Procurement, Installation and Usage Points
1. Replace the three filters on schedule
Oil filters are replaced with the oil; air filters and cabin filters are adjusted according to the environment.
2. The timing system cannot be delayed
A break can cause severe engine damage.
3. Check seal material
Insufficient oil and temperature resistance will cause leaks.
4. Re-inspect after repair
After startup, check for oil leaks, abnormal noise and warning lights.
FAQ Quick Answers
Can I change only the oil without changing the oil filter?
Not recommended; the old oil filter contains contaminants.
How often should the timing belt be replaced?
Follow the manufacturer's maintenance manual.
Are parts interchangeable?
Most require matching by vehicle model and part number.
Are aftermarket parts necessarily inferior?
Quality varies greatly; choose reliable brands.
Practical Case
A vehicle owner delayed replacing the timing kit, and the belt eventually broke, causing a major overhaul. After replacing the complete set according to the manual, the risk was avoided.
Questions to Ask the Supplier
