The one-piece rear Crankshaft Seal is pressed into the engine block and the crankcase reinforcement section. Begin by removing the transaxle, the clutch components if equipped, and the
Flywheel/driveplate. For 2016 and later 1.4L and all 1.8L engines, the crankshaft position sensor should be removed. After the flywheel is taken off, detach the crankshaft position sensor encoder wheel and reluctor ring from the end of the crankshaft. Caution is advised to avoid placing the crankshaft encoder wheel near magnets or magnetic fields, as it is easily damaged; if it is cut or exposed to a magnetic field, it must be replaced. Pry out the old seal using a special seal removal tool or a flat-blade screwdriver, taking care not to scratch or damage the crankshaft sealing surface or the bore in the engine block to prevent oil leaks after the new seal is installed. Clean the crankshaft and seal bore thoroughly, de-greasing these areas with a rag soaked in brake system cleaner, and lubricate the lip of the new seal and the outer diameter of the crankshaft with clean engine oil. Position the new seal onto the crankshaft, ensuring the edges are not rolled over, and use a special rear Crankshaft Seal installation tool or a socket of the exact diameter to drive the seal in place, ensuring it is flush along the entire circumference of the engine block and the crankcase reinforcement section. If marked, the words THIS SIDE OUT on the seal must face out, toward the rear of the engine. The remainder of the installation follows the reverse order of removal.
