It's been reliable and we are very happy with it. Ill get back with everyone tomorrow, thats when I get the universal put in.Our 2001 Protege LX 2.0 has 76k miles and has served us extremely well. The only other thing I could think of is the coil packs. Ive replaced plugs and wires with original Mazda parts, as a part of normal maintenance. Protg kid, (or anyone else) if you have a moment, could you tell me the normal causes for cat failure? I assume something with the combustion of fuel (the reason for a converter). So, either my converter just went or there is an underlying cause. I asked if it was common for a cat to go, and what causes a cat converter to go and they said, sometimes they just go.

They pulled the same code (WOW) and I asked if there were any other codes, they said no, no other codes- nada. So instead of just putting in a cat converter I went to the professionals (say what you like) at a Mazda dealership to verify that it is in fact a catalytic converter. When the engine light first went on I took it to an auto parts store, and they pulled the code P0420 (they said most likely cat converter). The rest is just nuts and bolts from there to get the cat out. Now you can take a 7/8" or 22MM wrench and remove the O2 sensor from the exhaust manifold to get it out off the way. You can get the heat shield off by loosening the bolts, unplugging the O2 sensor then sliding the heat shield out of the engine compartment while the harness side of the O2 sensor is coming out the hole of the heat shield. You only really get one shot though because at that point the metal is so weak. I got it off by dremeling some of the metal off on six sides so I could step it down in socket size and get a good grip on it. One was so bad that it did round off loosening it. The bolts holding my heat shield on were fine, but the bolts on the bottom heat shield (under the car) were a little rough. I just had my cat out while I was replacing the exhaust manifold. You didn't mention if you had a ZM or FS. I will post my progress to the "how to" section of this forum, since other people will have this same problem in the future.
How do these stand up to Original Equipment? Which, after looking where the five bolts that attach the converter to the manifold seems like it might be the case.Īlso, there are a lot of aftermarket converters. The shop said that it is often easier to remove the whole manifold from the block with the converter attached and disassemble on the bench. So as a back up plan, if in fact I do shear off the bolts, I contacted a machine shop to see if the would be able to retap/clean out the threads in the manifold. I've been using PB blaster to no avail- and I don't want to shear the bolts off. They are corroded and pitted and the fit is sloppy on the socket. How do I remove/replace the converter and the manifold heat shield?īefore doing a repair I always look around to see where problems could arise before I do anything- well the bolts that attach the heat shield to the manifold seem to be the first problem. The check engine light went off- and the code was for the catalytic converter- verified by the mazda dealer.

I've got a 2000 protege that now has 158k repair free miles on it (ok the camshaft sensor went out last year- do 5 min repairs count?)
