catalytic converter 防热板掉了

[方脑壳大爷]

请教各位，催化转换器的防热板（heat shield) 掉了，问dealer和CanadianTire, 有的说没事， 有的说冬天会将converter 冻暴，不知怎么办，换一个200$，是否值得？ 多谢！

Heat shield for Cat converter is mostly used to prevent heat entering passenger compartment. You will definitely fell the heat from Cat converter from the floor if without it. However, in winter time, it might be a plus. It will not affect your Cat converter.

Thank you.But the maintenance guy from the dealer said in winter, if you drive and splash cold icy water to cat converter, it may cause the cat converter explode, since it is very hot. So I feel a bit concerned over the winter? any idea? million thanks!

First of all, the heat shield there for reason when engineer design the vehicle. The guy at dealer could be right ( anything could happen ), but I think the way he explain it to you is bit serious. I do not know what kind of vehicle you have. Some cat is locate on the bottom of the car, and some is locate inside the engine bay area. No matter what, the heat shield will not cover the cat completely. Water, ice, stone etc can get in somehow. Assuming your car stuck in the snow, even the heat shield is there or not, the snow still touching the cat n caused whatever the dealer say. I will say it's better to have that replace since the vehicle has one when coming from the factory. Hope it's help.

you should get a heat wrap and warp up your cat converter. it reduces the tempurature a bit..I don't know if it helps if you afraid the heat will entering the passager compartment.

That will reduce the heat from the catalytic converter to cabin area BUT it will crack the catalytic converter because it will increase the interior temperature.
