* Engine Variation: Jeep Comanches came with various engines, including 4-cylinder, 6-cylinder, and even a V8. Each engine has a different combustion process, leading to varying exhaust temperatures.
* Driving Conditions: Factors like engine load, RPM, and ambient temperature heavily influence exhaust manifold temperature. A heavily loaded engine running at high RPM in hot weather will have a significantly hotter manifold than a lightly loaded engine idling in cold weather.
* Exhaust System Condition: The age and condition of the exhaust system (manifold, pipes, muffler) can affect heat retention. A well-maintained system will dissipate heat better than one with corrosion or leaks.
However, I can provide some general information:
* Extremely Hot: Exhaust manifolds can reach very high temperatures, typically well over 1000 degrees Fahrenheit (538 degrees Celsius). This is why they are often made of heat-resistant materials like cast iron or stainless steel.
* Touch Danger: It is extremely dangerous to touch an exhaust manifold while the engine is running or shortly after it has been shut off. Severe burns are a serious risk.
If you need to work on the exhaust manifold, it's crucial to:
1. Allow the engine to cool completely. This could take several hours depending on the engine size and ambient temperature.
2. Use appropriate safety gear: Wear heat-resistant gloves and protective clothing to avoid burns.
