No, a catalytic converter typically does not cause a car to overheat. However, if the catalytic converter is damaged or malfunctioning, it can potentially cause the car to run hotter than normal. This can occur if the internal structure of the converter becomes clogged or blocked, restricting the flow of exhaust gases and causing the engine to work harder to push them out.
Additionally, if the catalytic converter has overheated in the past, it can become less efficient and generate more heat than it should, further contributing to potential overheating issues in the car.
