Function & Replacement Indicators:

The front crankshaft seal allows the crankshaft to rotate freely while keeping engine oil contained and preventing contaminants from entering the crankcase. Common signs of a failing crankshaft seal include oil leaking from the front crank pulley area, oil pooling beneath the vehicle, or clutch slip caused by oil contamination. Prompt replacement helps prevent costly engine damage from oil loss.

Note: Occasional use of specialized installation tools may be required to seat the seal evenly. Always consult proper repair documentation before installation.
