OE 21310-21030 — Case ASSY FR for Hyundai / Kia

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest engine & fuel system reference and narrow by build year. Send photos and we will cross-check the number for you.

Report it with the order number and packing-list line plus photographs. Because every carton is photographed before loading, we can trace the batch immediately and settle the claim against the inspection record instead of arguing from memory.

Four variables explain most of the spread: material grade, whether the goods are new production or clearance stock, packing format, and whether the quote is ex-works or landed. Ask for the material certificate alongside the price — that is what makes a comparison like-for-like.

Position depends on the platform. On most Hyundai / Kia applications the case assy fr sits on the engine & fuel system assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

Three checks: the code printed on your old part must read 21310-21030; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

Watch for noise on cold start, vibration under load, warning lights, fluid seepage or uneven operation. Once any of those appears the case assy fr should be inspected, and reference 21310-21030 replaced if it measures outside specification.
