Seal the left-side joint between the cylinder head and the engine block with the APEX Automobile Parts Inc Cylinder Head Gasket, part number AHG242L, which is designed to hold combustion pressure in the cylinders and keep the oil and coolant passages separate. It fits many vehicles, among them the 2002-2005 Hyundai Sonata, the 2005-2009 Hyundai Tucson and the 2002-2006 Kia Optima, all with the V6-2.7L engine. It is a direct-fit replacement for the listed applications, and the Buyer's Guide tab has the full list.
APEX describes this part simply as a head gasket. It sits between the cylinder head and the block, where it seals the combustion chambers and the passages that carry oil and coolant between the two. Signs that a head gasket may need replacing include unexplained coolant loss, overheating, white exhaust smoke, milky oil or bubbles in the coolant reservoir. Other faults can cause these symptoms too, so diagnose the engine first. If a failed left-side gasket is the cause, AHG242L replaces it.
Before you install it, check the vehicle service information for the correct fasteners and whether they may be reused. Follow its tightening sequence, and inspect the head and block mating surfaces as the procedure directs.
