OE 90916-03096 — Coolant Thermostat for Hyundai / Kia

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 coolant thermostat sits on the cooling 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.

Stock references leave Guangzhou within 7 working days. If 90916-03096 needs a production run, allow 25-35 days depending on quantity and surface treatment. The schedule is confirmed in writing when the order is placed.

OEM means the part was produced for the vehicle maker's assembly line; aftermarket means it is made independently to the same engineering drawing. For a coolant thermostat the practical gap is usually tooling age and packaging rather than fit, provided the tolerance class matches.

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 cooling system reference and narrow by build year. Send photos and we will cross-check the number for you.

For a short distance at reduced load, usually yes — but the risk compounds. A degraded coolant thermostat transfers stress to neighbouring components, so a small repair can grow into a full cooling system rebuild. Book the replacement once the symptom is repeatable.
