Coolant Line/Hose: Testing and Inspection
Cooling System Hose and Clamps
1. CAUTION: Reasonably fresh replacement hoses should be used. Replacement hoses which have been in storage for several years should
be checked for ozone-caused hardening. Hoses which have become hard will be difficult to seal and may break in service.
Inspect the hoses for:
-
Visible signs of deterioration such as cracking or checking. Install new hoses if there is visible deterioration.
-
Swelling near the clamps and at the hose ends. Install new hoses if there is swelling.
-
Oil or oily dirt on the hoses from engine oil leaks or careless filling. Clean off the oil and oily dirt on the hoses. Oil will attack the rubber over
time. If there is weakening or deterioration of a hose, install a new one.
-
Cuts. If a hose is cut other than a very superficial cut, install a new hose.
-
A hose contacting metal parts, especially sharp edges. If a hose is contacting metal parts, loosen the clamps and relocate the hose. In some
cases it may be necessary to put plastic shielding on the hose to protect it. If the hose has already been cut or worn, install a new one.
2. Inspect the clamps.
