Peace be upon you and God's mercy and blessings. The starter insulator for the Caprice fits models from 2007 to 2016 with an 8-cylinder engine. It protects the starter from the heat of the exhaust, especially if the car takes a long time to start when it's hot. • Symptoms of damage or absence of the insulator: • The starter won't engage when the car is hot. • You need to wait for it to cool down. • You hear a clicking sound without starting.
