HOSE LEAKAGE
General Information:
A leaking hose can be detected by obvious wet areas or engine overheating.
Weak hoses feeling soft and spongy should
be reinforced with metal if repaired.
The soft spongy feeling indicates the rubber is deteriorated and will not withstand
normal cooling system pressures.
Option 1, below, provides two procedures for repairing a small leak in a hose.
Option 2
shows how to correct a larger split in a hose.
