4. Replacement of Engine Oil
In normal case replace the engine oil per 5,000km of driving (or 3 months), and replace it per 2,500km of driving in
adverse conditions.
5. Replacement of Oil Filter
Remove the oil filter with the specialized servicing tools, and replace it per 10,000km of driving (or 6 months) in normal
case, and per 5,000km of driving (or 3 months) in adverse condition. Pay attention to the follows during the course of
replacement:
1. Check and clean the installation surface of oil filter.
(1) Check whether the component number of new oil filter is the same as that of the original one.
(2) Paste the clean engine oil upon the gasket of new oil filter.
(3) Screw in the oil filter gently, and screw it down when the gasket touches the base.
(4) Screw 3/4 rounds more with specialized servicing tools.
6. Check and replacement of spark plug
Check it per 10,000km of driving (or 6 months) in normal case, and replace it per 20,000km of driving (or 12 months).
(1) Check visually whether there’s electrode ablation or screw damage in the spark plug. Replace the spark plug if it’s
not in normal condition. The recommended spark plug is: MR479Q/MR479QA DENSO K16R-U, MR481QA/JL481Q
K7RF-11.
(2) Bend the outer side of electrode gently in order to obtain the necessary electrode clearance(0.8mm in normal case).
(3) Install the spark plug using a spark plug wrench with a torque of 18N.m.
7. Replacement of oil filter
Replace it per 40,000km (or 24 months) in normal case.
8. Check and replacement of compulsory ventilation valve PCV in crankshaft box
The PCV valve is installed to reduce the leakage of HC or other poisonous gases.
How to check the PCV valve:
(1) Blow air into the PCV valve from the cylinder cover side, and check whether it’s unblocked.
(2) Blow air into the PCV valve from the intake room side, and check whether it’s blocked.
If the PCV valve fails the above check, it shall be disqualified and replaced.
Note: Don’t take in air through the PCV valve because the petroleum substances inside are poisonous.
Check and replace it per 20,000km of driving (or 12 months) in normal case.
9. Check and replacement of all hoses and connections in engine
Check it per 40,000km of driving (or 24 months) in normal case, and replace it per 80,000km of driving (or 48 months).
