G040A02GK-EAT ENGINE OIL AND FILTER REPLACEMENT The engine oil and filter must be changed at the time or mileage interval specified in the mainte-nance schedule. If the vehicle is operated undersevere or adverse conditions, the oil and filtermust be replaced more frequently.To replace the oil and filter, proceed as follows:
1. Ensure that the engine is at normal operating
temperature and park the vehicle on level ground with the parking brake securely ap-plied and the engine turned off.
2. Open the bonnet and remove the oil filler cap.
3. Prepare a suitable receptacle to collect the displaced oil and remove the drain plug fromthe sump.
G350A01A-GAT 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 normal driving. The cause of oilconsumption in a normal engine are as follows;
o Engine oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil is left on the cylinder wall whena piston moves downwards in the cylinder.High negative pressure generated during en-gine operation sucks some of the oil into thecombustion chamber.This oil with some oil of the cylinder wall isburned by the high temperature combustiongases during the combustion process.
o The engine oil consumption is strongly ef- fected by the viscosity and quality of oil,engine rpm and driving condition etc.More engine oil may be consumed undersevere driving conditions such as high speeds,frequent acceleration and deceleration, com-pared to normal driving.

ways wash thoroughly after any contact. Keep used oils out of reach of children. It is illegalto pollute drains, water courses and soil. Useonly authorized waste collection facilitiesincluding civic amenity sites and garages forthe disposal of used oil and oil filters. If indoubt, contact the local authority for dis-posal instructions. SG050A1-E ENGINE COOLANT CHECKING AND REPLACING WARNING: Do not remove the radiator cap when the engine is hot, since the system is pressurizedand coolant may be ejected from the radiatorresulting in scalding. SG050B1-E Coolant recommendations
Only ethylene glycol based coolant with a corro- sion inhibitor suited to aluminium alloy enginecomponents should be used in the cooling sys-tem. No further additives or inhibitors should beused. The coolant specific gravity should bechecked as prescribed in the maintenance sched-ule to ensure adequate frost and corrosion pro-tection. In addition, the engine coolant must bereplaced at the specified interval since the corro-sion inhibitor properties deteriorate with time.It is important to note that whilst an increase in theconcentration of anti freeze gives an increase inthe level of frost protection, a solution which is inexcess of 65% anti freeze will result in reducedfrost protection and engine overheating. There-fore the recommended concentration of 50%should not be exceeded for general use.The use of methanol based anti freeze com-pounds may result in engine overheating and willinvalidate the vehicle warranty. NOTE: It is imperative that vehicles fitted with an airconditioning system have a coolant concen-tration of the recommended strength at alltimes. The use of the air conditioning systemwhen the cooling system is filled with wateronly will result in the heater matrix freezingand subsequently bursting.SG050C1-E Engine Coolant LevelThe engine coolant level may be observed through the side of the plastic coolant reservoir(expansion tank) when the engine is cold. If thelevel is below the "LOW" mark, add coolant of thecorrect concentration until the level is betweenthe "LOW" and "Full" marks. If the level fallsbelow the "LOW" mark on a regular basis despitebeing topped up, consult a Hyundai dealer. SG050D1-E To Change the Engine CoolantThe engine coolant should be changed at those intervals specified in the vehicle maintenanceschedule in Section 5. NOTE: Care should be taken to ensure that coolantis not allowed to spill onto the paintworksince the finish may become damaged. Ifcoolant spillage occurs, the affected areashould be rinsed thoroughly with water.
1. Park the vehicle on level ground and ensure
that the parking brake is firmly applied, and the engine allowed to cool.DO NOT ATTEMPT THIS OPERATIONWHILST THE ENGINE IS HOT SINCEBURN-ING OR SCALDING MAY RESULT.
2. Prepare a suitable receptacle to collect the displaced coolant and position this under theradiator drain tap.

6-8 CAUTION: Sparking plugs must only be cleaned usingpurpose designed equipment. Wire brushingmay damage the centre electrode insulatorcausing mis-firing to occur. Only the correctgrade of sparking plug should be used. Useof an incorrect grade may result in seriousengine damage.
3. With the heater temperature control set to the
"HOT" position, remove the radiator cap andopen the radiator drain tap.
4. When the engine coolant has drained com- pletely, close the drain tap ensuring that thisis not over tightened.
5. Prepare a suitable quantity of new engine coolant (refer to section 9) and pour this intothe radiator.
6. Start the engine with the radiator cap still removed and continue to add coolant as thelevel decreases as air is expelled from thesystem. When the level remains constant,replace the radiator cap and replenish thecoolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks are present.
WARNING:The cooling fan is controlled by engine cool-ant temperature and may sometimes operateeven when the engine is not running. Useextreme caution when working near the bladesof the cooling fan so that you are not injuredby a rotating fan blade. As the engine coolanttemperature decreases, the fan will automati-cally shut off. This is a normal condition. G060B02GK-EAT SPARKING PLUG REPLACEMENT This operation should only be performed when the engine is cold.
1. Remove the engine rocker cover.NOTE: It is recommended that the spark plug forEngine 2.7L should be changed by an autho-rized Hyundai dealer.
2. Remove plug lead from the sparking plug to
be replaced, pulling the lead by the rubber cap. (Pulling the lead may damage the carbonconductor).
3. Clean around the base of the plug to be removed, and install the plug socket ensuringthat the ceramic insulator does not becomedamaged. Turn the socket counterclockwiseto remove the plug.
