Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
I was looking for the diagram because I haven't been under the car yet. Also I was looking for you to verify that it is the passenger side for me based on the code. I would also be looking for a replacement cat so a part number would help me. Can you help me with these things and any tips on replacing the part like special tools needed or heat applied for removal?
Yes that Cat is the passenger side, more than likely you will need some heat but in some cases you get lucky. This is a pretty tight job as in all the parts are in tight quarters, you are going to need a set of sockets and long extensions and wobbles to get in tight angles. Below is a diagram,
It appears the diagram is not working, give me a minute.
OK I got it through the link. It looks pretty simple to do. Should I replace both or just the one they said is not good?
Ok thanks. How about a part number for the cat replacement? Will I need to purchase anything other than the cat like gaskets or lubricant for the threads on the O2 sensors?
That was my next question. I would like to use the dealer part but I drive a lot and this car has 221900 miles on it. If aftermarket performance is ok to use than I would go that way to save the money. A suggestion of an aftermarket part would be helpful unless you think all aftermarkets are relatively equal.
Daryl, can you clarify the location of this cat again for me. I once replaced a cat on the drivers side in my driveway on my back that was a Bear. If I remember right, I removed a heat shield then discovered the cat reached the manifold and was not easy to maneuver around in these tight spots. Is this passengers cat in the same location just on the passengers side or is it another destination of cats further down the exhaust system toward the back of the car? I was thinking it is around the middle of the car and second to one closest to the manifold? Not opposite of the one i had replaced a year ago.
Thanks I was thinking that the resonator was what I needed to change based on the mechanics description. So now I know that this job is not as simple as a previously stated. However, I did do the drivers side myself last year. Do you think the passengers side will be more difficult for me to do? Also I have been looking online for replacement cats and came across re-certified OEM cats. What do you think about these. I have never heard of these before.
