Let’s say you are working on your Nissan Frontier, for example, and decide that you want to change the exhaust headers. One of the most challenging parts of this process is getting the right seal between the headers and the engine block. Any time you are dealing with precision-engineered auto parts, you will see information on “torque specifications.” What are these? What do they have to do with Nissan Frontier auto parts?
What Are They?
Torque is a rotational force. The most common reasons you will hear about torque related to the engine’s ability to rotate the driveshaft and ultimately move the wheels.
However, everything that is rotated is affected by torque. When you tighten a bolt, you are imparting torque on the bolt head using your wrench. This is where torque specifications come into the conversation.
Although the bolts in your engine are very strong, they are still slightly elastic (they can stretch and deform). Having a really strong hold is important for the hardware using on vehicle components. Therefore, when you are tightening bolts in the engine (and some other high-importance parts), they need to be rotated to the perfect amount of torque using a special tool called a torque wrench.
In most cases, torque specifications involve tightening to a certain amount of torque, loosening the bolt then tightening it again. Torque is usually measured in foot-pounds (imperial) or newton-meters (metric). Torque specs sometimes also include a rotation figure, often as the final spec, measured in degrees.
Why Are Torque Specifications Important?
As mentioned briefly above, the reasons that torque specifications are important because achieving a perfect seal is important for vehicle components, especially those that deal with increased pressures such as the intake manifold. Avoiding deformation of the bolts helps to make the seal stronger and smoother.
So, if you are working on your Frontier, you will need to pick up the right Nissan Frontier torque specifications before you start. It is a must to ensure the success of the project.
Where To Find Torque Specifications
You can find the torque specifications for your vehicle in the service manual. This is produced by your manufacturer to provide mechanics with all the details they need to work on your car or truck. It can be a great resource for both troubleshooting issues and fixing them. If you are serious about working on your car or truck yourself, this is a must-have item.
Another option is to check the internet. Many brands such as AutoZone have information on everything from torque specs to brake pad replacement details. The more you learn about how to work on your vehicle, the more comfortable you will become and the more projects you can take on, even challenging ones.
