ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of
lubricating and cooling the inside of the engine. Engine oil consumption
It is normal that an engine should
consume some engine oil while nor- mal driving. The cause of oil con- sumption in a normal engine are asfollows;
o Engine oil is used to lubricate pis- tons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in the cylinder. High negative pressure generated dur-ing engine operation sucks some of the oil into the combustion cham- ber.This oil with some oil of the cylin-der wall is burned by the high tem-perature combustion gases during the combustion process.
1. Remove the oil filler cap by turning
it counter-clockwise.
2. Add oil, then check the level again. Do not overfill.
3. Replace the cap by turning it clock- wise.
The distance between the "F" and "L" marks is equal to about 1 liter(GasolineEngine)/1.2 liter(Diesel Engine) of oil.
!
! CAUTION:
Slowly pour the recommended oil using by a funnel. Do not overfill not to damage engine.
WARNING:
Be very careful not to touch the radiator hose when adding the en- gine oil as it may be hot enough to burn you.

o The engine oil consumption is strongly effected by the viscosity and quality of oil, engine rpm and driving condition etc. The engine oil is more consumed under severedriving conditions such as high speeds and frequent acceleration and deceleration than normal driv-ing condition.CHANGING THE OIL AND FILTER
!
G040A04FC-GAT
Gasoline engine
The engine oil and filter should be
changed at those intervals specified in the maintenance schedule in Sec-tion 5. If the vehicle is being driven in severe conditions, more frequent oil and filter changes are required. G040A03EThe procedure for changing the oil andfilter is as follows:
1. Park the vehicle on level ground and set the parking brake. Start the engine and let it warm up until the needle on the coolant temperaturegauge moves above the lowest mark. Turn the engine off and place the gear selector lever in "P" (auto-matic) or reverse gear (manual transaxle).
2. Open the hood and remove the engine oil filler cap.
3. Slide underneath the car and loosen the oil pan drain plug by turning itcounterclockwise with a wrench of the proper size. Be sure that adrain pan is in position to catch the oil as it drains out, then remove the drain plug.

To Change the Coolant
The coolant should be changed at those intervals specified in the ve- hicle maintenance schedule in Sec- tion 5.
! CAUTION:
Engine coolant can damage the finish of your car. If you spill en-gine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the parking brake and remove the radia- tor cap when cool.
2. Be sure your drain receptacle is in
place. Open the drain cock on theradiator. Allow all the engine cool- ant to drain from the cooling sys- tem, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car.Then, following the manufacturer's directions on the engine coolant container, add the appropriatequantity of coolant to the radiator.
!
4. Turn the radiator cap counterclock-wise without pressing down on it, until it stops. This relieves any pres- sure remaining in the cooling sys-tem. And remove the radiator cap by pushing down and turning coun- terclockwise.Fill the radiator with clean deminer-alized or distilled water. Continueto add clean demineralized or dis- tilled water in small quantities until the fluid level stays up in the radia-tor neck.
WARNING:
Remove the radiator cap when theradiator is cool.
The level of the coolant should bebetween the "L" and "F" lines on thereservoir when the engine is cold. If the level is below the "L" mark, add engine coolant to bring it up between"L" and "F". If the level is low, inspect for coolant leaks and recheck the fluid level frequently. If the level dropsagain, visit your Hyundai dealer for an inspection and diagnosis of the rea- son.
