  Q: What is the purpose and maintenance requirements of the catalytic converter in a 1993-2011 Ford Ranger's exhaust system?

  A: The catalytic converter is an emission-control device in the exhaust system. It has a single-bed design with a three-way catalyst containing platinum and rhodium. This reduces NOx, HC, and CO. The system requires minimal maintenance but should be inspected during vehicle lift sessions or exhaust system checks. Check connections, clamps, and hangers for damage. Make sure the converter, metal protector plate, and heat insulator are intact. Functional checks involve diagnosing non-functional or restrictive converters causing low power or smog certification failures. Use a vacuum gauge and tachometer for a backpressure check. Steady high vacuum indicates a healthy system. If restricted, remove the exhaust pipe and replace the converter or exhaust Y-pipe, following safety measures and proper installation procedures.

  Q: What is the purpose and maintenance requirements of a catalytic converter on 2000-2011 Ford Ranger?

  A: The catalytic converter, an emission control device, needs occasional inspection for damage that could cause smog certification failure or low power. A backpressure test can identify a restricted converter. Replacement involves removing the exhaust system, installing a new converter with fresh gaskets and rubber hangers, and checking for leaks. For 4.0L V6 engines, the process includes replacing the exhaust Y-pipe, disconnecting the 02 sensor, and installing new gaskets and bolts.
