Frequently Asked Questions6+
How do I confirm the correct oil cooler, oil filter housing assembly, or heater control valve?+

Please send the OEM number, vehicle application, engine code, dimensions, photos, or drawing when available. For complex assemblies, OEM references and structure details are the fastest way to reduce mismatch risk before ordering.

What is included in your oil cooler assembly?+

Assembly content depends on the OE design. Some oil cooler assemblies may include the cooler body, housing-related structure, sealing components, or connection points, while others are supplied as a more complete integrated unit. We confirm the exact scope before production.

What materials and manufacturing options do you support?+

Depending on the part and OE requirement, we can review aluminum, mixed-material, or application-specific structures for oil coolers and housing assemblies, as well as valve body and sealing related requirements for heater control valves.

Do you support OEM number and cross reference supply?+

Yes. We regularly work with OEM number based inquiries and cross reference confirmation for aftermarket replacement programs. Clear OEM data helps us recommend the right configuration and quotation more efficiently.

Can I request samples or pilot quantity before a bulk order?+

Yes. For suitable items, we can discuss sample supply or pilot quantities before mass production. This helps buyers verify quality, packaging, and market acceptance with lower purchasing risk.

Can you customize packaging, barcode, or marking?+

Yes. We can support neutral packaging, custom boxes, barcode labels, and selected marking requirements according to your B2B program. Please share your packaging file or label standard together with the inquiry.
