2004 Hyundai Matrix cooling

WHAT TO DO IN AN EMERGENCY 3-3
WARNING: While the engine is running, keep hair, hands, and clothing away from moving parts such as the fan and drive belts to prevent injury. WARNING (Diesel only): Never work on injection system with engine running or within 30 seconds after shutting off engine. High pressure pump, rail, injec- tors and high pressure pipes are subject to high pressure even after the engine stopped. The fuel jet produced by fuel leaks may cause serious injury, if it touch the body. People using pacemakers should not move than 30cm closer to the ECU or wiring harness within the engine room while engine is running, since the high currents in the Common Rail system produce considerable magnetic fields.
5. If the water pump drive belt is broken or
coolant is leaking out, stop the engine im- mediately and call the nearest Hyundai deal- er for assistance.
WARNING: Do not remove the radiator cap when the engine is hot. This can allow coolant to be blown out of the opening and cause serious burns. 2. The spare tire should only be used temporari-
ly and should be returned to the luggage compartment as soon as the original tire can be repaired or replaced.
3. Continuous use at speeds of over 80 km/h (50 mph) is not recommended.
4. As the temporary spare tire is specifically designed for your car, it should not be used on any other vehicle.
5. The temporary spare tire should not be used
on any other wheels, nor should standard tires, snow tires, wheel covers or trim rings be used with the temporary spare wheel. If such use is attempted, damage to these items or other car components may occur.
6. The temporary spare tire pressure should be
checked once a month while the tire is stored.
CAUTION:
o Do not use snow chains with your tempo- rary spare tire.
o Do not use more than one temporary spare tire at a time.
D040A01FC-GAT TEMPORARY SPARE TIRE The following instructions for the temporary spare tire should be observed:
1. Check inflation pressure as soon as possible
after installing the spare tire, and adjust to the specified pressure. The tire pressure should be periodically checked and maintained at the specified pressure while the tire is stored.
Inflation Pressure
Tire Size
T115/70R(D)15 420 kPa (60 psi)
Spare Tire Pressure
6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has returned to normal. Then, if the engine cool- ant has been lost, carefully remove the radia- tor cap and add engine coolant to bring the fluid level in the reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur- ther signs of overheating. If overheating hap- pens again, call a Hyundai dealer for assis- tance.
CAUTION: Serious loss of engine coolant indicates there is a leak in the cooling system and this should be checked as soon as possible by a Hyundai dealer.

ENGINE OIL CONSUMPTION Function of Engine Oil
Engine oil has the primary function of lubricat-
ing 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 oil consumption in a normal engine are asfollows;
o Engine oil is used to lubricate pistons, piston rings and cylinders. A thin film of oil is left on the cylinder wall when a piston moves downwards in thecylinder. High negative pressure generated
during engine operation sucks some of theoil into the combustion chamber. This oil with some oil of the cylinder wall is burned by the high temperature combustion gases 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. Theengine oil is more consumed under severedriving conditions such as high speeds and
frequent acceleration and deceleration thannormal driving condition.
G040A03FC-GAT
CHANGING THE OIL AND FILTER (GASOLINE ENGINE)
The engine oil and filter should be changed at
those intervals specified in the maintenance schedule in Section 5. If the car is being drivenin severe conditions, more frequent oil and filterchanges are required.
The procedure for changing the oil and filter is
as follows: 1. Park the car on level ground and set the
parking brake. Start the engine and let itwarm up until the needle on the coolanttemperature gauge moves above the lowestmark. Turn the engine off and place the gearselector lever in "P" (automatic) or reversegear (manual transaxle).
2. Open the hood and remove the engine oil filler cap.
3. Slide underneath the car and loosen the oil pan drain plug by turning it counterclock-wise with a wrench of the proper size. Besure that a drain pan is in position to catchthe oil as it drains out, then remove the drainplug.
WARNING:Be very careful when draining the engine oilas it may be hot enough to burn you!
4. When the oil has stopped draining, replace the drain plug using a new washer andretighten by turning it clockwise. Oil pan drain plug tightening torque: 1.6DOHC (European Community only: 4.0 ~4.5
kgf.m, Except European Comunity: 3.5 ~4.5 kgf.m) 1.8DOHC: 4.0 ~4.5 kgf.m
5. Remove the oil filter by turning it counter- clockwise with a oil filter wrench of the proper size. A certain amount of oil willcome out when you remove the filter. So besure to have your drain pan in place under-neath it.

6. Loosen the oil filter upper cap with a proper tool from the lower case until an O-ring is seen. Then, drain the oil completely.
7. Pull out the oil filter upper cap with element from the lower case. Using a clean cloth, remove any dirt or oil accumulated around the lower case.
8. Install a new copper washer of the oil filter drain plug by the side of lower case andretighten by turning it clockwise.
Tightening torque : 0.8 ~ 1.0 kgf.m
9. After mounting a new oil filter element and new O-ring to upper cap, install the upper cap to lower case and retighten by turning itclockwise. Do not over-tighten.
Tightening torque : 2.3 ~ 2.5 kgf.m
10. Refill the crankcase with the recommended engine oil. Refer to the specification in chap- ter 9 for engine oil capacity.
11. Start the engine and check to be sure no oil is leaking from the drain plug or oil filter.
12. Shut off the engine and recheck the oil level.
NOTE: It is recommended that the engine oil and
filter should be changed by an authorized Hyundai dealer. G050A01A-AAT
CHECKING AND CHANGING THE ENGINE COOLANT
WARNING: Do not remove the radiator cap when the
engine is hot. When the engine is hot, the engine coolant is under pressure and mayerupt through the opening if the cap isremoved. You could be seriously burned ifyou do not observe this precaution. Do notremove the radiator cap until the radiator iscool to the touch. NOTE: Always dispose of used engine oil in an environmentally acceptable manner. It is sug-gested that it be placed in a sealed containerand taken to a service station for maybereclaimation. Do not pour the oil on theground or put it into the household trash. WARNING: Used motor oil may cause irritation or
cancer
of the skin if left in contact with the skin for prolonged periods of time. Wash your handsthoroughly with soap and warm water assoon as possible after handling used oil.

To Check the Coolant Level
G050C01FC
The coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool- ant should be between the "LOW" and "FULL"lines on the reservoir when the engine is cold.If the level is below the "LOW" mark, addengine coolant to bring it up between "LOW"and "FULL". If the level is low, inspect for G050D02A-AAT
To Change the Coolant The coolant should be changed at those inter-
vals specified in the vehicle maintenance sched-ule in Section 5.
CAUTION: Engine coolant can damage the finish of
your car. If you spill engine coolant on the car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park- ing brake and remove the radiator cap when cool.
2. Be sure your drain receptacle is in place. Open the drain cock on the radiator. Allowall the engine coolant to drain from thecooling system, then securely close the draincock.
3. Check Section 9 for the capacity of the cooling system in your car. Then, followingthe manufacturer’s directions on the enginecoolant container, add the appropriate quan-tity of coolant to the radiator.
