Lava Tube - Heat shield sleeve with carbon fiber look.Hot Rod Sleeve - Prevent fuel system vapor lock and shield wires from heat.Some products have versions with built-in, high-temperature hook & loop fastening systems for easy installation and removal. Heatshield Products offers multiple types of heat shield sleeves along with its lineup of other insulation and thermal barrier materials. And everything is made in the USA from the highest quality components. The engine wire protection will also shield the wiring from direct contact damage from a heat source if a fastener holding the harness in place fails.įor the best heat shield sleeves and insulation materials, Heatshield Products is the number one source for the most effective thermal barriers. Less heat exposure helps extend the lifespan of the wiring, improve reliability, and make it easier to maintain the vehicle. Invest in a USA-Made Heat Shield for Engine WiresĪdding a high-temperature heat shield sleeve to your vehicle’s wiring harness will help reduce the risk of the aforementioned issues, if not eliminate them outright. Without proper insulation to protect the wiring from heat exposure, it will begin to degrade until it partially fails (intermittent, unreliable component function), completely fails (internal breakage of copper fibers), or creates a short circuit situation that leads to a fire hazard. Besides having a computer to control the engine and drivetrain, many cars today have separate computers that manage the function of the interior systems, the chassis, and, in some cases, a separate ECU for the transmission.Īll of this adds even more wiring to a vehicle, and with today’s engines designed to run constantly at temperatures 200 degrees F or higher, the wiring is constantly exposed to a lot of heat. Besides powering various components, the wiring also receives signals from the vehicle’s ECU, which controls components and collects data to keep a vehicle running at optimum levels. Multiple systems inside a modern vehicle rely upon wiring for power and electronic control: the engine, transmission, chassis, interior, and body. Why It’s Important to Protect Wires from Engine Heat A single overheated or melted wire can get you stuck on the side of the road, helpless in many of today’s cars and trucks. An engine bay has miles of essential wires controlling things like headlights, wipers, air conditioning, brakes, and more.Ĭonstantly heated/overheated wiring can lead to partial function of components, malfunction of sensors, and even short circuits from melted wiring, leading to fire. The heat exposure also increases the electrical resistance of the wiring, which can also negatively affect the function of sensors, electric components, and engine operation. As wiring is subjected to constant high heat, the wiring can degrade over time physically and lead to electrical problems. It’s crucial to pick the right heat shield sleeve for engine bay wiring to protect wires from engine heat. It needs to be a material built specifically for underhood automotive applications and withstand constant temperatures up to 125☌, or 257☏. The answer is simple: install insulating engine wire protection or heat shield sleeve material that can withstand direct contact with high-temperature surfaces and is flameproof. It’s unavoidable, but it raises a valid concern - how do you protect wires from constant engine heat exposure and direct contact with high heat sources? In this article, we’ll discuss how to protect wires from engine heat.

The more you drive your car, the more frequently the engine will heat cycle from “cold” to operating temperature. Safeguarding Your Vehicle with Heat Shield Engine Wire Protection
