  • Keeping the Cylinder Head of Your Hummer H3 from Failing

    The Hummer H3 has a powerful engine specifically built to ensure its off-roading prowess. Unfortunately, no matter how great an engine is, it\'s still vulnerable to being damaged either from normal wearing out or from complications brought by its adjoining components. That is why utmost care should be given, not only to the engine itself but to the other parts as well such as the head gasket and the cylinder head.

    Several complaints have been made regarding the cylinder head of the H3 failing, and the best way to avoid this or to prevent it from happening again would be to correctly pinpoint what caused it in the first place.

    Cylinder head material

    On some circumstances, the blame on why the cylinder head has been failing was put on the cylinder head itself. The material it was made from was said to be not that durable and would mean a lot of repairing in the future. Hence, the only solution to the problem would be to replace it with a cylinder head made from better materials.

    A mixing of different types of metals, when it comes to engine parts, can also become problematic and could cause the cylinder head to crack, which would eventually lead to leaks. An example would be a solid cast iron engine block and an aluminum cylinder head under your hood. These two metals have different properties such as their tolerance to heat. They can expand at different rates, which would ultimately lead to the cylinder head cracking. So as much as possible, make sure that all engine components are made up of the same metal to avoid this type of problem.

    Thermal stress

    Heat is an already known enemy of vehicles, which either causes the metallic components to corrode or causes them to significantly wear out, or worse, totally break down. So what does the typical motorist do when the engine overheats? He soaks almost everything under the hood with water. Though that will obviously cool down the engine, it also has a downside to it. By immediately introducing water, the heated metal components will have no time to transition from having a high temperature to a lower one, which then causes thermal stress.

    Thermal stress weakens and wears out metallic engine components, such as your cylinder head, a lot faster than they normally should. This then could cause cracking and leaking. So the next time that your engine overheats, make sure that you don\'t immediately try to cool it down with water. Let it breathe for a while, and just give it some time to cool itself down. Not only would you be preventing your cylinder head to fail, but you would also be protecting the other components of your engine system from undue failure.

    Proper replacement

    If you\'ve ended up replacing your cylinder head, of course you would want it to be the first and the last time you\'re going to have to do it. And the key to achieve that would be to make sure that you do better maintenance and that the new cylinder head was correctly installed.

    Be sure that the correct parts, even the bolts, are being used. Because it doesn\'t matter how better you\'ve become at maintenance or that the new cylinder head is more durable, if it has been incorrectly placed or that wrong parts were used, then it would only be a matter of time before it fails as well.
