When a car's bellows fail, it can cause a number of problems. The most common problem is that the car will not start. This is because the bellows are responsible for pumping air into the engine. Without them, the engine will not have enough air to run properly.
Another problem that can occur is that the car will stall. This is because the bellows are also responsible for keeping the engine cool. Without them, the engine will overheat and eventually stall.
Lastly, bellows failure can cause damage to other parts of the car. This is because when they fail, they often leak oil or coolant. These fluids can damage other parts of the car if they leak onto them.
