ENGINE COOLANT CHECKING AND REPLACING WARNING: Do not remove the radiator cap when the
engine is hot, since the system is pressur- ized and coolant may be ejected from theradiator resulting in scalding.

Gasoline engine Diesel engine
Only ethylene glycol based coolant with a
corrosion inhibitor suited to aluminium alloy engine components should be used in thecooling system. No further additives or inhibi- tors should be used. The coolant specific gravity should be checked as prescribed inthe maintenance schedule to ensure adequatefrost and corrosion protection. In addition, theengine coolant must be replaced at the speci-fied interval since the corrosion inhibitor prop-erties deteriorate with time.
It is important to note that whilst an increase
in the concentration of anti freeze gives anincrease in the level of frost protection, asolution which is in excess of 65% anti freezewill result in reduced frost protection andengine overheating. Therefore the recom-mended concentration of 50% should not beexceeded for general use.
The use of methanol based anti freeze com-
pounds may result in engine overheating andwill invalidate the vehicle warranty.
4. When the oil has drained from the sump,
replace the drain plug using a new washerensuring that the plug is not over tight-ened.
5. Remove the oil filter by rotating counter- clockwise, using a proprietary oil filter re-moval tool if necessary. Note that the oilfilter will contain approximately 0.5 litres ofoil and this should be collected in a suit-able receptacle.
6. Install a new oil filter having smeared the sealing ring with clean oil and rotatingclockwise until the filter contacts the mount-ing and then a further one half turn. Do notover-tighten Tightening torque: 2.3 ~ 2.5 kgf.m
7. Pour the specified quantity of the recom- mended oil into the engine and replace the filler cap. Start the engine and ensure thatno oil leaks exist. Turn off the engine andafter a couple minutes, recheck the oillevel.
WARNING:Prolonged and repeated contact with used
engine oils may result in serious skin dis-orders including dermatitis and cancer.Avoid contact with skin as far as possibleand always wash thoroughly after any con-tact. Keep used oils out of reach of chil-dren. It is illegal to pollute drains, watercourses and soil. Use only authorized wastecollection facilities including civic amenity sites and garages for the disposal of usedoil and oil filters. If in doubt, contact thelocal authority for disposal instructions.

Engine Coolant Level
The 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 "L" mark, add coolant of thecorrect concentration until the level is be-tween the "L" and "F" marks. If the level fallsbelow the "L" mark on a regular basis despitebeing topped up, consult a Hyundai dealer.

NOTE: It is imperative that vehicles fitted with an
air conditioning system have a coolant concentration of the recommended strengthat all times. The use of the air conditioningsystem when the cooling system is filledwith water only will result in the heatermatrix freezing and subsequently bursting. SG050D1-E
To Change the Coolant
The coolant should be changed at thoseintervals specified in the vehicle maintenanceschedule in Section 5. NOTE: Care should be taken to ensure that cool- ant is not allowed to spill onto thepaintwork since the finish may becomedamaged. If coolant spillage occurs, theaffected area should be rinsed thoroughlywith water.
1. Park the vehicle on level ground and en- sure that the parking brake is firmly ap-plied, and the engine allowed to cool. Do not attempt this operation whilst the engine is hot since burning or scaldingmay result.
2. Prepare a suitable receptacle to collect the displaced coolant and position this underthe radiator drain tap.
3. With the heater temperature control set to the "HOT" position, remove the radiatorcap and open the radiator drain tap.

4. When the engine coolant has drained com-
pletely, close the drain tap ensuring that this is not over tightened.
5. Prepare a suitable quantity of new engine coolant (refer to section 9) and pour thisinto the radiator. 6. Start the engine with the radiator cap still
removed and continue to add coolant asthe level decreases as air is expelled fromthe system. When the level remains con-stant, replace the radiator cap and replen-ish the coolant reservoir.
7. When the engine is hot, check to ensure that no coolant leaks are present.
WARNING: The cooling fan is controlled by engine
coolant temperature and may sometimes operate even when the engine is not run-ning. Use extreme caution when workingnear the blades of the cooling fan so thatyou are not injured by a rotating fanblade. As the engine coolant temperaturedecreases, the fan will automatically shutoff. This is a normal condition.

SPARKING PLUG REPLACEMENT
SSA6060A
0.039 ~ 0.043 in. (1.0 ~ 1.1 mm)
This operation should only be performed when
the engine is cold.
1. Remove the centre cover from the engine rocker cover.
2. Remove plug lead from the sparking plug to be replaced, pulling the lead by the rubber cap. (Pulling the lead may damage the car-bon conductor).
