| Is there a trick to getting these things loose? I need to replace it but it is seized in. |
|
As others have said, hit it with a spray lubricant while it is hot.
The trick is to keep applying the lubricant (I use WD-40) until it stops smoking. As it cools from being quinched, it will suck the lubricant into the nooks and crannies. Then just use a big wrench. |
Would probably work fine on a stock exhaust, though.|
Quoted:
Drive around for a while, park the car for about 10-15 minutes, spray some Liquid Wrench or PB Blaster (WD-40 probably won't do anything), give that 3-4 minutes to seep in, then put a box-end wrench on and beat the shit out of it. Here you go. Once you break it loose work it back and forth so the threads don't sieze back up. |

Just curious: Why are you replacing it? I think I have to replace the Catalytic Converter. I'm not sure if the O2 sensor has to come out when I change the CAT. I have a P0420 code, Found the pipe into the converter was loose. I fixed that cleared the code. The light came back on today with the same code. I'm deciding whether the attempt changing the CAT myself of paying a garage to do it. Car is due for inspection this month so I can't wait too long. |
