    I have a t600 cat c15 I’m having issue with a red buzzer going off.

    I put the engine fan to auto the water temp reaches 195-200 and the buzzer goes off going uphill. If I leave the fan on Manuel on everything is good but I have to keep my fan running 24/7

    this truck does not have engine temp just water.

    what do you guys think it could it could be my fluids are good. I have to leave the fan on Manuel on in order to prevent the buzzer from going off.

    attached is pic or buzzer. Any help would greatly be appreciated I’ve just fixed a fuel tank issue now this.
