2007 Volvo Cummins ISX fan turns on with no reason. Can help anyone please.

I would take it right back to the shop that has my 6500.00 and tell them I expect a whole lot better for 6500.00. Its pretty obvious they missed something. Its only been 4 days I'd make them make it right.

 

wait,no worries,same thing happend to me 3months ago,simple,i have ISX,2007,500HP,anyway ,just change the temperature sensor on the top on the INTAKE MANIFOLD(on the driver side).there two sensors temp. and pressure sensor,change the temperature sensor,wich is the smaller one,also there is a sign saying" temp"on the manifold.it is gonna cost you $22.00.cheap .

 

i can't find the serial number,but this sensor is on top of the intake manifold,driver side,there are only two sensors bigger and by him there is a sign press(pressure),and smaller(in diameter)by him sign temp-the signs are stamped on the intake manifold by the sensors,you have to change the smaller one "temp".Open the hood get up on the driver side tire and look a little bit righr it is very clear thay are not hided betwin wires,there is nothing around them,they are only two of them there.

 

good luck,if i find the serial number i'll post it

 

i found the receipt,the part #4088832 M4I
