coolant level indicator on in error

[Melorene]

Cummins just tested the radiator as I am getting an occasional low coolant signal with the check engine lite. It goes out after a few minutes....they said it is a faulty sender in the tank.. where do you get another sender?..they said it is not a Cummins part and to go to Western RV which we know is no longer there..will check with them to see if they updated the computer if there was an update. my rig is a 08. It is not low on coolant and they also pressure tested it. said they had replaced a lot of senders ...I read dshogmans post about the update but is it a Western RV update or a Cummins engine update? Thanks, Mel

you might try removing the sensor and cleaning it
might just be a mineral build up

Mel- when you take the sender out, take it to a NAPA and they should be able to match it (that is if cleaning doesn't do it). Low coolant alarm is a pain as I believe it will put coach in limp mode.

I had the sender changed and now all is fine.. the correct sender is Cummins PN 2872768 and around $135 and takes a few minutes to change..Had it done at cummins rocky Mtn. in Las Vegas.. a great shop and great service..Mel

Mel- where exactly is the sender located?
