Subaru engine knock after being turned off can occur due to a phenomenon known as "dieseling," where the engine continues to run briefly after the ignition is turned off. This can happen if there are hot spots in the combustion chamber that ignite residual fuel. Additionally, factors like carbon buildup or an overly rich fuel mixture can contribute to this issue. Regular maintenance and ensuring the engine is tuned properly can help mitigate this problem.

Why do fans turn on and off while 98 Subaru is off?
In a 1998 Subaru, fans may turn on and off while the vehicle is off due to the coolant temperature sensor or engine control unit (ECU) activating the cooling fans to prevent overheating. This can happen if the coolant temperature is still elevated after the engine is turned off. Additionally, a malfunctioning relay or electrical issue could cause the fans to operate unexpectedly. It's advisable to check the electrical system and cooling components if this behavior is persistent.
