14.5 In the Engine Compartment

14.5.1 Fluid Leaks

Check the engine compartment and the underbody of the vehicle

for any leaks. If you smell fuel vapor or notice any leak, have the

cause found and corrected immediately.

14.5.2 Engine Oil

Engine oil has the primary function of lubricating and cooling the

inside of the engine. It plays a major role in maintaining the engine

in proper working order. Therefore, it is essential to check the

engine oil regularly.

14.5.3 Engine Oil Consumption

It is normal for engines to consume some engine oil during

operation.

Causes of consumption in a normal engine are as follows;

• Oil is used to lubricate pistons, piston rings and cylinders. Thin

films of oil, left over when pistons move in cylinders, are sucked

into the combustion chamber due to high negative pressure

generated when the vehicle is decelerating. This oil gets burnt in

the combustion chamber

• Oil is also used to lubricate the stems of intake valves. Some of

this oil is sucked into the combustion chamber together with the

intake air and is burnt there

• Engine oil consumption depends upon the viscosity and quality of

the oil, and upon the conditions in which the vehicle is driven. Oil

consumption will be more due to high speed driving and frequent

acceleration and deceleration. A new engine may consume more

oil since its pistons, piston rings and cylinder walls are not

conditioned

14.5.4 Checking/Topping the Engine Oil

• Make sure the vehicle is on level ground

• Turn the engine OFF and wait a few minutes for the oil to settle

down into the oil sump

• Apply the parking brake

• Open the hood. Protect yourself from engine heat

• Locate and carefully remove the engine oil level dipstick
