Does the Engine Running Rich Cause a Car to Overheat?
An engine running rich occurs when the air-fuel mixture contains more fuel than the stoichiometric ratio. This can lead to a variety of problems, including decreased fuel economy, increased emissions, and, potentially, overheating.
When an engine runs rich, the excess fuel is burned in the exhaust manifold, which can raise the temperature of the exhaust system and the engine itself. This can, in turn, lead to overheating if the engine is not properly cooled.
However, it's important to note that running rich is not the only cause of overheating. Other potential causes include a faulty cooling system, a clogged radiator, or a leaking head gasket. If you're experiencing overheating, it's important to have your car inspected by a qualified mechanic to determine the underlying cause.
