2003 Hyundai Grandeur coolant reservoir

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.

5- 8 VEHICLE MAINTENANCE REQUIREMENTS
F060H01A-AAT
o Air Cleaner Filter A Genuine Hyundai air cleaner filter is
recommended when the filter is re- placed. F060J01A-AAT
o Spark Plugs Make sure to install new spark plugs of the correct heat range. F070C02A-AAT
o Coolant The coolant should be changed at the intervals specified in the mainte- nance schedule. F070D01A-AAT
o Manual Transaxle Oil
Inspect the manual transaxle oil ac-cording to the maintenance schedule.
NOTE: If the oil level is low, check forpossible leaks before adding oil. Do not overfill. F070E03A-AAT
o Automatic Transaxle Fluid and
Filter
The fluid level should be in the "HOT" range of the dipstick, after the engine and transaxle are at normal operatingtemperature. Check the automatic transaxle fluid level with the engine running and the transaxle in neutral,with the parking brake properly ap- plied. Use DIAMOND ATF SP-III or SK ATF SP-III when adding or chang-ing fluid. F070F01A-AAT
o Brake Hoses and Lines
Visually check for proper installation,chafing, cracks, deterioration and any leakage. Replace any deteriorated or damaged parts immediately. F070G02A-AAT
o Brake Fluid
Check brake fluid level in the brake fluid reservoir. The level should be between "MIN" and "MAX" marks on the side of the reservoir. Use onlyhydraulic brake fluid conforming to DOT 3 or DOT 4.
F070H01A-AAT
o Rear Brake Drums/Linings,
Parking Brake
Check the rear brake drums and lin-
ings for scoring, burning, leaking fluid,broken parts, and excessive wear. Inspect the parking brake system in-cluding the parking brake lever and cables. For detailed service proce- dures, refer to the Shop Manual.
F070B01A-GAT
o Cooling System Check the cooling system part, such as radiator, coolant reservoir, hosesand connections for leakage and dam- age. Replace any damaged parts.

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.

To Check the Coolant Level
The coolant level can be seen on the side of the plastic coolant reservoir. The level of the coolant should be between the "LOW" and "FULL" lineson the reservoir when the engine is cool. If the level is below the "LOW" G050C01L

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.Now fill the radiator with clean dem-ineralized or distilled water. Con- tinue to add clean demineralized or distilled water in small quantitiesuntil the fluid level stays up in the radiator neck. G050D01L

5. Start the engine, top off the radia- tor with water and then add enginecoolant to the reservoir until the level is between "LOW" and "FULL".
6. Replace the radiator and reservoir
caps and check to be sure thedrain cocks are fully closed and not leaking.
WARNING:
The cooling fan is controlled by
engine coolant temperature andmay sometimes operate even when the engine is not running. Useextreme caution when working near the blades of the cooling fan so that you are not injured by a
3. Check Section 9 for the capacity of
the cooling system in your car.Then, following the manufacturer'sdirections on the engine coolant container, add the appropriate quantity of coolant to the radiator. rotating fan blade. As the engine coolant temperature decreases, the fan will automatically shut off. Thisis a normal condition.

SPARK PLUGS
Your engine was originally equipped
with platinum-tipped spark plugs. (If installed)
Platinum-tipped spark plugs will last
longer than conventional type sparkplugs and can be identified by blue lines on the ceramic shell.Unleaded: 1.0 ~ 1.1 mm (0.039 ~ 0.043 in.) Leaded: 0.7 ~ 0.8 mm (0.028 ~ 0.032 in.)
