I have fuel going into bank 1 cat

Question

Just replaced cat on bank 1 and it looks orangy in color why.

Answer 1

Orange in color you can get this from fuel injector cleaner additive, if you are your sparkplug would have the orange tinge, Be also aware that Jeep uses Mopar anti freeze formula HOAT which is orange in color , If there is coolant seepage you can be sure you will replace the catalytic convertor again. It  is not going to hurt if you add a small amount of radiator stop leak, Most vehicle after 2007 adds a small amount of stop leak, For example GM product add a pellet in there cooling system to help seal the intake manifold after a water replacement or anything with the coolant system service or repair and  recommends their pellet be added again.(this the rusty looking thing in there cooling system)
