How to Use a Head Gasket Sealer

What if you found out that your head gasket has little issues? Of course, the first choice you might have is to look for an auto mechanic to check it for you. While this is a good idea, there is also a better option which you in yourself can do. 

There are certain methods you can do to fix the head gasket sealer. It is not a complicated process, and surely, you can do it by yourself. Check it out, and there’s no need for you to dig in in this predicament. 

Checking Your Head Gasket 

The very first step you must do is to properly check your head gasket if you’re already suspecting that something is wrong, before making a firm judgment, better to double-check it before making a conclusion. 

So, what are the signs that your head gasket is leaking, or it has some issues? 

Here are the things you can do. 

Check the oil filler cap’ bottom 

When the head gasket produces a “mayonnaise” below its filler cap, there is something going on with it. It is called the “mayonnaise” layer because it resembles white and creamy color like that of a condiment. If you don’t see this creamy thing, it doesn’t also mean that your head gasket has no problem at all. 

Steps on Using the Head Gasket Sealer 

Step 1 – Jack up your vehicle and place the jack stand below the vehicle. 

Step 2 – Place a container under the radiator. This container should be enough to hold all the coolant. You may refer to the manual of how much coolant you will give out. 

Step 3- Open the petcock of the radiator and let the coolant flow inside the container. Make sure that the coolant will not spill in the ground. 

Step 4- When you see that the coolant already dry out, return the petcock. 

Step 5 – Fill the radiator with water. If you see that its cap is damaged or worn out, replace it with a new one. 

Step 6 – In order not to engage the coolant while you are adding a sealant, you must disconnect the thermostat. With the airflow, the thermostat will allow the coolant to cool off and pass. 

Step 7 – After doing the above step, it is now your time to set the heater in high, and you may now start your vehicle. It helps in circulating the water through the whole system as well as dry the remaining coolant. 

Step 8 – Don’t forget to check the temperature gauge. When the vehicle is overheating, you need to turn it off.

Filling the System with Head Gasket Sealer 

Step 1 – The same process on how you drain the coolant, open the petcock, and drain the water. 

Step 2- Since the water is already contaminated, you must drain the water with a container. After doing so, close the petcock again. When doing the first step, make sure to reconnect the thermostat since you disconnected it. 

Step 3 – Choose the best sealant for your car and make a mixture of water, which should be 50/50 in amount. You may keep on adding extra coolant until it will reach its maximum capacity. 

Step 4 – Follow the manual’s instructions and open the radiator. Once opened, you may now put the head gasket sealer. 

Step 5 – The next step is to drive your car for 15 to 20 minutes. You need to do this since the sealer will travel through the system before it reaches the head gasket. 

Step 6 – When you observe signs of overheating in your car, stop driving immediately. Stop your car for 15 to 20 minutes. 

Step 7 – Before proceeding to the next step, sit your car for a few hours. 

Step 8 – Evaluate and check your head gasket if it still has leakage. If you see no signs of leakage and the issue has been fixed, then your problem is already solved. 

Conclusion

There were times that no matter how good the solution you made, your head gasket is still not doing better. If this is the case, the only solution is to replace it with a new one.
