Catalytic converters are in the exhaust system so replacing them is a job similar to replacing a muffler. Difference is that the converters are bolted in and have gaskets that must be replaced at the same time.
Apparently it has three. Two Pre-Catalytic converters right after the engine block, and a third after the y-junction and flex pipe. This is so the car meets the European emissions standards.
Catalytic converters are used to reduce emissions, however they only work at high temperatures, while they are warming up they do not reduce emissions, so the quicker they are functioning, the lower the emissions will be.
I have a 97 Impreza, and it should have 3 catalytic converters, but I took one off, and never put it back on, and my car runs just fine, so my answer is don't worry about it.
Its ability to get so hot the fibers from it are used n catalytic converters I buy them questions call nine three six 6720830
We have a 1993 Ford Bronco with 2 catalytic converters. Had one of the 2 replaced over a year and a half ago when we failed emissions. We passed with flying colors. So I say, it can be done.
In the old times the middle of a tooney fell out. so the government did something about it. So now if you find a broken tooney, keep it bacase it's valueble
The number of catalytic converters on a 2000 Chevy Astro van depends on the engine type and emission system configuration. The 2000 Chevy Astro van was available with two engine options: a 4.3-liter V6 engine or a 4.3-liter V6 engine with an extended range fuel tank. If the van has a standard 4.3-liter V6 engine, it would have one catalytic converter located in the exhaust system. If the van has an extended range fuel tank, it may have two catalytic converters, one located in the exhaust system before the fuel tank and another located after the fuel tank. However, it's important to note that the number of catalytic converters on a vehicle can also depend on regional emissions regulations and other factors, so it's always best to consult the vehicle's owner's manual or a qualified mechanic to confirm the number of catalytic converters on a specific vehicle.
There is Four(4) bolts on each catalytic converter. Your expedition has two cats installed. Removing these bolts may be difficult due to corrosion so take a grinder to them for a quick process.
