Overview – WATER TRANSFER TUBE 3635440 Series
The Cummins WATER TRANSFER TUBE 3635440 fits Cummins cooling positions as the water transfer tube carrying coolant between cores; because multiple part numbers interchange, we list the related series so you can match what is on your machine.
Parts Characteristics
A water transfer tube that carries coolant between the cores and the block, so the heat reaches the cooler and the cabin circuit it was meant for. It carries the line that the cooling loop depends on, so a true, unblocked tube keeps the flow on the right side of the wall.
Applicable Models & Applications
Used at Cummins cooling positions specifying this water transfer tube (series). Match the bore, the bend and the joint against your old tube – water tubes differ in how they route and seal.
Maintenance & Replacement
Inspect for weep at the joint and scale at the bore at every cooling service. A tube that has begun to leak drops the level, and the drop is what overheats the block.
Confirm the tube seats square and the torque holds on fit. A tube canted in its O-ring binds the seal and the joint opens under pressure.
Replace rather than patch a crushed one. A tube dented at the bend restricts flow, and the restriction is what starves the cooler.
Keep the correct water transfer tube for your engine on the bench. It is cheap next to a lost coolant charge, and it is exactly the part missing when a line needs replacing today.
