What is a Head Gasket Sealer

First of all, a head gasket is an important piece in any car which separates the engine block and cylinder head. It seals the cylinders to allow for the greatest degree of compression and reduce the leakage of oil or coolant that can get into the cylinders. The head gasket is essentially the most important sealing application which exists in any given engine. If a head gasket gets blown it can create a world of difficulty for whoever owns the car. This is also where head gasket sealant comes into play.

A head gasket sealer can also be called a gasket sealant. It comes in the form of either a spray, glue, or paste, and the purpose it serves it to keep the gasket in place and restrain it from moving. Gasket sealer can also make it less likely for car parts to rub against one another and it will help to reduce a number of fluid leakages you experience. Over time sealants may wear out just like anything else. If you want a sealant which will last longer and work best, then it’s vital to understand what types of sealant are available and which are the best quality. Basically, it’s important to get the best head gasket sealer.


How to Prevent Blowing A Head Gasket

Blowing a head gasket can be pretty bad for your car, needless to say. Thankfully there are certain things you can do in order to prevent this from happening. If you just do a little bit of maintenance on your head gasket then it will probably last as long as you drive the car. Just a little bit of preventative care can go so far, as just about anyone knows who owns a car. Keeping up with regular maintenance may cost money but in the long run, it could save you a small fortune.

Every 3,000 miles change the fluids in your car. This should be done consistently but you can do it from home if you don’t want to take it to an auto shop. One of the most common reasons that people end up with blown head gaskets is simply because they don’t have enough engine coolant. This is an easy thing to avoid if you just keep on top of it.

When you drive don’t accelerate so quickly. Sudden, fast acceleration can bump up the temperature of the engine significantly. This, in turn, may lead to a head gasket either warping or cracking, neither of which are good. Rather than revving the engine the best way to drive is to accelerate slowly and avoid pushing the gas pedal any further than halfway.

If your engine does begin to overhead then pull over. Once again the heat in the engine can lead to a damaged head gasket, so if you know that your car is overheating just turn the engine off so that it can cool down. In some cases, an engine may be consistently hotter than it should be, and this is a problem that should be resolved as it could lead to bigger problems.


How to Use a Head Gasket Sealer

Surprisingly head gasket sealer is very easy and simple to use. There are only a few basic steps to follow and as long as you stick to the directions everything should go smoothly and there should be no issues involved. Using head gasket sealer is something that you can do yourself from home, you don’t have to take the car to a shop or have a professional help you.

The other good news is that, like with anything involving cars, there are directions included. When you do buy head gasket sealer it will certainly come with instructions. These should be simple and easy to read and follow, but to give you an idea of how to use head gasket sealer here are some basic directions that should help.


1.  Clean Cooling System

Before you can apply the gasket sealer you should have a cooling system that is free flowing and clean.


2. Take off Thermostat and Flush System

Before using the coolant you will probably need to remove the thermostat then flush the cooling system with some type of flushing agent and then flush again with water.


3. Fill with Water

Pour water into the cooling system but leave enough space for the amount of head gasket sealer which is required. There should be a table which tells you.


4. Engine Must be Cold

Before you actually begin the engine has to be cold, this is very important. The next step is to take off the radiator cap, start the engine, then blast the heater.


5. Slowly Add Head Gasket Sealer

It is very important that you pour the sealer into the radiator very slowly. It should take you around 1 minute to add the whole bottle. Let the car idle for about 50 minutes with the cap on.


6. Finishing Steps

Allow the engine to cool and then install the new thermostat, then drain fluid and add antifreeze.


Ultimately this entire process should not take too long nor require any great degree of effort or skill. As you can see adding head gasket sealer is pretty easy, just carefully read the directions, follow them through exactly how they say, and make sure to follow all safety precautions and warnings. If you add the sealer correctly and you find the right kind then it should help solve some of your problems.
