How to Replace a 2000 Firebird Catalytic Converter

Replacing the catalytic converter on your Firebird can improve fuel economy, engine performance and drivability. Catalytic converters are not prone to failure but when they do go bad, they will run very hot and can choke off the flow of exhaust from the engine. Replacement converters are available from several sources including automotive parts stores or the dealers parts department. Some salvage yards or parts recyclers also stock good used converters at discounted prices.

Instructions

1

Raise the front of the car with a jack and position a set of jack stands under the frame to support the car. Locate the catalytic converter under the passengers side of the car.

2

Remove the retaining bolt on the exhaust clamp at the rear of the catalytic converter with a wrench. Move to the front of the converter and remove the four bolts from the mounting flange between the front of the converter and the exhaust pipe with a socket and ratchet.

3

Lower the converter down and move it out from under the car. Discard the old converter.

4

Position the new converter under the car and raise it up into position. Slide a new gasket in between the front flange on the exhaust pipe and the flange on the converter. Install the four mounting bolts and tighten them with a socket and ratchet.

5

Install the exhaust clamp on the rear of the converter and tighten the retaining bolt with a wrench or socket and ratchet. Do not over tighten the bolts; the pipe will deform causing an exhaust leak if this bolt is too tight.

6

Raise the front of the car off the jack stands with a jack. Remove the stands from under the front of the car and lower the jack.
