Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / February 2007catalytic converter orientation
I bought a new aftermarket catalytic converter for an '85 Dodge B150 and I'm not sure how it fits... there is a little "L" shaped tube that comes off the body. I'm pretty sure it points foreward and on the top once it's installed, but not positive. I haven't found out much from searching the web, either. Welding it in won't be a problem, I just need to know which way it ges in. Does anyone know for sure? > I bought a new aftermarket catalytic converter for an '85 Dodge B150 > and I'm not sure how it fits... there is a little "L" shaped tube that > comes off the body. Air intake from the smog pump. Did your old converter have one? Is there an air pipe from the pump? > I'm pretty sure it points foreward and on the top once it's installed, > but not positive. I haven't found out much from searching the web, either. Rockauto has various pics, depending on whether it's a 6 or 8-cyl. None of them show an air inlet, but they all show the converter having a short pipe in front, and a longer pipe behind, angling to the passenger side. Here's Walker's diagrams: 6-cyl http://www.walkerexhaust.com/images/coupons/2618.gif 8-cyl http://www.walkerexhaust.com/images/coupons/2619.gif And Merit's: 6-cyl http://www.goerlichs.com/customers/app_catalog/app_images/23523.jpg 8-cyl http://www.goerlichs.com/customers/app_catalog/app_images/24698.jpg > > I bought a new aftermarket catalytic converter for an '85 Dodge B150 > > and I'm not sure how it fits... there is a little "L" shaped tube that [quoted text clipped - 6 lines] > > I'm pretty sure it points foreward and on the top once it's installed, > > but not positive. I haven't found out much from searching the web, either. Thanks for the help! There is a long tube that used to run to the old cat converter. I think it is an air pump, to blow a little air in so the converter has oxygen to do the job. The "L" tube on the new converter doesn't have any fittings on it to match the air tube running from the engine, so I'll just need to weld on a fitting or something. I've heard you can run the after-market converters without pumping air into it, but I'd like to hook up the air blower tube anyways. I ended up mounting the converter so the tube points forward, but is on the bottom so I can add the correct fitting.

On my Ford I used a Walker #35574 "AIR tube kit" that comes with a short steel tube and a dual-sized high temperature hose that you cut-to-fit to connect the old pipe to the converter's inlet. Here's the only pic I could find.... http://napaonline.com/masterpages/NOLMaster.aspx?PageId=470&LineCode=EXH&PartNum ber=35574&Description=Catalytic > On my Ford I used a Walker #35574 "AIR tube kit" that comes with a short > steel tube and a dual-sized high temperature hose that you cut-to-fit to connect [quoted text clipped - 3 lines] > > http://napaonline.com/masterpages/NOLMaster.aspx?PageId=470&LineCode=... Thanks -- I didn't know there was such a thing! I'll go by the nearest NAPA tonight and pick one up. > On my Ford I used a Walker #35574 "AIR tube kit" that comes with a short > steel tube and a dual-sized high temperature hose that you cut-to-fit to connect [quoted text clipped - 3 lines] > > http://napaonline.com/masterpages/NOLMaster.aspx?PageId=470&LineCode=... Yikes! I called and they want over $30 for that thing. Does that seem high? It's basically a rubber tube and some hose clamps... Do you know anyone else who sells the same thing for less? > <jpola...@rgs.uci.edu> wrote > [quoted text clipped - 15 lines] > > http://napaonline.com/masterpages/NOLMaster.aspx?PageId=470&LineCode=... Just to follow up on this -- I ended up buying the Walker #35574 "Air tube kit" from Napa and it worked fine. Thanks for the pointer! |
