Introduction
Go to step 1 ↓This guide demonstrates how to replace the fan belt on a Chevy Corvair. The belt gets worn down easily due to its placement and because it's used for an air-cooled engine. It is very common for the belt to become damaged or torn, so regular maintenance is necessary.
Before you begin this repair, make sure the car is turned off, parked, and that the engine has cooled if you recently drove it.
