Engine Lubrication: Service and Repair

CHANGING ENGINE OIL





1. Run the engine until it reaches normal operating temperature.
2. Stop the engine.
3. Remove the oil filler cap (on rocker cover) and the drain plug (on the oil pan). Drain the engine oil.
4. Re-install and tighten the drain plug to the specified torque.

Tightening torque:
Drain plug: 35 - 45 Nm (350 - 450 kgs.cm, 25 - 33 ft. lbs.)

5. Fill the crankcase with fresh engine oil through the oil filler cap opening.

Capacity:
Dry fill: 4.3 liters (4.5 U.S.Qts., 3.8 Imp.Qts.)
Drain and refill:
Without oil filter: 3.7 liters (3.91 U.S.Qts., 3.25 Imp.Qts.)
With oil filter: 4.0 liters (4.23 U.S.Qts., 3.51 Imp.Qts.)

CAUTION: Do not overfill the crankcase. This will cause oil aeration and loss of oil pressure.

6. Install the oil filler cap.
7. Start and run the engine.
8. Stop the engine and then check the oil level. Add oil if necessary.

REPLACEMENT-OIL FILTER
All Hyundai Motor Company engines are equipped with a high quality, throw-away oil filter. This filter is recommended as a replacement filter on all vehicles. The quality of replacement filters varies considerably.

Only high quality of replacement filters should be used to assure the most efficient service. Make sure that the rubber gasket from the old oil filter is completely removed from the mating surface on the engine block, before installing the new filter.

REPLACING OIL FILTER





1. Use a filter wrench to remove the oil filter
2. Before installing the new oil filter on the engine, apply clean engine oil of the surface of the rubber gasket.
3. Tighten the oil filter of the specified torque.

Oil filter: 17 - 25 Nm (170 - 250 kgs.cm, 12 - 18 ft. lbs.)





4. Start and run the engine and check for engine oil leaks.
5. After stopping the engine, check the oil level and add oil as necessary.


OIL PRESSURE SWITCH





1. If "OIL PRESSURE" indicating lamp lightens when ignition switch is set to "ON" and goes out when engine is started and runs at idle, then everything is in order. If "OIL PRESSURE" lamp does not lighten when ignition switch is set to "ON," check switch, lamp and wiring.





2. If there is current flow when ignition switch is set to "ON" and if there is no current flow when engine is running at idle, switch is good.

If switch is good, check lamp and wiring.

Pressure of oil switch operation: 14.71 - 29.42 kPa (0.15 - 0.3 kg/cm2,2.1 - 4.3 psi)

3. Using the special tool (09260-32000), tighten the switch to the specified torque.

NOTE: Do not overtorque the oil pressure switch

Oil pressure switch and sender assembly: 8 - 12 Nm (80 - 120 kgs.cm, 5.8 - 8.7 ft. lbs.)

INSPECTION
Oil Pressure Switch





1. Use an ohmmeter to check the continuity between the terminal and the body. If there is no continuity, replace the oil pressure switch.





2. Check the continuity between the terminal and the body when the fine wire is pushed. If there is continuity even when the fine wire is pushed, replace it.
3. If there is no continuity when a 50 kPa (7 psi) vacuum is applied through the oil hole, the switch is operating properly. Check to see that air doesn't leak. If air leaks, the diaphragm is broken. Replace the switch.

INSTALLATION
1. Apply sealant to threaded portion.
2. Using special tool (09260-32000), tighten switch to specified torque.

Tightening torque:
Oil pressure switch: 8 - 12 Nm (80 - 120 kgs.cm, 5.8 - 8.7 ft. lbs.)
