Title: M20A-FKS (ENGINE MECHANICAL): ENGINE ASSEMBLY: INSTALLATION; 2020 - 2021 MY Corolla Corolla Hatchback [09/2019 - 06/2021]

INSTALLATION

CAUTION / NOTICE / HINT

CAUTION:

The engine assembly with transaxle is very heavy. Be sure to follow the procedure described in the repair manual, or the engine lifter may suddenly drop.

NOTICE:

When the manual transaxle assembly is removed, be sure to use a new clutch release cylinder with bearing assembly and new installation bolts. Removal of the manual transaxle assembly allows the compressed clutch release cylinder with bearing assembly to return to its original position. Dust from the moving section may damage the seal of the clutch release cylinder with bearing assembly, possibly causing clutch fluid leaks.

HINT:

Perform "Inspection After Repair" after replacing the engine assembly.
