When it comes to your car’s health, a head gasket is something you rarely think about. It’s a vital component that does not require maintenance and reminds you only when it goes bad and does not seal properly. This can lead to nasty scenarios, like coolant and oil mixing together, which can lead to catastrophic failure. The obvious solution is to replace it, which in some cases can be expensive. A viable alternative is to use a head gasket sealer. In order to save you the trouble, we’ve gathered some of the best products currently on offer.

Our last entry comes from K&W and features nanotechnology, for superior sealing capabilities. It creates a stronger bond allowing a virtually permanent sealing effect. In addition, this head gasket sealer does not come with any unwanted side effects like clogged radiators. It’s also offered in a 32-ounce (946 ml) package, which is more than many other head gasket repair solutions. All the product requires is a coolant flush before applying. Once this is done, it’s a simple pour-and-go. It’s good for both light vehicles and heavy-duty applications, such as trucks and buses. It’s specifically developed to seal cracked blocks or heads, as well as any leaks permanently.
Although there are a few universal solutions out there, it largely depends on your case.

Otherwise, ATP’s offer works as well, unless you’re working on transmission or power steering system.
