* Overheating Engine: This is the most serious possibility. An overheating engine can cause the exhaust manifold to glow red hot due to excessive heat. Check your coolant level, look for leaks, and ensure your cooling system (radiator, water pump, thermostat, etc.) is functioning correctly.
* Lean Air/Fuel Mixture: A lean mixture (too much air, not enough fuel) burns hotter, leading to increased exhaust temperatures. This could be due to a faulty oxygen sensor, mass airflow sensor (MAF), fuel injectors, or a problem with the fuel pump or fuel delivery system.
* Ignition Problems: Misfiring cylinders can cause increased exhaust temperatures in the affected cylinder's exhaust manifold. This could be due to faulty spark plugs, wires, ignition coil, or distributor (if applicable).
* Restricted Exhaust System: A clogged catalytic converter or muffler can restrict exhaust flow, causing higher manifold temperatures. Look for any obstructions in the exhaust system.
* Exhaust Leak Before Manifold: While less likely to cause the *manifold* to glow red hot, a leak before the manifold could cause higher temperatures in that area.
* Driving Conditions: Sustained high RPM driving, especially under heavy load (towing, prolonged uphill driving), can generate high exhaust temperatures, but this usually wouldn't lead to a *glowing* red hot manifold unless another problem is present.
What to do:
1. Do NOT touch the exhaust manifold. It's extremely hot and you can severely burn yourself.
2. Turn off the engine immediately. Continued operation could cause serious engine damage.
3. Let the engine cool completely before attempting any inspection or repairs.
4. Check your coolant level. Look for any signs of leaks.
5. Inspect the exhaust system for any blockages or leaks.
6. If you're not mechanically inclined, take your Camaro to a qualified mechanic immediately. A red-hot exhaust manifold is a serious issue that requires professional attention to prevent further damage. Ignoring it could lead to catastrophic engine failure.
