scale forms in the hose, clean with the scale inhibitor
or its equivalent.
B
Checking radiator hoses and clamp

A
Be sure to check radiator hoses and hose
clamps periodically. If radiator hose is
damaged or coolant leaks, overheats or severe
burns could occur.
Check to see if radiator hoses are properly fixed every 200
hours of operation or 6 months, whichever comes first.

clamp securely.
