Daily before starting the engine, check the coolant level of the coolant
reserve bottle. The coolant level should be between the “FULL” and
“LOW” lines when the engine is cool.
1. The pressure cap on a pres-
sure cooling system has a
control valve that operates as a
SAFETY RELIEF VALVE to
keep the pressure within the
system operating range. Oper-
ating the engine without a
pressure cap or with a pressure
cap that has a control valve
that is not set to operate at the
correct pressure, can cause
damage.
2. A pressure cooling system de-
creases the loss of coolant
caused by evaporation or boiling. The system must have good seals
at the radiator cap, hoses and hose connections. It is important that
you stop ALL LEAKS OF ANY SIZE as soon as the leaks are found.
A small leak can become a large flow when pressure is increased in
the cooling system. While the tractor is in operation, a weak hose can
break and cause injury or damage. Check all hoses and hose
connections with frequency. KEEP HOSES, HOSE CONNECTIONS
AND PRESSURE CAP IN GOOD CONDITION.
PRESSURE CAP
Check and service cooling system according to maintenance in-
structions. Hot coolant can spray out if radiator cap is removed while
system is hot. To remove radiator cap, let system cool, turn to first
notch, then wait until all pressure is released. Scalding can result
from fast removal of radiator cap.
