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.
