|
Problem | Possible cause | Action | |
1. Temporary noise when starting a cold engine | Normal | This noise will disappear after the oil in the engine reaches the normal pressure. | |
2. Continuous noise when the engine is started after parking more than 48 hours | Oil leakage of the high pressure chamber on the HLA, allowing air to get in | Noise will disappear within 15 minutes when engine runs at 2000-3000 rpm. If it doesn’t disappear, refer to step 7 below. | |
3. Continuous noise when the engine is first started after rebuilding cylinder head | Insufficient oil in cylinder head oil gallery | ||
4. Continuous noise when the engine is started after excessively cranking the engine by the starter motor or band |
| ||
5. Continuous noise when the engine is running after changing the HLA |
| ||
6. Continuous noise during idle after high engine speed | Engine oil level too high or too low |
| |
Excessive amount of air in the oil at high engine speed | Check oil supply system. | ||
Deteriorated oil | Check oil quality. If deteriorated, replace with specified type. | ||
7. Noise continues for more than 15 minutes | Low oil pressure | Check oil pressure and oil supply system of each part of engine. | |
Faulty HLA | Remove the cylinder head cover and press HLA down by hand. If it moves, replace the HLA. |

Hyundai Tucson (LM) 2010-2015 Owners Manual: Check tire inflation pressure
Check your tires, including the spare tire, once a month or more.
How to check
Use a good quality tire pressure gauge to check tire pressure. You can not tell
if your tires are properly inflated simply by looking at them. Radial tires may
look properly inflated when they are under-inflated.
