How to fix a blown head gasket without replacing it?
Automotive experts understand the challenge of dealing with a blown head gasket. They know exactly how much it costs and how critical it is to get the head gasket fixed before needing to replace it.
That's why they decided to put together a step-by-step process to help you how to fix a blown head gasket without replacing it. Let's take a closer look below:
1. Step #1: Locate the source of the leak
The first step in fixing your head gasket without needing to install it is to locate the leak's location. As we indicated earlier, most head gasket problems are linked to some holes or damages in the weak seals around the head gasket.
You can perform a quick visual inspection and look at the engine to see where the cooling is dripping. Sometimes you might not see actual fluid dripping, but you'll notice that the area is wet compared to the rest of the head gasket and the engine.
2. Step #2: Clean the area around the leak
Since we'll help you understand how to fix a head gasket without replacing it by adding some sealants, it's important to start cleaning a new area. Typically, the sealants will only work if the area is clean and there's a lot of contamination.
This clean-up process is essential because it helps the sealant adhere properly to the head gasket surface and does its job properly without causing any trouble.
3. Step #3: drain the coolant from the engine
Once the area is cleaned, the next step is to take care of any coolant in the engine. In other words, you have to drain the engine coolant outside by simply opening the drain plug underneath the reservoir.
It would be best if you had a tray or bucket to collect all the coolant because it's contaminated, which might contaminate the area around the vehicle. Thus, you need to place this bucket underneath the location of the drain before you even open it.
4. Step #4: remove any debris or buildup
In some instances, there might be some debris or contaminants collected around the head gasket. You can remove those by using a wire brush or gasket scraper. It's important to clean all these because they might prevent the sealant from adhering properly to the head gasket surface if they're still there.
5. Step #5: Apply the sealant
There are many examples of sealants you can use to fix the head gasket without needing to replace it. That's why we encourage you to go through each of their main pros and cons to make sure that you are purchasing the right one that works for you.
On the sealant package, you should find detailed instructions about how to apply it. Follow these instructions and add the required sealant to the leak's location.
6. Step #6: allow the sealant to dry
Most sealants designed specifically for fixing head gasket problems are designed in a way that needs to be dried. That's why we still recommend allowing the sealant to cool down and dry for the time specified on the package.
Failing to do so can lead to some troubles and prevent successful results. Therefore, it's important that you be as patient as possible to get what you're looking for and to avoid further complications.
7. Step #7: reinstall the drain plug
Once the sealant is dry, the next step is to install the drain plug. Again, you need to ensure that you're installing the drain plug properly without over-tightening it because this could cause some trouble the next time you perform a coolant replacement.
You should find instructions about how much you can tighten the drain plug without damaging it or causing further complications on the vehicle owner's manual. You can also check online for some recommendations with tools and videos.
8. Step #8: start the engine and check for leaks
Finally, once you are done tightening the drain plug, you need to add the required coolant and check if the engine is still suffering from a coolant leak. You can allow the engine to run for some time and keep an eye on the vehicle to check for any signs of fluid dripping.
If you feel the problem still exists, you should repeat the process or consult your mechanic, especially if the leak is very severe.

2. Cylinder head resurfacing

During this process, you will need to use a specific machine that helps smooth out the top portion of the cylinder head and allows it to connect securely to the head gasket without any potential leaks.
As you might notice, this problem and this procedure require certain tools and skills. Therefore, it'd be best to leave it to professionals rather than trying to fix it yourself because this could introduce problems with the engine beyond what you can afford.
3. Cylinder head replacement
Finally, in more complicated scenarios, resurface the head of the caskets in our work. Therefore, some mechanics might go the route of replacing the whole head gasket instead. This is still a significant repair, but it's cheaper than going there. So I was off replacing the whole head gasket.
