Overview – HOUSING, HEAT EXCHANGER 3011323
The Cummins HOUSING, HEAT EXCHANGER 3011323 is specified for Cummins engine cooling positions as the heat-exchanger housing and is supplied to the original dimensional and material standard.
Parts Characteristics
A heat-exchanger housing that contains and seals the core, holding the coolant and the medium apart while the heat passes between them. It carries pressure and the seal, so a true, undamaged housing keeps the exchange tight and the fluids from mixing.
Applicable Models & Applications
Used at Cummins heat-exchanger positions specifying this housing. Match the bolt pattern, the port spacing and the core seat against your old housing – exchanger housings differ in how they clamp and seal.
Maintenance & Replacement
Inspect the housing for a cracked flange and a distorted face at every cooling service. A housing that has let the core shift bypasses the exchange, and the bypass is what lets the fluid run hot.
Replace the housing rather than re-torque a warped one. A housing that no longer clamps true lets the core walk and the seal opens.
Re-torque to specification with a fresh gasket. A housing loose in its bolts lets the core weep and the fluid stains the block.
Keep the common heat-exchanger housings for your engine on the shelf. They are cheaper than a cooked core, and they are exactly the part missing when a core needs locating today.
Price Reference (USD)
