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 programincludes a 10-second timer to protect from nuisance shutdowns. If after the tenseconds coolant levels are still sensed as being low, the ECM shuts down theengine. The ECM will then display “LOW COOL LEVEL”. Allow the engine to coolbefore adding additional coolant.If it is necessary to open the radiator, only do so with the engine off, and only whencoolant is cool enough to touch with bare hands. Slowly loosen the radiator cap torelieve pressure first, before removing it completely.Note: The sensor may be disabled by unplugging the wire harness. This action willnot shut down the machine.WARNINGBurn hazard. Pressurized coolant is very hot and can cause serious burns.► Do not remove the radiator cap while the engine is hot.
