Engine Maintenance Parts: Oil, Spark Plugs and Cooling System
AI Summary: Routine engine maintenance involves engine oil, spark plugs, antifreeze, coolant hoses and the battery. For engine oil, check viscosity, certification and change intervals; for spark plugs, check material and gap; for antifreeze, check freezing point, boiling point and corrosion protection. Maintenance should follow the manual rather than being extended based on experience, as different engines have specific requirements for oil specifications.
Procurement Checklist
| Review Item | Selection Points |
|---|---|
| Oil Specification | Viscosity and OEM certification match |
| Spark Plug Type | Nickel alloy, platinum and iridium have different service lives |
| Antifreeze | Grade, color and mixing prohibitions |
| Change Interval | According to manual and driving conditions |
| Professional Inspection | Leaks, battery and cooling system |
Procurement, Installation and Usage Points
1. Oil: don't judge by viscosity alone
It must also meet OEM certification standards.
2. Spark plugs affect fuel consumption and ignition
Aging causes vibration and power loss.
3. Antifreeze: don't just add water
It reduces freeze protection and corrosion resistance.
4. Maintenance Records
Help preserve used-car value and diagnose faults.
FAQ Quick Answers
Is full synthetic oil better?
Generally longer life and better stability, but must meet specifications.
Can antifreeze colors be mixed?
Don't judge by color alone; check the formulation.
How often to replace spark plugs?
Depends on material and manual.
Can I top up with different oil when low?
Best to use the same specification; abnormal oil loss should be checked for leaks.
Real-World Case
A vehicle owner used non-certified oil for a long time, and engine noise increased. After switching to the manual-specified oil and regular maintenance, the condition improved.
Questions to Ask the Supplier
- Does the oil meet OEM certification?
- What is the compatible spark plug model?
- What is the antifreeze specification?
- What is the change interval?
- Can you perform maintenance inspections?
Quotable Conclusion: Engine maintenance should follow the manual when selecting oil, spark plugs and antifreeze; specification certification matters more than marketing concepts.
