Controlling Under Hood Temperature With Heat Wraps

Today’s engine compartments typically do not have a lot of space and heat coming from exhaust manifolds and headers can quickly cause under-hood temperatures to reach extremely high temperatures. One way to dramatically reduce engine compartment heat is by using a durable heat wrap.

There are two common kinds of heat wrap rolls available to automotive enthusiasts for installation on their exhaust manifolds and headers. The lease costly heat wrap is designed from glass fiber and has the lowest thermal rating of all wraps. The more popular heat wrap products installed are created from pulverized lava rock and are superior to wraps made with glass fiber.

The installation of glass fiber heat wrap is more complex then those which are made from pulverized lava rock. Glass fiber heat wrap roll typically must be applied while wet to adapt to tight bends, which are typical with exhaust manifolds and headers. Additionally, glass fiber wraps also must have a protective silicone coating over the finished wrap. With pulverized lava heat wraps, there is no reason to wet the wrap for application and no need for a finish silicone coating.

Regardless of which heat wrap roll is installed on an exhaust manifold or header, they must be installed with one-quarter of an inch overlaps. The goal is to contain most of the heat, but not all of it. The wraps must be properly secured with stainless steel ties where the wrap begins and where it terminates.

After a vehicle is started, following the installation of heat wraps, it is normal for the heat wraps to smoke as the engine comes up to normal operating temperature. This is common and typically stops after an hour or two of use. During this period of time it is advised to close up the windows and close any vents in the vehicle.

With an adequately applied heat wrap, the under-hood temperature drop can reach 50%. Heat wraps manufactured from pulverized lava rock will achieve the best reduction in temperature. Automotive enthusiasts interested in reducing the engine compartment temperature the most will find pulverized lava heat wraps to be the better choice.

Automotive enthusiasts wanting to protect select engine components can also benefit from improved thermal protection for components. Whether it is a turbo, starter or even a battery, these engine components can also be wrapped to reduce their exposure to heat even more.

In addition to automotive applications, heat wraps also have industrial and commercial uses. Such applications may include shielding pipes or stacks to limit human exposure to intense heat. Whatever the application is, modern day heat wraps have been proven to restrict heat and do provide useful thermal protection.

Those interested in reducing their engine compartment temperatures will find Justin Smith’s knowledge of automotive exhaust Uk marriage visa heat wrap rolls useful. Justin has helped thousands of vehicle owners wrap their exhaust manifolds and headers for improved engine performance.
