How To Clean A Head Gasket And Fix It

Cars are one of the most important aspects of our lives, and as such, they deserve to be treated with the utmost care. One of the most common problems with cars is head gaskets, which can become contaminated with oil and dirt.

If left untreated, this can cause serious engine problems. In this blog post, we will show you how to clean a head gasket and fix it in case it becomes damaged. By following these simple steps, you will be able to save your car from major repair costs.

What is a Head Gasket?

A head gasket is a type of airtight seal that separates the engine block from the cylinder head. The purpose of a head gasket is to keep the engine cool and allow it to run without any problems.

When the head gasket fails, oil leaks between the engine block and cylinder head and causes serious damage. To fix a head gasket, you will need to remove the engine block and replace the seal.

How do you Replace a Head Gasket?

If your head gasket has gone bad and is leaking oil, it’s time to replace it. This article will show you how to do the replacement, including the removal of the old head gasket and installation of the new one.

Make sure you read through all the steps before beginning so that you don’t make any mistakes!

1. Park your car in a safe place where you can leave it for the duration of the job.

2. Remove the intake manifold by unscrewing the eight bolts that hold it in place. It’s best to use a cranked-up jack to help lift it off while avoiding contact with the engine or transmission beneath it.

3. If your car has an air injection system, remove the air pump by unscrewing its three bolts. Be careful not to drop this important part!

4. On certain models, you’ll also need to remove the cam cover and fan belt cover before proceeding further down into the engine bay. Check your vehicle’s owner’s manual for specific instructions.

5. Underneath all of these parts is your radiator support bracket, which needs to be removed in order to get to your engine coolant reservoir. Simply loosen its four screws at either end and pull it out from underneath; be careful not to pinch or tear any wiring harnesses as you go!

6. Carefully remove the engine coolant reservoir by pulling straight up on its retaining ring until it releases

What are the Signs that a Head Gasket Needs to be Replaced?

If you have a head gasket that is starting to fail, it can be a sign that it needs to be replaced. Here are some signs that your head gasket might need to be replaced:

1. Your car has been overheating or smoking a lot lately.

2. You have had multiple engine light codes come up.

3. The engine has been making strange noises, like loud knocking or hissing.

4. There is oil or fluid leaking from the engine compartment.

How do you Clean and Fix a Head Gasket?

If your car’s engine is making strange noises or the head gasket has come off, it’s time to take it in for servicing. Head gaskets are typically a cheap and easy fix, but you need to be careful when cleaning them so you don’t damage the engine.

To clean a head gasket, first, use a rag to clean any oil or grease off of the surface. Next, pour some anti-freeze or boiling water into a sink and pour it over the rag. Be sure to rinse off all the dirt and debris before putting the rag back together and placing it back onto the gasket.

When replacing a head gasket, make sure that you use an approved sealant. If you don’t replace the sealant, your engine could leak again in the future.

Difference Between An Aluminum and A Cast Iron Head Gasket

Cast iron head gaskets are generally considered to be more durable than aluminum ones, though the two materials have their own advantages and disadvantages. Cast iron is heavier and has a rougher surface than aluminum, which can increase friction between the head and cylinder walls. However, cast iron also has a much longer lifespan than aluminum because it doesn’t corrode.

Aluminum head gaskets are generally cheaper than cast iron ones and they don’t require as much maintenance. However, they can be damaged by high temperatures or acidic gases, and they don’t resist corrosion as well as cast iron.


If your car’s engine is sounding worse and worse, and you think it might be time to take it in for a checkup, If you think its the head gasket and you can fix it yourself, you should be fine, once you follow the steps above.
