Default 1997 K1500 DIY Catalytic Converter

My service engine light is on and the dealer says I need a new Converter and a few other sensors. Does anyone have a DIY listing for this?

Thanks,

Mark

We could help you with the converter, but you need to tell us a little more than "a few other sensors" if you want help with that.

What is the code #? If you have a converter efficiency code only, all you need is the cat. I bet they are pushing O2 sensors.

Default Got more info

Hey guys,

Thanks for the reply, I have more info directly from the dealer. I was quoted $1800 to replace CAT Converter, a seal (I assume to the converter) X2, a gasket and three sensors. Part numbers are as follows:

15093974 SEAL Where does this get installed?
15746547 CAT CONVERTER " "
15051878 GASKET " "
19178116 OXYGEN SENSOR " "
19178934 SENSOR " "
25312191 SENSOR " "

This job does not seem very labor intensive due to the dealer part pricing is $1510.39. If I can find the parts online cheaper(I am sure I can) and you guys could help me with the DIY labor, I am on my way to saving big bucks!!!

Please help

There is really no special knowledge needed to replace parts in an exhaust system other than skill in removing rusted bolts. An independent exhaust shop may be able to give you a lot better price than the dealer. If you do it yourself, all you will really need is hand tools and a torch to heat up stuck bolts. However, an impact wrench would be handy.

Check gmpartsdirect.com with the part numbers you have and compare to the dealer part price.

Oxygen sensors generally go into the exhaust pipe similar to a spark plug. Screw it in and plug it into the harness. The other sensors are only listed as "Computer Sensors" in GMPartsDirect. I don't know where they go or how they are installed.

Vester is right, the last 2 sensors are listed as computer sensors. They may also mount in the cat, it list having 3 sensor locations. If you but the parts direct and take a look at them you should be able to match them up. If not then post some pics of them and we can help you with it.

I doubt all the O2 sensors are bad. Get the converter and put it on your self. Easy job just take the bolts out. Wait and see if any codes return.
