The catalytic converter installed in your Ford Expedition is more than just a simple car part; it's a device that minimizes the smoke emission before it's released in the atmosphere. If your car already produces visible smoke along with a foul smell from the exhaust, then this could be a symptom of a bad catalytic converter. An even worse situation is when the catalytic converter burns the ceramic monolith inside it because the fuel is stuck and couldn't reach the engine. To solve this problem, you have to find a new catalytic converter before authorities notice the thick smoke behind your vehicle and pull you over.

Frequently Asked Questions

Ask APW
  • Does soap and water actually clean a greasy Ford Expedition catalytic converter?
    Answer: A more precise answer to that is a dish detergent and water. Since a dish detergent is very effective when it comes to removing grease and oil, then it's a very good cleaning agent for a catalytic converter. The only thing that needs to be done is to dip the catalytic converter in a bucket with water and dish detergent overnight. As a reminder, never put a lacquer thinner when cleaning a catalytic converter for a diesel fuel.
  • In a Ford Expedition with a V8 5.4 liter engine, should all four catalytic converter be replaced at the same time?
    Answer: It will depend on the condition of each catalytic converter. If there's a need to replace all because they're already clogged, then look for four replacements. Although it is very unlikely that clogging happens simultaneously.
  • What are ways to prevent a stolen catalytic converter in a Ford Expedition that's always parked around a tough neighborhood?
    Answer: If the catalytic converter under the Ford Expedition is a bolt-on type, then to weld the bolts shut is a good idea. Another way is to clamp the catalytic converter, or to fence the parking area to slow the thief down. Add security lighting on top of the car to make it visible at night. This can also slow down or prevent the thief because the suspension of a Ford Expedition is usually higher than a regular vehicle that's why it's an easy target.
  • Which is better for a Ford Expedition, a 49-state and a 50-state catalytic converter?
    Answer: A 49-state catalytic converter basically means that the California Air Resources Board has not approved or tested a particular catalytic converter. To give a brief overview, the state of California has the following additional laws regarding catalytic converters: one, only brand new catalytic converters are allowed to be sold in the state; and two, they have to be approved by CARB and before they're used. It does nothing with the performance of the Ford Expedition, but with the regulations it must follow.
