Contact Koyo for Fitment, Catalog, and Sourcing Support
Use this page when your team needs a focused answer about Cooling System Parts or Suspension & Steering Parts. Koyo can support regional parts distributors, independent repair workshops, dealer service departments, wholesale replacement-parts buyers, specialist performance garages, and OEM or OES sourcing teams. The fastest request includes vehicle context, product family, market, timing, and the reason the part is being reviewed. A cooling-system inquiry may involve radiator construction, water pump interface, thermostat operating range, or cap compatibility. A steering or suspension inquiry may involve strut selection, hub bearing references, rack-and-pinion questions, or installed environment notes.

What to include in your request
The quote form is intentionally simple, but the message should be specific. Tell Koyo whether the request concerns a radiator, water pump, thermostat, radiator cap, oil cooler, strut, hub bearing, rack-and-pinion reference, or another approved family within the two product categories. Include vehicle range, market, urgency, and whether you need catalog comparison, documentation, or sourcing direction. This helps the response avoid unnecessary follow-up and keeps technical assumptions visible.
If your team is replacing an item after a failure, include the symptom and installation context rather than only a part name. A cooling request may change when the vehicle has modified airflow, heavy-duty duty cycles, or recurring heat-soak complaints. A steering or suspension request may need notes about noise, bearing load, alignment history, or regional road conditions. These details help Koyo separate a simple catalog lookup from a request that needs application engineering review.
