▷ Temporarily, the engine may run less
smoothly.
▷ A somewhat higher engine speed is neces‐
sary to reach usual performance.
▷ A slight amount of smoke coming from the
exhaust system, even after the engine is
switched off.
▷ Noises, such as those caused by the radiator
fan running, even some minutes after the en‐
gine is switched off.
