Summer is here, which means fun times cruising, going to car shows and/or off-roading. But along with sunny skies and great scenery comes heat. Controlling the heat that your car or truck makes with the right heat shields can avoid overheating, vapor lock and keep you a lot cooler and more comfortable inside your ride.


We’ve put together a list of thermal-barrier products from Heatshield that can keep the heat at bay and your ride running properly.


Thermaflect Sleeve


ABOVE: Thermaflect Sleeve™ is great for fuel lines as well as for protecting power-steering lines, brake lines, wiring bundles and harnesses, and even radiator hoses. It can withstand constant radiant heat up to 1,100 degrees Fahrenheit, intermittent radiant heat up to 2,000 degrees and up to 500 degrees of direct heat.


If you have a carbureted vehicle, you know that vapor lock is a potential summertime issue. Gasoline heats up in the fuel line, turning into a vapor, and stopping the flow of fuel to the carburetor.


Thermaflect Sleeve™ is a thermal-barrier sleeve that deflects up to 90 percent of the heat that can heat up fuel lines. It comes in multiple diameters, in either a pre-sewn sleeve or with built-in high-temperature, hook-and-loop fastener material for easy installation and removal. Its silver, reflective finish gives a positive aesthetic quality that won’t hurt the look of any engine compartment.


HP Starter Shield



ABOVE: HP Starter Shield comes in three different sizes, covering most starters in the domestic and foreign market .


If you’ve got a vehicle with headers, you’ve probably experienced that moment when instead of hearing the starter engage, all you hear is the dreaded starter death click. Sometimes you might be lucky enough that when you hit it with a hammer or blunt object a couple times, it frees up, but eventually it won’t work anymore, even if you hit it with Mjölnir. A starter can only take heat soaking so many times before it develops high spots and/or the solenoid gets cooked permanently.


HP Starter Shield is the quick and easy way to keep your starter working perfectly when the hot summer heat adds to the ambient heat already under the hood. It can handle constant heat of up to 1,100 degrees, and up to 2,000 degrees of intermittent heat. Its built-in, high-temperature, hook-and-loop fastener system makes installation quick and easy, even with the starter installed on the engine. And if you need to change starters for some reason, you can reinstall the HP Starter Shield on the new one.



Heatshield Armor


ABOVE: Heatshield Armor™ comes in precut sheets with either ¼ or ½ inch thickness. It can be trimmed and easily shaped to fit both straight and curved pipes and is a simple installation with Heatshield Products Thermal-Ties™. And if the Heatshield Armor™ gets wet from driving in the rain, it won’t fall apart or stop working.


Heat from the exhaust system can cause multiple problems during the dog days of summer. Anything mounted near the exhaust is subject to excessive ambient heat, and those heat shields installed at the factory are marginally effective (at best) in deflecting heat from components. If you’re in a classic car/truck that doesn’t have air conditioning, all that ambient heat generated by the exhaust rises up to soak the floor pans of the vehicle, which can heat up the interior like an oven and make the ride miserable.


Heatshield Armor™ utilizes a specially formulated and designed BioCool™ thermal-barrier material made by Heatshield Products, so it keeps all the heat where it belongs: inside your exhaust system. This drastically reduces the amount of heat being radiated under the vehicle and the heat exposure to peripheral components. An added benefit of keeping all the heat in the exhaust system is that it raises the exhaust gas temperature (EGT), which in turn increases exhaust gas velocity and improves performance. It can handle up to 1,800 degrees Fahrenheit of constant heat, and up to 2,200 degrees of intermittent heat.



HP Sticky Shield


ABOVE: HP Sticky Shield™ is also a great multipurpose thermal barrier insulation that you can stick just about anywhere to help protect components from ambient heat, including the underside of the transmission tunnel and floor to shield them from ambient heat that can get inside your vehicle.


Earlier, we mentioned vapor lock and protecting fuel lines from being heated. But there’s another part of the equation in preventing vapor lock that often gets overlooked: the gas tank.


If your ride has a metal gas tank, it can be heated by ambient heat, and that will heat the fuel inside. Shielding only your exhaust may not fully get the job done, because there’s an even bigger ambient heat source right below your tank that you can’t shield—the concrete or asphalt the vehicle is parked on or driving over. The heat will radiate upward, soak into the tank, then, eventually, heat the fuel.


With its built-in adhesive backing and BioCool™ thermal-barrier material, HP Sticky Shield™ is a great way to deflect up to 90 percent of radiant heat. It can handle 1,100 degrees of constant ambient heat and 2,200 degrees intermittent ambient heat, keeping the tank as cool as possible.
