Wait a minute, pull the dipstick out, wipe it clean, reinsert the dipstick all the way and then pull it out. Check the oil level on the dipstick. It must be between the marks «FULL» («Full») And «LOW» («Short») on the dipstick (pic. 1.155).
Topping up engine oil
Pic. 1.156. Topping up engine oil
If the oil level is at or below the mark «L» («Short») on the dipstick, add oil to the mark «F» («Full»). To do this, unscrew the engine oil filler cap by turning it counterclockwise. Add oil and check the oil level again (pic. 1.156).
Do not add more oil than required.
Install the plug by turning it clockwise.
Distance between marks «R («Full») And «L» («Short») on the dipstick corresponds to approximately 1 l of engine oil.
Engine oil consumption
Engine oil is used to lubricate pistons, piston rings and cylinders (part of it enters the combustion chamber and burns). A thin layer of engine oil remains on the cylinder walls as the pistons move down. The vacuum generated during engine operation draws some oil into the combustion chamber. This oil, as well as oil from the cylinder walls, is burned during the combustion of the air-fuel mixture in the combustion chamber.
Oil consumption is strongly influenced by oil viscosity and quality, engine speed, driving conditions, etc. The engine consumes more oil under severe operating conditions, such as high speeds and frequent acceleration and deceleration.
Changing engine oil and oil filter (for petrol engines)
Pic. 1.157. Drain and filler oil plugs of a gasoline engine
The engine oil and oil filter must be changed at the intervals indicated on the periodic maintenance chart in the service book. The engine oil and oil filter need to be changed more frequently when the vehicle is operated under severe operating conditions.
The engine oil and oil filter must be changed in the order shown below.
1. Park your vehicle on level ground and apply the parking brake. Start the engine and let it run until the pointer of the coolant temperature gauge rises above the minimum mark on the scale. Turn off the engine and move the selector to the position «R» («Parking») (Automatic transmission) or shift lever to reverse gear position (Manual Transmission).
2. Open the hood and remove the engine oil filler cap.
3. From the bottom of the vehicle, loosen the drain plug by turning it counterclockwise with an appropriate wrench. Before completely unscrewing the drain plug, make sure that the draining oil will fall into a container specially prepared for this, unscrew the plug and drain the oil.
4. After a little drain, install the drain plug with a new sealing washer and tighten it by turning it clockwise.
Drain plug tightening torque: 35–45 Nm.
5. Remove the oil filter. Unscrew the filter by hand. Substitute a specially prepared oil drain container under the oil filter, as a small amount of oil will flow out of it after unscrewing it.
6. Install a new oil filter following the instructions on the packaging or on the filter itself. Don't overtighten it. Make sure the engine crankcase mounting surface is clean and free of old gasket residue. Lubricate the gasket of the new filter with a small amount of fresh engine oil.
7. Fill the crankcase with the recommended amount of engine oil.
8. Start the engine and check for oil leakage from the oil filter and drain plug.
9. Stop the engine and recheck the oil level.
Note. Always dispose of used engine oil properly. It is recommended to place the oil in a sealed container and take it to a service station for disposal. Do not pour used engine oil on the ground or dispose of it with household waste.
Engine coolant
Pic. 1.158. Gasoline engine coolant expansion tank
Use 50% ethylene glycol based coolant in water. The engine coolant must be compatible with aluminum parts. Additional additives and anti-corrosion additives should not be used. Coolant must be of the correct concentration and type to prevent freezing and corrosion.
Attention! Do not open the radiator cap until the engine is cold. The cooling system is pressurized and opening the plug may cause hot fluid to escape and cause severe burns. Do not open the radiator cap until you can safely touch the radiator with your hand.
The concentration of antifreeze should not be higher than 60% and lower than 35%, otherwise the cooling system may be damaged. The correct concentration of antifreeze when adding or replacing it is indicated in table 1.6.
Checking the coolant level
Pic. 1.159. Coolant level marks on expansion tank
The coolant level can be seen on the side of the plastic expansion tank. For a cold engine, the coolant level in the reservoir must be between the marks «LOW» («Short») And «FULL» («Full»). If the coolant level is below the mark «LOW», bring it up to the required level. In this case, check for leaks in the cooling system. Check the coolant level as often as possible.
Engine Coolant Replacement
1. Park the vehicle on a level surface, apply the parking brake, and when the engine is cold, remove the radiator cap.
2. Make sure the coolant drain container is in place. Open the radiator drain cock. Allow the coolant to completely drain from the cooling system, then close the cock tightly.
3. Following the coolant manufacturer's instructions, add the correct amount of coolant to the radiator. Then fill the radiator with distilled or demineralized water. Pour distilled or demineralized water in small portions until it appears in the radiator neck.
4. Start the engine, add water to the radiator, and then add coolant to the expansion tank so that its level is between the marks «LOW» And «FULL».
5. Install the radiator and expansion tank caps and make sure that the drain cocks are closed and not leaking.
Attention! The cooling system radiator fan turns on depending on the engine coolant temperature and may sometimes come on when the engine is not running. Be especially careful when working near fan blades to avoid injury from rotating blades. As the coolant temperature drops, the fan turns off automatically. This is normal.
Spark plug
Pic. 1.160. Checking the spark plug
Spark plugs should be changed in accordance with the vehicle maintenance schedule specified in the service book, or if the engine efficiency has noticeably decreased. Signs of reduced engine efficiency are: reduced power at increased load, increased fuel consumption, low acceleration, etc. When replacing spark plugs, always use spark plugs recommended by Hyundai. Use of other spark plugs may result in reduced engine efficiency, radio interference and engine damage.
Replacing spark plugs
Spark plugs are best changed when the engine is cold. Change the spark plugs one at a time. This will help to avoid incorrect connection of high voltage wires.
1. Remove the center cap which is located on the engine valve cover.
2. Use a clean cloth to remove any dirt deposits that have accumulated around the spark plug so that they cannot get into the cylinder when the spark plug is removed.
3. To remove the high voltage spark plug wire, pull on the insulated end. Pulling directly on the wire may damage the carbon conductive core.
4. When installing the spark plug wrench and unscrewing the old spark plug, do not damage its ceramic insulation.
Pic. 1.161. Removing the spark plug
5. To remove the spark plug, turn it counterclockwise (pic. 1.161).
Pic. 1.162. Installing the spark plug
6. When installing a new spark plug, be careful not to damage the ceramic insulation (pic. 1.162).
Note. All spark plugs should be tightly tightened, but overtightening a spark plug can damage the threads in the aluminum cylinder head, and overtightening it can cause the spark plug to heat up and possibly damage the engine.
7. Install the high voltage wire directly on the electrode. Make sure it is securely fixed and will not fall out.
Air filter replacement
Pic. 1.163. Air filter
To replace the air filter, unfasten the clips around the cover (pic. 1.163).
After that, lift the cover up, remove the old filter and replace it with a new one. It is recommended to use only original Hyundai spare parts.
Attention! Operating the vehicle without an appropriate air filter can result in increased engine wear.
Windshield wiper blades
Pic. 1.164. Removing the wiper blades
From time to time it is necessary to check the windshield wiper blades and clean them of accumulated dirt. To clean the wiper blades and arms, use a clean sponge or cloth dampened with a neutral detergent solution. If the wiper blades continue to leave streaks on the glass, replace them with genuine Hyundai or equivalent blades.
Attention! Do not operate wiper blades on dry glass. This can cause them to wear out quickly and scratch the glass.
Filling the washer reservoir
Pic. 1.165. washer reservoir
The windshield washer uses water from the reservoir. Fill the reservoir with good quality windshield washer fluid. If you use the washer frequently, check the fluid level in the reservoir more often.
The capacity of the windshield washer reservoir is 3 liters.
Attention! Do not overfill the washer reservoir, and do not use the washer when there is no fluid in the reservoir. This could damage the washer pump.
Checking the oil level in the gearbox (Manual Transmission)
Pic. 1.166. Drain and filler plugs for manual transmission
The oil level in the gearbox must be checked at the intervals specified in the service book.
For a manual transmission, use only Hyundai 75W/90 gear oil (according to API GL-4 classification).
The volume of oil to be filled into the manual transmission is 2.15 liters.
Attention! The oil level in the gearbox is best checked when the engine is cold. If the engine is hot, be very careful not to burn yourself on hot engine or exhaust system parts.
Checking the oil level in the gearbox housing
Pic. 1.167. Checking the oil level in the gearbox housing
Park the vehicle on level ground and turn off the engine.
1. Using an appropriate wrench, loosen the fill plug by turning it counterclockwise and turn it all the way out by hand.
2. Check the oil level in the gearbox housing with your finger or an appropriate tool. The oil level should be at the level of the lower edge of the filler plug hole. If the oil level is low, check for oil leaks before adding oil. Fill or add oil to the gearbox very carefully. Do not add too much oil.
3. Install the plug, screw it in by hand, and then tighten it firmly with a wrench.
Checking the oil level in the gearbox (Automatic transmission)
The oil level in the automatic transmission must be checked at the intervals specified in the service book.
The vehicle's automatic transmission is designed to use DIAMOND ATF SP-III or SK ATF SP-III oil.
The volume of oil poured into the automatic transmission is 6.1 liters (for car with 1.6L DOHC engine) and 6.7 l (for car with 1.8L DOHC engine).
Attention! The oil level in an automatic transmission should be checked at normal engine coolant operating temperature. This means that the engine, radiator, exhaust system, etc. will be very hot. Be especially careful when performing this operation.
Pic. 1.168. Location of the automatic transmission dipstick
Park the vehicle on level ground and apply the parking brake. When checking the oil level in an automatic transmission, the oil should be at normal operating temperature and the engine should be running at idle speed.
With the engine running at idle speed, press the brake pedal and move the automatic transmission selector lever from the position «R» sequentially into positions «FT, «N» And «D». Then put it back in position «N». After that, without turning off the engine:
1. Carefully open the hood so that hands, long hair or clothing do not get caught in the rotating parts.
2. Remove the automatic transmission dipstick, wipe it dry, insert as far as it will go and remove it again. Check the oil level on the dipstick. It should be between the two marks on the dipstick «NOT («Hot»).ATF level must be in the range «NOT» (pic. 1.169).
Pic. 1.169. Measuring probe
3. If the oil level is low, use a funnel to add oil through the dipstick hole until the level is between the marks on the dipstick «NOT». Do not add too much oil.
Checking the brake fluid level
It is necessary to periodically check the level of brake fluid in the reservoir.
Attention! Use only DOT 3 or DOT 4 approved brake fluid in your vehicle's brake system. Follow the instructions on the brake fluid packaging.
Pic. 1.170. Brake fluid reservoir
The brake fluid level must be between the marks on the reservoir «MAX» («Maximum») And «MIN» («Minimum»). If the brake fluid level is at or below the «MIN», carefully add fluid up to the mark «MAX». Do not add too much brake fluid.
Adding brake fluid
When adding brake fluid, first remove the dirt and remove the brake fluid reservoir cap. Slowly add the required amount of brake fluid. Do not add too much brake fluid. Carefully install the cap on the tank and tighten it.
Checking the fluid level in the clutch fluid reservoir
When carrying out car maintenance operations under the hood, it is necessary to check the fluid level in the reservoir of the clutch master cylinder. At the same time, it is necessary to check for leaks in the clutch hydraulic system. The brake fluid level must be between the marks on the clutch master cylinder reservoir «MAX» («Maximum») And «MIN» («Minimum»).
Pic. 1.171. Clutch reservoir
Add fluid if necessary. Fluid leakage indicates a leak in the clutch hydraulic system, which must be repaired immediately.
Clutch Fluid Replacement
Replace only with DOT 3 or DOT 4 approved brake fluid. Tighten the reservoir cap securely to prevent contamination of the clutch hydraulic system.
