The engine is lubricated when the oil is hot and circulates at a certain pressure. How will we know that this lubrication is correct?
A)Because the pressure indicator will be off.Correct
B)Because the pressure indicator will be on.
C)Because when the cylinder head cap is removed with the engine stopped, smoke comes out.
The oil pressure indicator will light up on the vehicle's dashboard when the pressure is insufficient and therefore the lubrication is not correct. As long as there is no lubrication problem, the indicator will remain off.
