Questions and Answers

What is the primary function of this diesel sealing component?
It creates a robust dynamic barrier at the rear of the crankshaft to prevent pressurized engine oil from leaking into the bell housing.
Which vehicles utilize the 21443-2A200 OIL SEAL?
It is a standard fitment for 1.4L, 1.5L, 1.6L, and 1.7L CRDi U-series diesel engines found in many Hyundai and Kia passenger cars and SUVs.
What are the common symptoms of a failing rear main seal on a CRDi engine?
Look for oil seepage at the bottom of the transmission housing, a slipping clutch in manual models, or a sudden drop in engine oil levels.
Is this component a direct replacement for the original part?
Absolutely. This part is manufactured to exact OE dimensional specifications using high-temperature Viton/FKM rubber for a professional, leak-free fit.
Why should the 21443-2A200 be replaced during transmission service?
Because rear main seals are only accessible when the gearbox is removed, it is highly recommended to replace the seal during clutch or flywheel service to prevent future labor costs.
