Hi,my 2001 LB7 low coolant light comes on when its full of coolant and I just replaced the reservoir which comes with a built-in sensor and the light still comes on,does any have some advice on fixing this problem without taking it to the shop?Please help me.............

 

welcome to diesel bombers and if i was you double check your wiring and your plug where its plugged in keep us informed i am sure that some answers will come along that will help if this doesnt

 

Is there anything else in your coolant besides coolant, like any oil?

does it smoke at start up at all, and does the radiator hose get hard and stays hard over night?

when was the last time the injectors were replaced, if they were replaced.

 

same thing happened to one of our LB7's. started replacing sensors. no help. then took off the radiator completly only to find one of the seals was bad.
