Do not let the heat stop you from starting. Pro-long your starter's life and improve its performance. Our starter heat shields help prevent starter failure caused by overheating. Quality construction and design allow for easy installation. Simply wrap the heat shield cover around the starter and fasten with the hook and loop fasteners. Starter removal is not necessary in most cases. Two different sizes are available, therefore trimming is not necessary. Our heavy-duty cover is double- insulated to offer a greater reduction in radiant heat transfer. Our standard shields use aluminized cloth construction to reflect radiant heat away. Part# 501010 is designed specifically for small high torque starters. Investing a little now can save you time and money in the future!
