Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Equipment with Perkins 404D engine specifying 422000-34100

- Other 404D installations only when all dimensions, tanks, ports, and mounts match
Product Overview
Coolant stains, bent tubes, recurring pressure loss, or temperature climbing under load can point to a leaking or internally restricted radiator. Replacing it only solves the problem if the fan, belt, shroud, thermostat, pump, hoses, cap, and engine condition are also sound.
Perkins supplies the engine to many equipment manufacturers, so 404D alone is not enough to confirm fit. The core width and height, tank shape, hose necks, cap location, mounting tabs, drain, and cooler provisions must match the removed radiator.

Model, production date, serial number, connector, dimensions, installed options, and previous repairs can affect fitment. Compare the original component and reference information before purchase.
Frequently Asked Questions
Q: Does every Perkins 404D use the same radiator? A: No. The equipment manufacturer designs the cooling module, so dimensions and reference numbers are essential.
Q: Can blocked exterior fins cause overheating? A: Yes. Dust, chaff, and oil can stop airflow even when the radiator does not leak.
Q: How do I confirm this is the correct part? A: Compare both references, core dimensions, overall thickness, hose-neck diameter and position, cap, drain, mounting tabs, fan clearance, and equipment model.
Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket item. Brand, model, and part numbers are used only to identify compatible applications.
