The 23111-2G200 G4KC Crankshaft is a replacement crankshaft made for Hyundai Sonata engines that use the G4KC engine family. It is designed to restore smooth engine operation during rebuilds or repairs.
This crankshaft is intended for Hyundai Sonata vehicles equipped with the G4KC engine. Verify compatibility for your specific model year and VIN with the seller or parts catalog before purchasing.
The listing provides the part number 23111-2G200, but does not explicitly state OEM vs aftermarket. Check the vendor listing or contact the supplier to confirm whether it is genuine OEM or an OE-quality aftermarket unit.
The product description states it is made from durable materials suitable for long-lasting performance. For exact material composition (forged steel, cast steel, etc.), request technical details from the seller.
The listing does not specify. Some replacement crankshafts are factory balanced while others may require final balancing and machining. Confirm with the supplier and follow your engine builder's recommendations.
Most crankshafts are sold as the shaft only and do not include bearings, seals, or bolts. Check the product listing to see what is included or plan to purchase necessary bearings and seals separately.
Yes. This crankshaft is suitable for engine rebuilds on Hyundai Sonata engines that accept the 23111-2G200 G4KC part, provided it meets clearance and machining requirements.
It's recommended to replace main and rod bearings, crank seals, thrust washers, and any worn fasteners. Inspect rods, journals, and other rotating assembly components and perform any necessary machining.
Installation typically requires engine assembly tools such as a torque wrench, micrometers/plastigauge for bearing clearance checks, a press for fitment, and adherence to factory torque and endplay specifications. Have a qualified mechanic or machine shop perform critical measurements.
Provide your VIN and engine code (look for G4KC) to the seller or parts supplier. They can confirm fitment by cross-referencing the part number and vehicle build data.
A properly matched and installed crankshaft restores original engine smoothness and efficiency. It is a replacement component rather than a performance upgrade, unless used in conjunction with performance machining and balancing.
Follow the engine manufacturer's service manual for initial start-up, break-in procedures, and oil change intervals. Typically you should monitor oil pressure, perform an early oil and filter change, and re-check torque and clearances after initial run-in.
Warranty and return policies vary by seller. Check the specific product page or contact the vendor for details on warranty length, coverage, and return procedures before purchasing.
Inspect journals for scoring or cracks, verify straightness and journal dimensions, check oil passages for blockage, and obtain a machine shop inspection if unsure. New parts should be free of defects; used units should be professionally evaluated.
Installing a crankshaft is a precision task that requires experience measuring clearances and following torque specifications. It is recommended that a qualified mechanic or engine rebuilder perform the installation unless you have appropriate skills and tools.
