Catalytic converter


The exhaust downpipe is glowing red with heat?
To be honest, that may be fuel-air /and or cylinder head problem. A downpipe gets very hot, yes, but they don't glow red.

A faulty oxygen sensor can cause the catalytic converter to overheat - with disastrous results.

If you're not sure what you're doing don't mess around with things. get somebody who knows what they are doing to look at your car and give you an opinion

Why does my manifold turn red when I already changed the catalytic converter on my 2000 Toyota Avalon


Usually, a red manifold means that you have a lot of unburned fuel going into the exhaust stream. Most likely cause of this would be a cracked or warped exhaust valve or valve seat. A compression check of the engine cylinders can confirm a leaky valve quickly. Another possibility would be a blockage in the exhaust stream. Converters can break up and their parts can move through the exhaust and clog up the muffler. In theses cases, however, there is usually a significant loss of power on acceleration and often both the converter and exhaust manifold will get red hot.

The exhaust system could be blocked between the engine and the tail pipe. The fuel mixture could be too rich or too lean.

1994 Buick LeSabre does not want to take gas and exhaust manifold gets red hot


If you've checked your coolant and the gas is good it is likely the timing is off drastically and it needs fixed. I don't remember if that car has a chain or belt. I know most manufacturers change intervals on timing belts run from 60-90 thousand miles.Good luck those are nice cars when they are running well.

What cause my 2000 lexus es 300 exhaust manifold to get hot


The exhaust manifold is going to get hot, this is where the engines exhaust flows through. these tempertures reach high temps,

If the manifold is glowing hot then theres a problem.

Sometimes people say the manifolds are getting to hot because they see them smoking. The reason on most of these cases is due to a leak, aleak from a bad gasket like a valve cover gasket. Engine oil leaks down on to the exhaust manifold causing smoke. make sure there are no leaks .


A few reasons that would cause exhaust manifold to heat up more than normal would be a engine thats running rich, this may be due to a leaking injector or a poor running engine. Another reason may be that you have a plugged cat. converter.

The Exhaust manifolds can reach about 600 degrees, the last thing is people hear the metal expand or contract and think there are getting to hot , this is normal.

Please let me know if there is something else i can help you with. thank you and have a good day.

Red hot exhaust manifods


Make sure that your catalytic converter and exhaust is not plugged..Also check for propper map sensor operation,the reading that the map sensor supplies to the pcm is used to adjust ignition timing and fuel delivery.If the timing is being retarded to far , the exhaust exiting the cylinders will be extremly hot and will produce the effect you are having...Good Luck...
