What else can I help you with?
Why does the exhaust manifolds on your 2000 E250 4.2 get red hot?
Normally a blocked catalytic converter or a blocked exhaust will cause that problem. Back pressure, means the gasses cannot escape. thus causing the manifolds to glow.
How do you know if the Intake gasket leaks on 1987 Pontiac fiero?
The engine runs fast, won't idle down, and many times the exhaust manifolds will glow red hot from the lean mixture.
What would cause exhaust manifolds to get orangish red hot on 94 Toyota 4 runner?
Plugged converter possibly or other exhaust restriction. exhaust is very very hot, because of this, your exaust manifolds/headers are going to get very very hot, especially if you tend to run high RPMs. if everything else like throttle response is fine, i wouldn't worry
Can Motor oil caked on the manifold catch fire?
Exhaust manifolds get very hot, it is possible but not a common occurance
Why does the exhaust manifold glow red hot?
Advanced timing can cause that to happen
Why does header glow red on your sv650s?
The exhaust gasses pass though there, and they're really hot.
What are the functions ofengine inlet and exhaust manifolds?
Inlet manifolds are actually called intake manifold and this is to allow air to be injected into the fuel for either a rich or lean mixture for either performance or gas mileage (which can be adjusted). The Exhaust manifold is used to expel your burnt fuel, or air/fuel mixture, during the exhaust stroke on a 4-cycle engine to allow room for the intake stroke to bring in your fuel, or air/fuel mixture. The exhaust manifold simply directs the exhaust and become extremely hot. The exhaust is pushed out by the exhaust stroke.
What causes flames to come out of NASCAR tire area?
When the driver let's off the gas pedal going into a turn raw fuel gets pumped into the exhaust manifold. The manifold is so hot the fuel ignites and you see flames from the exhaust pipe. It's totally normal.
What makes the exhaust manifold get red hot on a 1985 Chevy Suburban with a 350 throttle body?
The exhaust manifolds on a normal, properly tuned vehicle engine WILL NOT overheat to the point they glow unless you have a turbo setup. If this happens you have improper fuel mixture or the timing is off. Even a turbo setup should only have a small bit of orange glow and that's only if you're running the engine hard.

How hot are green flames compared to other colored flames?
Green flames are typically not as hot as blue flames, but are hotter than red or orange flames.
What would cause the exhaust manifold of a 91 Nissan Stanza 4 cylinder to glow red hot with or without the converter?
The fuel mixtue has gone lean.
What causes a 1998 Chevy Tahoe not to try to turn over but if it sits for a few minutes it is fine when the battery is OK and all electronics come on?
Exhaust is overheating the starter, starter may be going bad or exhaust could be starting to plug up and getting to hot near manifolds
