Which engine do you have? My K3 ISX12 has a coolant filter. Itís on the drivers side. Follow the hose from the coolant reservoir under the back of the engine to the divers side. My filter is located where the hose connects to the block.
Recommend you setup a Cummins quickserve account. You can access the maintenance procedures which includes pictures of where the filter is located. You will need your engine serial number to setup the account.
