What causes the exhaust manifolds to glow red?
July 5, 2016, 8:18pm #5. Often this is caused by a clogged or partially clogged catalytic converter. This could be tested very easily with a vacuum gauge.

I have a 2004 Pontiac Grand Prix with the 3.8l supercharged engine. The car has been running hot so I drove it up a mountain road to get it hot and see if the fans were coming on (they were). When I opened the hood to check the fans I noticed that the exhaust manifolds were glowing red.

Why are the exhaust pipes on my Triumph Bonneville glowing?
Glowing exhausts are neat, install windows in your hood to show them off. My motorbike (Triumph Bonneville) has glowing pipes. On that it is caused by the air injection system putting air into the exhaust at the exhaust valve location to burn off any unburnt hydrocarbons. No Cat converter.

Why does my Honda Civic idle too high?
When cold you just get an idle that is too high like up around the 1200-1500rpm range or higher. The second video shows a vacuum leak that I found on a Civic using a ‘safer’ method for checking for vacuum leaks. Both work but the important thing is that you check for vacuum leaks if you have a Honda idle problem.

Can a red hot exhaust manifold start a fire?
ANY red hot ANYTHING under your hood is going to start a fire, sooner or later. I’d bet on sooner. And of course, even without the car burning to a crisp, you’re polluting the air. If it was mine, I’d get it fixed today. ok4450 July 5, 2016, 8:18pm #5 Often this is caused by a clogged or partially clogged catalytic converter.
