14.8 Low Coolant Shutdown
Description The low-coolant shutdown system consists of an electronic sensor that monitors
coolant level. The sensor
(a) is mounted to the radiator and wired into the ECM.
The sensor probe (b) is submerged in radiator coolant.
Function If the probe senses no coolant, it sends a signal to the ECM. The ECM program
includes a 10-second timer to protect from nuisance shutdowns. If after the ten
seconds coolant levels are still sensed as being low, the ECM shuts down the
engine. The ECM will then display “LOW COOL LEVEL”. Allow the engine to cool
before adding additional coolant.
If it is necessary to open the radiator, only do so with the engine off, and only when
coolant is cool enough to touch with bare hands. Slowly loosen the radiator cap to
relieve pressure first, before removing it completely.
Note: The sensor may be disabled by unplugging the wire harness. This action will
not shut down the machine.
WARNING
Burn hazard. Pressurized coolant is very hot and can cause serious burns.
►
Do not remove the radiator cap while the engine is hot.
