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.

WARNING: Brake fluid is hygroscopic and should neverbe stored in an unsealed container. The pres-ence of water in the braking system will causevapour locks and increase the possibility ofbrake fade along with promoting corrosionwithin the braking system. The brake fluidmust be changed at the specified time ormileage interval to ensure continued safeoperation of the system. Brake fluid will causerapid and serious damage to paintwork. Ifaccidental spillage occurs, the affected areamust be rinsed with water immediately. Donot allow brake fluid to come into contactwith the eyes or to be ingested and ensurethat fluid is safely stored away form the reachof children. SG130A1-C CHECKING THE CLUTCH FLUID (Not all models)To Check the Clutch Fluid The clutch fluid level in the master cylinder should be checked when performing other under bonnetchecks. The system should be checked for leak-age at the same time.Ensure that the clutch fluid level is always be-tween the "MAX" and "MIN" level markings onthe fluid reservoir. Fill as required. Fluid lossindicates a leak in the clutch system whichshould be inspected and repaired immediately.
SG130B2-E Adding FluidRecommended brake fluid conforming to DOT 3 or DOT 4 should be used. The reservoir cap mustbe fully tightened to avoid contamination fromforeign matter or moisture. CAUTION: Brake fluid is hygroscopic and should neverbe stored in an unsealed container. Do notallow petroleum base fluid to contaminatethe brake fluid since damage to the rubberseals of the system may result. WARNING: Brake fluid will cause rapid and serious dam-age to paintwork. If accidental spillage oc-curs, the affected area must be rinsed withwater immediately. Do not allow brake fluidto come into contact with the eyes or to beingested and ensure that fluid is safely storedaway form the reach of children. SG140A1-E AIR CONDITIONING SYSTEMMAINTENANCE Condenser Ensure that the condenser is periodically in- spected and that accumulations of dirt, deadinsects and leaves etc, are removed to ensurethat the efficiency of the system is not impaired.Care must be exercised to ensure that the con-denser fins are not damaged during cleaning.

EMISSION CONTROL SYSTEM 7-1
SH010A1-E EMISSION CONTROL SYSTEMS (Not all models) Depending upon the market for which the vehicleis destined, the emission control system willcomprise one or more of the following emissioncontrol devices. (1) Crankcase emission control system (2) Evaporative emission control system(3) Exhaust emission control system In order that the proper functioning of the emis- sion control systems may be ensured, it isrecommended that the vehicle is inspected andmaintained by an authorized Hyundai dealer inaccordance with the maintenance schedule inthis manual.

CONTROL SYSTEM
SH010B1-E
1. CRANKCASE EMISSION CONTROL SYSTEM
The positive crankcase ventilation system is employed to prevent air pollution caused byblow-by gases being emitted from the crankcase by introducing fresh air to the crankcase throughthe air cleaner where this mixes with blow-bygases and then passes through the PCV valveinto the intake manifold from where it subse-quently enters the combustion chamber and isburned.
SH010D1-E
3. EXHAUST EMISSION CONTROL SYSTEM The exhaust emission control system is a highlyeffective system which controls exhaust emis-sion while maintaining good vehicle performance.
SH010C1-E
2. EVAPORATIVE EMISSION CONTROL SYSTEM
The Evaporative Emission Control System is designed to prevent fuel vapours from escapinginto the atmosphere through the fuel tank venti-lation system.Whilst the engine is not running, fuel vapours generated inside the fuel tank are absorbed and stored in a charcoal canister. When the engine isstarted, the vapours stored in the canister aredrawn into the induction system through thepurge control solenoid valve and are subse-quently burned.The purge control solenoid valve is controlled bythe ECU; when the engine coolant temperatureis low or the engine is idling, the purge controlvalve is closed and fuel vapours remain stored inthe canister. Under normal running conditionswhen the engine is warm, the valve opens andthe vapours are drawn into the inlet tract andsubsequently burned in the combustion cham-ber. SH020A1-E CATALYTIC CONVERTOR OPERATING PRECAUTIONS Hyundai Coupe models are fitted with catalytic convertors which require special operating con-siderations. The catalytic convertor serves tooxidize certain noxious elements of the exhaustgases leaving the engine to reduce the level ofpollutants emitted from the vehicle and, providedthat care is exercised to prevent damage, thecatalyst will operate efficiently for the life of thevehicle.It is of the utmost importance that the followinginformation is read and understood by the ve-
