Questions and Answers

What is the primary function of this sealing component?
It creates a high-pressure dynamic barrier around the rear of the crankshaft to prevent engine oil from leaking out into the transmission area.
Which vehicles utilize the 21443-02501 OIL SEAL?

It is a standard fitment for the 1.0L and 1.1L engines found in the Hyundai i10, Atos, Eon, and Kia Picanto (SA/TA models).

What are the common symptoms of a failing rear main seal?

The most common sign is oil dripping from the junction where the engine meets the transmission, often leading to a slipping clutch in manual vehicles.

Absolutely. This part is manufactured to meet exact OE specifications using heat-resistant synthetic rubber for a professional, leak-free fit.
