Can you replace the heat shield on a catalytic converter?
The heat shield keeps your car from either catching fire or setting something else on fire if your catalytic converter overheats. Catalytic converters run very hot. A red-hot converter could also set fire to something underneath the car, like some grass or leaves you park over. So we do recommend you replace it.
Why is my catalytic converter rattling?
Rattling noises are another symptom of a bad or failing catalytic converter. If a catalytic converter becomes old or damaged internally from excessively rich fuel mixtures, the catalyst coated honeycomb meshes on the inside of the converter can collapse or break apart, causing a rattle.
How does a catalytic converter heat shield work?
A muffler and catalytic converter heat shield can reduce interior temperatures and protect nearby components. Heatshield Products Muffler Armor™ uses our BioCool thermal-barrier material to withstand 1,800 degrees F of continuous heat, which helps reduce radiant heat from mufflers by up to 70 percent.
Is the heat shield on the new cat?
Yes the new cat does have welded heat shield on, BUT it is pointed down instead of up at the car body. And the welded-on heat shield is pointless IMO. Looks like I will have to be without the heat shield.
Where is the catalytic converter under the car?
Budd2049, this catalytic converter is under the hood, not under the car, so the carpet won’t catch fire, but the hood might heat to the point where the paint burns off or bubbles and peels.
Can a catalytic converter cause a car to catch on fire?
Rule of thumb: If the manufacturer put it in, it’s needed. Not only can the catalytic converter’s heat warm up the interior of the car, it can cause a fire if you park on dry grass or leaves. As to whether the mechanic removed it – it’s not really for us to say – you’d have to know if it was there before you brought it in. But I’d be suspicious.
