FAQ
Q: What does a cylinder liner do?
A: It provides a replaceable, wear-resistant cylindrical bore inside the engine block for the piston to move in. It maintains compression, supports the piston ring seal, and transfers heat from the combustion process to the engine cooling system.
Q: When should I replace the cylinder liner?
A: Replace when the liner bore is scored, cracked, or excessively worn beyond service limits. Common signs include low compression, oil consumption, coolant entering the combustion chamber, and loss of engine power.
Q: OEM or aftermarket?
A: High-quality aftermarket at OEM Equivalent Specifications.
Q: What is the lead time?
A: 3-5 working days for in-stock orders; 7-15 working days for bulk orders.
Q: What payment methods do you accept?
A: We accept T/T (Telegraphic Transfer). Other payment methods may be available upon request for qualified buyers.
Q: Packaging options?
A: OEM, neutral, or custom packaging available.
