Heat shields are an important tool for car owners, as they protect vehicle's interior from intense heat of exhaust pipe. Heat shields also help to prevent engine and other vital components from overheating due to hot exhaust. If you’re looking to make your own heat shield, here’s a step-by-step guide on making a DIY heat shield.

Step 1: Measure and Cut

The first step is to measure and cut material for your heat shield. Common materials used for homemade shields include steel, aluminum, and high-temperature plastics such as Nomex or polyethylene. The highest quality heat shields are made from stainless steel and are highly resistant to heat and corrosion. When measuring for your shield, be sure to leave enough room to cover entire exhaust area.

Step 2: Form and Attach

After measuring and cutting material, next step is to form shield into desired shape. This can be done by either bending material or cutting it into desired shape. Once shield is formed, next step is to attach it to exhaust pipe. This can be done using screws and bolts, or by using specialized high-temperature adhesive.

Step 3: Finishing Touches

Once heat shield is attached, it’s time to add finishing touches. This may include painting shield or adding a protective coating to ensure it is able to withstand extreme temperatures. It is important to use a paint or coating that is designed to withstand heat of exhaust. Once paint or coating is dry, heat shield is ready to be installed.

Heat shields are an important tool for ensuring that vehicle's components are not damaged by intense heat of exhaust system. Making your own heat shield is relatively straightforward, and can save you a considerable amount of money over buying a pre-made shield. Just remember to take necessary safety precautions when working with hot exhausts, and to use high-quality materials to ensure your DIY heat shield is of highest quality.
