess dielectric grease, the next step is too put some alcohol rub on the end of a cotton swab and place it back in the spark plug boot. Keep doing this until all of the dielectric grease has been removed.
FAQ
Here are some frequently asked questions that people have about using dielectric grease on their spark plugs.
When Should You Put Dielectric Grease On Spark Plugs?
While there’s no reason to put dielectric grease on your spark plugs, you can put it on them whenever you want to prolong the life of the spark plugs and reduce the chance of corrosion and overheating.
Can You Put Dielectric Grease On Spark Plug Threads?
You should avoid putting dielectric grease on spark plug threads as this can often make it much harder for electricity to pass easily. As well as this it can also cause misfiring and overheating of the wire, neither of which are going to be good for your car.
Can You Put Dielectric Grease On Electrical Connections?
Dielectric grease can help improve electrical connections when you apply the right amount. As long as there is still a connection between the two parts in questions, then the electricity can even flow through them better, than when dielectric grease isn’t applied!
Can Dielectric Grease Cause A Short?
Dielectric grease is not going to cause a short, as this can only occur when electricity being passed through a wire comes into contact with a neutral wire, allowing the current to jump from the live wire to the neutral wire. In fact, by adding dielectric grease, you’ll even improve the connection between wires, reducing the chance of a short.
What’s The Difference Between Dielectric Grease And Lubricating Grease?
The difference between these two greases is in the name. Lubricating grease will lubricate parts of your machine by reducing the amount of friction, whereas dielectric grease is designed to protect electrical wires and reduce the chances of corrosion or damage occurring.
Because they are so different, it’s important not to use one of these greases in place of the other.
Can You Use Vaseline On Spark Plugs Instead Of Dielectric Grease?
Because Vaseline’s melting point is much lower than dielectric grease, it’s not recommended to use it in place of dielectric grease. If you do, it may end up melting much quicker causing damage to your spark plugs.
Should You Put Dielectric Grease On The Coil Pack?
As well as putting dielectric grease on the spark plugs, it’s also recommended to place dielectric grease on the coil pack as well!
Recap
As you can see, dielectric grease is great for spark plugs, and it’s recommended to use it to reduce corrosion and improve the lifespan of your spark plug! And application of the grease couldn’t be simpler! Just spread some on the inside of your spark plug boot and you’re good to go!
