Timing issue - either cam or ignition.
It's lean.
Engine is running lean.
means you are running out of hot water
Glowing red indicates excessively lean mixture or timing is too far advanced. the exhaust ports opening too soon (most likely cause)
Lack of rain, rivers running dry and hot weather.
Resistors do that when there's a current running through them.
The exhaust pipe will turn red when the engine is running lean. You may have an EGR valve problem, vacuum leak or other problems that can cause the engine to run lean. A lean running engine can burn valves or pistons and causes other problems. Whatever the cause, it needs to be repaired before you put more miles on the engine, otherwise you'll ruin it, if you haven't already.
I dirt track race and mine did it once it was because it was running to lean.
The temperature of exhaust headers can reach 600 degrees. The temperature can be extremely dangerous. Working around hot exhaust headers requires caution.
you mean like overheating? could be a number of problems, radiator leak, radiator broke, radiator fan, leaky hose, broken water pump, broken head or head gasket, or the car running to lean.
If that's going on you might want to check for vacuum leaks and make sure the engine isn't running lean.
A/C compressor not running
