3- 4 WHAT TO DO IN AN EMERGENCY
check for coolant leaking from the radiator, hoses or under the car. (If the air conditioning had been in use,it is normal for cold water to be draining from it when you stop).
WARNING:
While the engine is running, keep hair, hands, and clothing away frommoving parts such as the fan and drive belts to prevent injury.
5. If the water pump drive belt is bro- ken or engine coolant is leaking out, stop the engine immediately and call the nearest Hyundai dealer for assistance.
WARNING:
Do not remove the radiator cap whenthe engine is hot. This can allowcoolant to be blown out of the open- ing and cause serious burns.
D030A01A-AAT IF THE ENGINE OVERHEATS If your temperature gauge indicates overheating, you experience a loss ofpower, or hear loud pinging or knock- ing, the engine is probably too hot. If this happens to you, you should:
1. Pull off the road and stop as soon as
it is safe to do so.
2. Place the gear selector lever in "P" (automatic), or neutral (manual transaxle) and set the parking brake.If the air conditioning is on, turn it off.
3. If engine coolant is running out un-
der the car or steam is coming outfrom the hood, stop the engine. Do not open the hood until the enginecoolant has stopped running or the steaming has stopped. If there is no visible loss of coolant and no steam,leave the engine running and check to be sure the engine cooling fan is operating. If the fan is not running,turn the engine off.
4. Check to see if the water pump drive
belt is missing. If it is not missing,check to see that it is tight. If the drive belt seems to be satisfactory, 6. If you cannot find the cause of the
overheating, wait until the engine temperature has returned normal.Then, if the engine coolant has been lost, carefully add engine coolant to the reservoir (page 6-9) to bring thefluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. Ifoverheating happens again, call a Hyundai dealer for assistance.
CAUTION:
Serious loss of engine coolant indi-cates there is a leak in the cooling system and this should be checked as soon as possible by a Hyundaidealer.

replace the drain plug using a new washer and retighten by turning itclockwise. Oil pan drain plug tightening torque : 3.5 ~4.0 kgf.m
5. Remove the oil filter by turning it counterclockwise with a oil filter wrench of the proper size. A cer- tain amount of oil will come out when you remove the filter. So besure to have your drain pan in place underneath it.
6. Install a new oil filter in accordance with the instructions on the carton or on the filter itself. Do not over-tighten. Oil filter tightening torque : 1.2 ~ 1.6 kgf.m Be sure that the mounting surface on the engine is clean and that theold gasket is removed completely. Lubricate the new gasket on the filter with clean engine oil beforeinstallation. 7. Refill the crankcase with the rec-
ommended engine oil. Refer to thespecification in chapter 9 for en-gine oil capacity.
8. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
NOTE: Always dispose of used engine oil
in an environmentally acceptable manner. It is suggested that it beplaced in a sealed container and taken to a service station for recla- mation. Do not pour the oil on theground or put it in with the house- hold trash.

G050D02A-AAT To Change the Engine Coolant The engine coolant should be changed at those intervals specified in the ve- hicle maintenance schedule in Sec-tion 5.
CAUTION:
Engine coolant can damage thefinish 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 radiator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on theradiator. Allow all the engine coolant to drain from the cooling system,then securely close the drain cock.
Use a high quality ethylene-glycol
coolant in a 50/50 mix with water. The engine coolant should be compatible with aluminum engine parts. Addi-tional corrosion inhibitors or additives should not be used. The cooling sys- tem must be maintained with the cor-rect concentration and type of engine coolant to prevent freezing and corro- sion.
Never allow the concentration of an-
tifreeze to exceed the 60% level or gobelow the 35% level or damage to thecoolant system may result. For proper concentration when adding or replac- ing the engine coolant, refer to thefollowing table.
